Large XML file break up

Hi,

I want to write data to a xml file by breaking it into two sections. One section will be xml data and other section will be in the form of binary data so as to minimize file size. What could be the best approach for this. Still I should get xml file validated against my xsd file.

Thanks

Exception during msxml6 FreeObjects

Hi,

I have a relatively complicated test written in VB.NET. This test invokes COM objects through interops. Those COM objects intern invoke functionality in the MSXML6.dll. My test finishes successfully and I see the last print statements I've made in the test. After the test has finished it appears kernel32 is invoking ExitProcess. At that time i get a pop up window that states

"The

instruction at "0x58830fa1" referenced memory at "0x00000038". The memory could not be

"read""

I was able to get a dump file using windbg. The stack looks like this:

Has anyone seen a similar issue? Of course I googled (oops i mean binged :) ) and couldn't seem to ask the correct question, or no one has experienced what I am.

I am running my test on a 2003 SP2 VM.

Smart pointers are being used and the create call that is being may is:

#import "msxml6.dll" rename_namespace("ExMSXML")

ExMSXML::IXMLDOMDocument2Ptrm_XMLDocument;

m_XMLDocument.CreateInstance(_T("Msxml2.FreeThreadedDOMDocument.6.0"));

Thanks in advance for any help you all can provide.

XSD generated code with string restrictions

≫ Next: how to deserialize xml with structure of abitrary nested layers of base class?

≪ Previous: Exception during msxml6 FreeObjects

Hello all,

In my application, i am generating .cs code file using XSD.exe tool. I have added few restrictions in my XSD for string data types. These restrictions are nothing but the length of the string element present in the XML file.

How i can get these restrictions in my XSD generated classes as an attribute or any other way? Here is the XSD restriction for which i want some information in the XSD tool generated classes.

<xs:simpleType name="AsciiText_20_FixedLength_Type"><xs:restriction base="xs:string"><xs:maxLength value="20" /></xs:restriction></xs:simpleType>

Thanks in advance,

how to deserialize xml with structure of abitrary nested layers of base class?

≪ Previous: XSD generated code with string restrictions

let say i want to represent arithmetic expression using xml:

<?xml version="1.0" encoding="utf-8" ?><expr><add><num>10</num><num>20</num></add></expr>

and here is my classes to represent this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Test
{
    public abstract class Evaluable
    {
        public abstract int Eval();
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Serialization;

namespace Test
{
    [Serializable]
    [XmlRoot("expr")]
    public class Expr
    {
        [XmlElement]
        public Evaluable Evaluable { get; set; }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Serialization;

namespace Test
{
    [Serializable]
    [XmlRoot("add")]
    [XmlType("add")]
    public class Add : Evaluable
    {
        [XmlElement]
        public List<Evaluable> Elems { get; set; }

        public override int Eval()
        {
            return Elems.Select(e => e.Eval()).Sum();
        }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Serialization;

namespace Test
{
    [Serializable]
    [XmlRoot("num")]
    [XmlType("num")]
    public class Num : Evaluable
    {
        [XmlText]
        public int Val { get; set; }

        public override int Eval()
        {
            return Val;
        }
    }
}

but it doesn't work, and it's reasonable, since Serializer doesn't know any thing about the subclass. but how to make it work?

here is my deserialization code:

var serializer = new XmlSerializer(typeof(Expr), new[] { typeof(Add), typeof(Num) });
            Expr expr = null;
            using (var file = new StreamReader("expr.xml"))
            {
                expr = serializer.Deserialize(file) as Expr;
            }

From what I understand, the first quoted bit refers to a SignedPropertiesElem_0 element in the same file. I am trying to determine exactly what it refers to - what piece of code exactly should be selected and used later on for canonicalization and then calculating a digest value. Is it this:

<SignedProperties Id="SignedPropertiesElem_0"><SignedSignatureProperties><SigningTime>2014-08-21T06:09:55Z</SigningTime><SigningCertificate><Cert><CertDigest><DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256" xmlns="http://www.w3.org/2000/09/xmldsig#"/><DigestValue xmlns="http://www.w3.org/2000/09/xmldsig#">JQ0kZvd0mtXQPA/RTuYV9iuc346tznvN9MoAd/0jNyM=</DigestValue></CertDigest><IssuerSerial><X509IssuerName xmlns="http://www.w3.org/2000/09/xmldsig#">CN=Nacionalinis sertifikavimo centras (IssuingCA-B),OU=Nacionalinis sertifikavimo centras (NSC),O=Gyventoju registro tarnyba prie LR VRM - i.k. 188756767,C=LT</X509IssuerName><X509SerialNumber xmlns="http://www.w3.org/2000/09/xmldsig#">1315010063538360283821765366094690</X509SerialNumber></IssuerSerial></Cert></SigningCertificate><SignaturePolicyIdentifier><SignaturePolicyImplied/></SignaturePolicyIdentifier></SignedSignatureProperties></SignedProperties>

Or this:

<SignedSignatureProperties><SigningTime>2014-08-21T06:09:55Z</SigningTime><SigningCertificate><Cert><CertDigest><DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256" xmlns="http://www.w3.org/2000/09/xmldsig#"/><DigestValue xmlns="http://www.w3.org/2000/09/xmldsig#">JQ0kZvd0mtXQPA/RTuYV9iuc346tznvN9MoAd/0jNyM=</DigestValue></CertDigest><IssuerSerial><X509IssuerName xmlns="http://www.w3.org/2000/09/xmldsig#">CN=Nacionalinis sertifikavimo centras (IssuingCA-B),OU=Nacionalinis sertifikavimo centras (NSC),O=Gyventoju registro tarnyba prie LR VRM - i.k. 188756767,C=LT</X509IssuerName><X509SerialNumber xmlns="http://www.w3.org/2000/09/xmldsig#">1315010063538360283821765366094690</X509SerialNumber></IssuerSerial></Cert></SigningCertificate><SignaturePolicyIdentifier><SignaturePolicyImplied/></SignaturePolicyIdentifier></SignedSignatureProperties>

Or some other part of it?

I tried the first one, then letting it through a StylusStudio canonicalization OR soapclient.com canonicalizer (both seem to return identical results), which results in this:

<SignedProperties Id="SignedPropertiesElem_0"><SignedSignatureProperties><SigningTime>2014-08-21T06:09:55Z</SigningTime><SigningCertificate><Cert><CertDigest><DigestMethod xmlns="http://www.w3.org/2000/09/xmldsig#" Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"></DigestMethod><DigestValue xmlns="http://www.w3.org/2000/09/xmldsig#">JQ0kZvd0mtXQPA/RTuYV9iuc346tznvN9MoAd/0jNyM=</DigestValue></CertDigest><IssuerSerial><X509IssuerName xmlns="http://www.w3.org/2000/09/xmldsig#">CN=Nacionalinis sertifikavimo centras (IssuingCA-B),OU=Nacionalinis sertifikavimo centras (NSC),O=Gyventoju registro tarnyba prie LR VRM - i.k. 188756767,C=LT</X509IssuerName><X509SerialNumber xmlns="http://www.w3.org/2000/09/xmldsig#">1315010063538360283821765366094690</X509SerialNumber></IssuerSerial></Cert></SigningCertificate><SignaturePolicyIdentifier><SignaturePolicyImplied></SignaturePolicyImplied></SignaturePolicyIdentifier></SignedSignatureProperties></SignedProperties>

and then calculating the digest value using online hash calculation tools. They all returned the same result, but that result is different from the one in the xml file:kOlNXyBs6oSP9hbh+4niZMNQ9OsOCzYhkSYYG4YdHQU=

What am I doing wrong? What part of the xml document should I copy and paste into the canonicalizer and then into digest calculator?

Private Property Let IXMLDOMNode_dataType(ByVal RHS As String)

End Property

Private Property Get IXMLDOMNode_dataType() As Variant

End Property

As shown, the type is not the same for both: "variant" respectively "string". At the end "variant" is correct, I've checked in objectcatalog. This code cannot be compiled of course and changing "string" to "variant" leads to another error: "The type is not the same as in a function with the same Name".

I currently don't see a solution, any suggestions?

Hi,

I have an issue; I know that we cannot traverse back in xslt. The problem is.

I have the sample xml like this.

<SalesInvoices>
<Invoice>
  <NumberOfEntries>1367</NumberOfEntries>
  <InvoiceNo>232</InvoiceNo>

I need to convert the above XML to the format that I had mentioned in the sample; where within each Invoice the Line set of elements repeats. I am not able to arrive at a logic in the xslt; could you please let me know if this is possible.

I tried the following in the XSLT; but I am not able to create 2 sub child set of Line elements for each Invoice; this creates one set of Invoice for each record; I am not sure if I can arrive at the expected logic as per the sample xml in the xslt. This a very critical situation for me, any advice on this will be of much help. Thanks.

Removing node from xml file?

January 19, 2015, 6:50 am

≫ Next: MSXML2.ServerXMLHTTP problem, moved from server 2003/IIS6 to 2008/IIS7, simple xml between ASP pages broken

≪ Previous: Unable to traverse back in xslt

When a user clicks a "Check Out" button, their name is supposed to be removed from an xml file, and subsequently removed from a list box, indicating they left a meeting. However,I have encountered Null Reference Exceptions during debugging because _xmlNode is null. From my research on this issue, it seems the problem lies in the declaration of XmlDocument and the passing of its instance _xmlDocument to deleteAttendee(). However, I believe that I declared _xmlDocument correctly, and am having difficulty finding where my strategy went off track. I would appreciate any pointers that could help steer me back in the right direction. Thanks!

protected void checkOutButton_Click(object sender, EventArgs e)
        {
            string fileName = Server.MapPath("~/App_Data/attendees.xml");
            XmlTextReader _xmlTextReader = new XmlTextReader(fileName);
            XmlDocument _xmlDocument = new XmlDocument();
            _xmlDocument.Load(_xmlTextReader);
            _xmlTextReader.Close();

            deleteAttendee(inMeetingListBox.SelectedItem.Text, fileName, _xmlDocument);
            inMeetingListBox.Items.Remove(inMeetingListBox.SelectedItem);


        }
static void deleteAttendee(string attendeeName, string fileName, XmlDocument xmlDoc)
        {
            string test = xmlDoc.DocumentElement.ToString();
            XmlElement _xmlElement = xmlDoc.DocumentElement;
            XmlNode _xmlNode = _xmlElement.SelectSingleNode("attendee[@name='asp']");
            _xmlElement.RemoveChild(_xmlNode);

MSXML2.ServerXMLHTTP problem, moved from server 2003/IIS6 to 2008/IIS7, simple xml between ASP pages broken

≫ Next: Get the output in List from the XML

≪ Previous: Removing node from xml file?

Final update>>>

Update: I moved the target to the production server/URL and it works fine(calling from new server, target on production). So I reversed(calling from production server and target on new server) and it works too. So it would appear that there is an issue with an ASP script using MSXML2.ServerXMLHTTP to comm with another ASP script on the same server, atleast in server 2008/IIS7. Works fine with Server 2003/IIS6. Strange step backwards it would seem to me, oh well. Perhaps this post here will help someone else.

First update>>>

Well, done some more and just read this:

...calls to ServerXMLHTTP must not send requests



to the same virtual server on which the calling script is executing,



correct? IOW, the script http://www.myserver.com/xmlhttpcaller.asp must not



reference any other ASP script on www.myserver.com when calling XMLHTTP.



Doing so can deadlock the script engine.






Even calling an XML source on a different virtual but same physical server



can cause issues, depending on app pools, isolation settings, threading



models of COM objects being used, etc. ...

If this is accurate it would seem that this may be the underlying issue with the problem I am having. If so, I find it curious it has never been a problem on the current production server but if so I will make appropriate changes. Anyone comment specifically on this info above?

original post>>>

I've read hours online about this but have very little to show for it. Basic gist of what's happening: ASP page trying to XML to another ASP page in the same dir. Following code sits for 30 seconds and times out. It actually gets to the target page at the *end* of the 30 seconds(test email with time-stamp being sent from there) but no response returned. Get method does resolve the querystring but switch to using post and no data at the target page. No response from the target page gets back to initiating page. As stated, this works fine on the current server running Server 2003. I've gone through roles, proxycfg(direct access as with the current server), it's a page calling a page in the same directory. In the IIS manager I have set the ISAPI restrictions to allowed for c:\windows\system32\msxml3.dll. I have started WinHttpAutoProxySvc. Perhaps a specific feature I need to install or a service to run or...?

error:

msxml3.dll error '80072ee2'

The operation timed out

/testXML_2.asp , line 26

line 26 is the xml.send line

Simple code being tested to get the xml working on the new server(testXML_2.asp):

IF UCASE(Request.ServerVariables("HTTPS")) = "ON" THEN
    vWork2 = cfgURLBaseSecure & cfgURLDir
ELSE
    vWork2 = cfgURLBase & cfgURLDir
END IF

vXMLAdr = vWork2 & "/testXML.asp"
vXMLStr = "?EC=E1234567890"

SET xml = Server.CreateObject("MSXML2.ServerXMLHTTP")

vWork = vXMLAdr & vXMLStr
xml.open "GET", vWork, FALSE
xml.send

'xml.open "POST", vXMLAdr, FALSE
'xml.send vXMLStr

IF xml.status = 200 THEN
    vReturn = xml.responseText
ELSE
    vReturn = "FAIL"
END IF

Target page code(testXML.asp):

vWork2 = Request.QueryString("EC")
'vWork3 = Request.form("EC")

vWork = "testXML - Time: " & now() & " querystring: " & vWork2 & " form: " & vWork3
CALL SendErrorEmail("testXML - new",vWork,"")

Response.Write "Got There and Back"
Response.end

The reason the one ASP page is using the XML object to contact another is the main use of the target is AJAX with other pages but sometimes the system needs to perform the same function thus this method of interacting with the AJAX page via the system vs a user via a browser and I would prefer to keep the code in one place. Perhaps there is an alternate I should be considering but the above scenario has been in production just fine for years now.

Any help?

Thanks in advance,

Ken

XSLT producing different results via debugger and xslt.Transform()

January 26, 2015, 12:44 pm

≫ Next: Importing complex xml into a DataSet

≪ Previous: IXMLDOMDocumentPtr save method is saving the tags in single row.

I'm producing the body of an email via an xsl. I've been having a problem with the html nested inside a <table> tag not displaying correctly. With a bit of help from the good folks over at the asp.net forums, I've tracked the problem down to getting different results if I run the xsl via the debugger or via a compiled transform.

When I debug the xsl it produces

      <table border="1" cellpadding="4" cellspacing="0" style="..." id="tmsEmailTable">
        <tr>
          <th width="50%" align="center"><b>Issue</b></th>
          <th width="50%" align="center"><b>Resolution</b></th>
        </tr>
        <tr>
          <td>Missing Acknowledgement date</td>
          <td><p> Test test</p></td>
        </tr>
        <tr>
          <td>Missing Agent and/or Seller signature</td>
        ....
    </table>

And that's absolutely correct and displays perfectly if I save the result as an html file. But when I use xslt.Transform(..), where xslt is a compiled transform, it produces

<table border="1" cellpadding="4" cellspacing="0" style="..." id="tmsEmailTable">
            <tr><th width="50%" align="center"><b>Issue</b></th><th width="50%" align="center"><b>Resolution</b></th></tr>
            <tr>
                <td>
                    Missing Acknowledgement date
                </td>
                <td></td>
            </tr>
        </table>
    </p><p> Test test</p></td></tr><tr>
        <td>Missing Agent and/or Seller signature</td>
        <td>
     .....
    </table>

And to make it even more interesting, that extra </table> tag and the misplaced table data only occur on the first table row, but the table rows are generated by an xsl:for-each.

The relevant bit of the xsl is:

          <table border="1" cellpadding="4" cellspacing="0" style="..." id="tmsEmailTable">
            <tr>
              <th width="50%" align="center">
                <b>Issue</b>
              </th>
              <th width="50%" align="center">
                <b>Resolution</b>
              </th>
            </tr>

            <xsl:for-each select="emailbody/checklist/item">
              <xsl:if test="string-length(select='issue')>0">
                <tr>
                  <td>
                    <xsl:value-of select="issue" disable-output-escaping="yes" />
                  </td>
                  <td>
                    <xsl:value-of select="resolution" disable-output-escaping="yes" />
                  </td>
                </tr>
              </xsl:if>
             </xsl:for-each>

          </table>

The code that generates the compiled transform and the (incorrect) output is:

Dim xslt As XslCompiledTransform = New XslCompiledTransform(True)
'Dim xslt As XslTransform = New XslTransform

xslt.Load(templatePath)

            Dim objStream As Stream = New MemoryStream(UTF8Encoding.UTF8.GetBytes(xmlData))
            Dim strbldrXML As StringBuilder = New StringBuilder()
            Dim objXmlReader As XmlReader = XmlReader.Create(objStream)
            Dim objXmlWriter As XmlWriter = XmlWriter.Create(strbldrXML)

xslt.Transform(objXmlReader, objXmlWriter)

I've checked that templatePath is pointing to the right file, and the source file I'm debugging the xsl against was copied from the xmlData parameter, so I know the same stuff is getting fed into it.

I've been chasing this for days, and I'm about ready to quit and go get a job at a fast food joint. I'm not wonderful with xsl in general, or xsl in .NET in particular. Somebody PLEASE tell me I'm doing something stupid....

(A prolific PowerShell poster suggested I come over here....)

I have a schema but it doesn't import correctly into a DataSet with the expected table names.

There is more but I think if this gets solved the rest will, what am I doing wrong with the table names?

My PowerShell code (actually, the same thing happens with c#):

clear-host

$dsXml = new-object "System.Data.DataSet"
$dsXml.ReadXmlSchema("C:\temp\xml\mySchemaTest.xsd")
$dsXml.ReadXml("c:\temp\xml\myXmlTest.xml", 'ReadSchema')


Write-Host "Table names in dataset"
Write-Host "======================"
foreach ($table in $dsXml.Tables)
{
	Write-Host $table.TableName
}

The schema (tested as valid)

<?xml version="1.0" encoding="utf-8"?><xs:schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I have the below XML, from which I need to generate multiple groups within groups.

</Table>
</NewDataSet>
</SalesInvoices2>
</XmlContent>

Expected Output:

I had tried the below XSLT - which is not working as expected, however with slight changes to the approach, I am able to get the one outer loop , i.e., Journal would get repeated twice, but not other elements within that.

<xsl:template match="/">
    <xsl:apply-templates select="XmlContent/SalesInvoices2"/>
</xsl:template>
<xsl:key name="EntryId" match="Table" use="F3" />
<xsl:template match="NewDataSet">
    <NewDataSet>
      <xsl:apply-templates select="//Table[position()>1 and generate-id(.) = generate-id(key('EntryId', F3)[1])]" />
    </NewDataSet>
</xsl:template>

<xsl:template name="Table" match="Table">
    <NumberOfEntries>
        <xsl:value-of select="F2"/>
      </NumberOfEntries>
    
    <Journal>
      <JournalId>
        <xsl:value-of select="F3"/>
      </JournalId>
      <Description>
        <xsl:value-of select="F4"/>
      </Description>

<xsl:for-each select="key('EntryId', concat(F3,'|',F5[1]))">
        <Transaction>
          <TransactionId>
            <xsl:value-of select="F5"/>
          </TransactionId>
          <SourceID>
            <xsl:value-of select="F6"/>
          </SourceID>
          
          <xsl:for-each select="key('EntryId', F3)">
            <Line>
              <LineNumber>
                <xsl:value-of select="F6"/>
              </LineNumber>
              <OrderDate>
                <xsl:value-of select="F7"/>
              </OrderDate>
              <ProductCode>
                <xsl:value-of select="F8"/>
              </ProductCode>
              <ProductDescription>
                <xsl:value-of select="F9"/>
              </ProductDescription>
            </Line>
       </xsl:for-each>
        </Transaction>
        </xsl:for-each>
    </Journal>
   </xsl:template>
</xsl:stylesheet>

In the given sample - Journal should get repeated twice and within first Journal set of elements - I should get two transaction set of elements within the first set of transaction there should be 3 Line set of elements and in the second transaction set there should be 2 Line set of elements.

Could you please help me on the solution, how I can have multiple groups and loop though the group and create another group within already constructed groups.

XMLDocument.Validate works on some machines but not on others

≪ Previous: Grouping within a group in XSLT 1.0

Hi All

I have a problem which I cannot Solve , I have a routine that Validates a node in a document against a XSD file using the XmlDocument.Validate method. This works fine on several machines but on a different network using the Same Document and schema files validate fails with a validation exception element not found . I cannot figure out why the exact same files and application should be successful on one machine and unsuccessfull on another. I have used Filemon to see if their are ACCESS DENIED problems but there are none.

I have reinstalled the framework 2.0, to no avail

≪ Previous: XMLDocument.Validate works on some machines but not on others

Hello all. I am studying XSLT in school and need some help.

Display the following: Software titles for each operating system sorted by category. Sorting is not the problem. I am having an issue with displaying software titles for each operating system. Here is the XML and the XSLT.

<?xml version="1.0"?><!-- Note: For many of the wonders, the experts do not agree on precise dates or construction dimensions.  In these cases, I chose a year or dimension in the middle of the range so all attributes could be numeric. --><software_inventory><software xmlns:xsi="Software.xsd"><title>Adobe Photoshop</title><vendor>Adobe</vendor><category>Graphics</category><support_platforms><Platform>Windows 7</Platform><Platform>Windows 8</Platform><Platform>Windows 8.1</Platform></support_platforms><Approved_Versions><Version Hardware_Requirements="4GB Ram 2GB Hard Drive" Software_Requiremnts="32/64 bit" Price="399">CS 5.5</Version></Approved_Versions></software><software><title>Winzip</title><vendor>Winzip International</vendor><category>Utility</category><support_platforms><platform>Windows Vista</platform><platform>Windows 7</platform><platform>Windows 8</platform><platform>Windows 8.1</platform></support_platforms><Approved_Versions><Version Hardware_Requirements="2GB Ram 250MB Hard Drive" Software_Requiremnts="32/64 bit" Price="29.99">19</Version></Approved_Versions></software>

There are more titles in the XML, but I didn't include them.

Here is the XSLT

<h1>Software Titles for each operating system, sorted by category</h1><table border="1"><tr><th>Software Title</th><th>Operating System</th><th>Category</th></tr><xsl:for-each select="software_inventory/software"><xsl:sort select="support_platforms/platform"/><xsl:sort select="category"/><tr><td><xsl:value-of select="title"/></td><td><xsl:for-each select="support_platforms/platform"><xsl:value-of select="platform"/><xsl:text>&#13;</xsl:text></xsl:for-each></td><td><xsl:value-of select="category"/></td></tr></xsl:for-each></table>

Here is a screen shot of the output. What I would like is for each Platform / operating system to show in the same cell, so the adjacent cells will grow taller to accommodate.

What am I doing wrong?

Locating data in my XML file using C#

February 2, 2015, 7:47 am

≫ Next: Finding an entry where I have two values each in different nodes

≪ Previous: nested for-each not working

Hi !

I have a XML file. Here is a snippet:

<Layers Count="9"><Layer Name="layer0" Type="Polygon"><OverlapNames Count="2"><OverlapName Name="layer1"/><OverlapName Name="layer2"/></OverlapNames><CommonNames Count="0"></CommonNames><SnapNames Count="1"><SnapName Name="layer3"/></SnapNames></Layer>

Now, if I have a "layer" is there a quick way to find the node "Layer" that name a name "layer0".

Secondly, is there a way to not only locate the node but return true if the "type" is a certain value? In the above example layer0 is a polygon. So if I encounter a point entity on layer0 and I try to find a layer where name="layer0" and type="point" it should return empty.

Thanks for clarification on right way to parse the XML data file to locate the information I need.

Finding an entry where I have two values each in different nodes

February 3, 2015, 8:03 am

≫ Next: XSLT - Selecting Min, Max, and Avg Attribute Values - Need Data from different Levels

≪ Previous: Locating data in my XML file using C#

Can I do this with one XPath? If I have "layer1" and "layer2" ....

Layers/Layer[@Name=\"layer1\"] <---- This has to be true. But also ....

Layers/Layer/SnapNames/SnapName[@Name=\"layer2\"] <---- This has to be true

I did it like this:

                                    // Find main node
                                    XmlNode nodeLayer = xmlOrbis.SelectSingleNode(String.Format("Layers/Layer[@Name=\"{0}\"]", strLayer));
                                    if(nodeLayer != null)
                                    {
                                        String strLayer2 = m_dictLayers[pSegment2.layerID];
                                        XmlNode nodeLayer2 = xmlOrbis.SelectSingleNode(String.Format("SnapsNames/SnapName[@Name=\"{0}\"]", strLayer2));
                                        if(nodeLayer2 == null)
                                        {
                                        }
                                    }

Can I simplify it into one call? Something like:

XmlNode nodeLayer = xmlOrbis.SelectSingleNode(String.Format("Layers/Layer[@Name=\"{0}\"]/SnapNames/SnapName[@Name=\"{1}\"]", strLayer, strLayer2));

I don't know if that is viable ...

Hello all. I thing my problem is that the attribute is on a couple of nodes down from the node that I need to select. Also, I need to pull values from different levels. Not sure how to construct the XPath.

I need to select all graphics software (category) that runs on linux (platform) and I need the minimum, maximum, and average price (version/@price). This seems very complex to me, and I really need some help.

Thanks,

David
