Question

I have a xml structure:

 <pit>
  <ROW TestID="47855" ExecutionID="1510034507" TestName="USHP" AssertionName="Check News" Status="1" TestLatencyMs="5448" Date="2011-11-29 01:43:45.117" HttpCode="" Error="" TestOwner="mdk" AssertionID="119117" /> 
  <ROW TestID="47855" ExecutionID="1510028579" TestName="USHP" AssertionName="Check News" Status="0" TestLatencyMs="7312" Date="2011-11-29 01:41:46.273" HttpCode="" Error="" TestOwner="fdxk" AssertionID="119117" /> 
  <ROW TestID="47855" ExecutionID="1510022153" TestName="USHP" AssertionName="Check News" Status="0" TestLatencyMs="5860" Date="2011-11-29 01:39:44.153" HttpCode="" Error="" TestOwner="klo" AssertionID="119117" /> 
  </pit>

and I am trying to use this query to fetch my ExecutionIDs but to no avail 🙁 I don’t know what is wrong.

    List<int> executionIdList = new List<int>();
    try
    {
        executionIdList = (from result in xDoc.Root.Descendants("ROW")
                            where result != null &&
                            result.Attribute("Status").Value.Equals("0", StringComparison.CurrentCultureIgnoreCase)

                           select result.Attributes("ExecutionID")).FirstOrDefault().Select(x => int.Parse( x.Value)).ToList();
    }

I get only the first value with the above query.

You can fetch yout ExecutionIds from the XDocument as shown below:

XDocument doc = XDocument.Load(@"C:\Sample1.xml");
List<string> ids = doc.Descendants("pit").Elements().Select(i => i.Attribute("ExecutionID").Value).ToList();

The above code loads the xml from the file Sample1.xml and then fetches all the executionIDs into a list object. You can add more conditions to the query if needed like you are checking if the status value is “0”. Below is the code with the condition

List<string> ids = doc.Descendants("pit").Elements().Where(k=>k.Attribute("Status").Value == "0").Select(i => i.Attribute("ExecutionID").Value).ToList();

Hope that helps.
