Question

My question is, does the XPathSelectElement method support a where clause in the xpath query?

Here is an example of what I am trying to do:

var element = coreXml.XPathSelectElement(configuration/system.serviceModel/client/endpoint[@name='SomeService']);

When I run this I am returned ‘null’ based on the follow xml:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <client>
            <endpoint address="http://localhost:40901/SomeService/" binding="basicHttpBinding" contract="SomeContract" name="SomeService"/>
        </client>
    </system.serviceModel>
</configuration>

Regards.

I can’t reproduce the problem, I saved your XML samples as “XMLFile2.xml” in a C# console project, then corrected your code sample to wrap the XPath expression passed to XPathSelectElement in double quotes and made the following code sample:

    XDocument coreXml = XDocument.Load("../../XMLFile2.xml");
    var element = coreXml.XPathSelectElement("configuration/system.serviceModel/client/endpoint[@name='SomeService']");
    Console.WriteLine(element == null);

It outputs “False”.

So something in your real code is different.
