I have already downsized my XML fragment to the Node I want. The code works below ( there are 2 workable approached ) - but I thought I could use LINQ and lamda expression to query from the start - rather than load the dictionary and then clear
it if the conditions are not met ( = an attributeName has a specific value ) - ideas ???
public Dictionary<string, string> GetElementAttributesWithKeyByValueCondition(string XMLFragSource, string attribValue, string attribName)
{ // get all the attributes from the element if attributeValue & attributeName match....
var myKeyValReturn = new Dictionary<string, string>();
bool found= false;
try
{
XElement allData = XElement.Parse(XMLFragSource);
if (allData != null)
{
IEnumerable<XAttribute> telementAttrib = allData.Attributes();
foreach (XAttribute xattr in telementAttrib)
{
myKeyValReturn.Add(xattr.Name.ToString(), xattr.Value); //&& xattr.Name=attribName) what's this ? cannot use && ?
if (xattr.Name == attribName)
{
if (xattr.Value == attribValue)
{ found = true;}
}
}
if (!found)
{
myKeyValReturn.Clear();
}
// alternate to bool flag
IEnumerable<KeyValuePair<string,string>> kvp= myKeyValReturn.Where(a=>(a.Value==attribValue && a.Key==attribName));
if (kvp.Count()<1)
{
myKeyValReturn.Clear(); // did not find it.
}
// how does this work ??
IEnumerable<XAttribute> tAttrib =
from a in allData.Attributes()
where a.Value==attribValue
select a ;
}
}
catch (Exception e)
{
string errorMessage = string.Format("Fn GetElementAttributesWithKeyByValueCondition failed {0},{1}", e.Message, XMLFragSource);
}
return myKeyValReturn;
}Thanks
