SignedXML.CheckSignature Always Fails

April 3, 2009, 7:06 am
$

I don't think I posted my original question in the correct forum, so I'm going to close that one and post here.

I'm currently working on a project which requires the XML posts to be digitally signed. I do not seem to have any luck with getting any test posts from our client to validate with the below code:

publicstaticbool verifySignature(string xmlData)

{



    XmlDocument theDocument = new XmlDocument();

    XmlNodeList nodeList;

    SignedXml signedDocument;



    theDocument.PreserveWhitespace = true;

    theDocument.LoadXml(xmlData);

    signedDocument = new SignedXml(theDocument);



    nodeList = theDocument.GetElementsByTagName(

        "ds:Signature");



    signedDocument.LoadXml((XmlElement)nodeList[0]);



     return signedDocument.CheckSignature();



}

The posts are signed using the XML Signature tag with a namespace of "ds". I am simply base64 decoding the post and sending it straight to here without any modifications of whitespace or casing.

Any help would be greatly appreciated!

Needing to query each repeated node for a specific child node, always getting the first node value

June 12, 2019, 11:34 am

Take for example the following prototype XML layout

<records><record><valuea>foo1</valuea><valueb>bar1</valueb><valuec>bob1</valuec></record><record><valuea>foo2</valuea><valueb>bar2</valueb><valuec>bob2</valuec></record><record><valuea>foo3</valuea><valueb>bar3</valueb><valuec>bob3</valuec></record></records>

So I am using a call to .SelectNodes("//records/record") and iterating through within a For Each within the returned list.

The iteration loop count is correct.

Then I make a call to .SelectSingleNode("//records/record/valueb")

For some reason I always get the first record instance. The object the For Each has received as the iteration valuable contains the correct values, but somehow making the call .SelectSingleNode against it to obtain the specific value the program needs retrieves the always the first record's valueb. The new object the For Each returns seems to have knowledge it is actually part of a larger set of data... not the individual record from the record set.

How can I correctly iterate through the record list and obtain each distinct record's valueb?

I am coding in Access / VBA.

TIA!

Hi,
We are using VS2013 and using XSLT1.0. With XSLT1.0 we are able to get the result from <g class="gr_ gr_13 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="13" id="13">XML</g> file. Now we have a requirement to use XSLT2.0.
Is VS2013 or later versions have support to use XSLT2.0?
If not, Is there any alternate ways to use XSLT2.0?

Thanks,

How to Parse XML into a C# object?

<Event Id="102" />

What would be the simplest way to read and parse this XML string into a C# object (I'm not showing the private members and properties for simplicity)

class EventInput
{
public int group;
        public List<int> EventIds = new List<int>();

Coding problem writing XML-Word text in Windows 10

Hi All,

I have distributed a C++ application that writes XML files for Word. It works fine for most of my users but for some of them the text is written as coded. For example, normally my application writes:

<w:t>1. Dati generali</w:t>

whereas for these users it writes:

<w:t>葬&#x02;$h&#x0A;&#x01;</w:t>

Since all these users run the application in Windows 10, I thought that the problem could be some settings in Windows 10 itself, so I deeply investigated in Windows Control Panel what settings could be (local language, region, etc.), but with no luck.

Any help would be greatly appreciated.

Thanks,

Gianni

HELP! Using Dynamic LINQ with XML...

i am trying to use dynamic LINQ to query an XML document, as indicated is possible on Scott Guthrie's blog post here:

http://weblogs.asp.net/scottgu/archive/2008/01/07/dynamic-linq-part-1-using-the-linq-dynamic-query-library.aspx

below is my code sample:

-----------

XElement pViewElement = XElement.Load(...);

string sFilter = @"Convert.ToInt32(Attribute("Age").Value) >= 60)";
List<XElement> pViewResults = pViewElement.Elements().AsQueryable().Where(sFilter).ToList();

-----------

however, when this code executes, i receive the following error:

"No applicable method 'Attribute' exists in type 'XElement'"

does anyone know why this is? obviously, that method DOES exist when i write the code normally. i cannot find an XML example with dynamic LINQ anywhere. rather, the only good examples are against a SQL backend.

your help is greatly appreciated in advance.

Hello,

i have an .XML file that i update daily and would like to figure out a way to display certain information in that file on my lock screen. 

More specifically, i work for a large company and we have 350+ computers that syncronize to my computer. There is an app that must be up to date and right now the managers have to log in to each computer  to make sure the app us up to date. if i could pull the date from this XML file and display it on the lock screen it would save SO much tome for my managers. 

I also have an .exe file that also shows the date. Could I use that? Or is it possible to create an app that displays the update date on the lock screen? Kind of like the Weather app that displays the weather under the date and time.
