Question

I have a very basic XML file that looks like this:

<allData>
  <allDataDetails>
    <quoteid>ABC123</quoteid>
    <customername>John Smith</customername>
  </allDataDetails>
  <allDataDetails>
    <quoteid>DEF456</quoteid>
    <customername>Jane Doe</customername>
  </allDataDetails>
</allData>

My XSD specifies that at least 1 allDataDetails element must exist. The doc is validated fine.

When querying using Linq to XML, though, I cannot seem to recognize or query for the inner elements within allData. Instead, when I view in the debugger, the Value attribute is all the data concatenated. It looks like this:

ABC123John SmithDEF456Jane Doe

Here’s my query code. myRows is always null, because I cannot seem to get the descendants:

XDocument entityXml = XDocument.Parse(myDataString);

var myRows = from d in entityXml.Descendants("allDataDetails")
             select new
             {
                quoteid = d.Element("quoteid").Value,
                customername = d.Element("customername").Value
             };

Anyone know what could be wrong here?

I just run your sample code, and few syntax error were fixed:
and also a comma for the value customer name was wrong, try my version below, it should work.

string myDataString = @"<allData>
                          <allDataDetails>
                            <quoteid>ABC123</quoteid>
                            <customername>John Smith</customername>

                          </allDataDetails>
                          <allDataDetails>
                            <quoteid>DEF456</quoteid>
                            <customername>Jane Doe</customername>

                          </allDataDetails>
                        </allData>";
             XDocument entityXml = XDocument.Parse(myDataString);


             var myRows = from d in entityXml.Descendants("allDataDetails")
                      select new
                        {
                            quoteid = d.Element("quoteid").Value
                            ,customername = d.Element("customername").Value
                        };
             foreach (var rw in myRows)
                 Console.WriteLine(rw.customername + "\t" + rw.quoteid);
