Read nodes in XDocument

Question

Hello.  I've read a lot of tech docs but have been unsuccessful resolving my issue.

I am returned a string which I convert to XML, as follows:

<?xml version="1.0" encoding="UTF-8"?>
<MyType xmlns="http://myurl.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <myHeader>
    <HeaderElement1>
      <DateTime>2012-05-21T14:54:57-06:00</DateTime>
    </HeaderElement1>
    <HeaderElement2>
      <Value1>123</Value1>
    </HeaderElement2>
  </myHeader>
  <Response>
    <Status>
      <Node1>Hello</Node1> 
      <Node2>World</Node2>
      <AdditionalDetail>
        <Name>John Doe</Name>
      </AdditionalDetail>
    </Status>
  </Response>
</myType>

So far, I have been able to print out all the node names doing something like:

XDocument doc= XDocument.Parse(responsestring);
foreach( XElement xe in doc.Descendants())
  Console.WriteLine(xe.Name.ToString());

I get an answer like:
{http://myurl.com}MyType
{http://myurl.com}myHeader
...
{http://myurl.com}Response

So, I wanted to get all the node names and values under the Response section.

I tried this:

XDocument doc= XDocument.Parse(responsestring);
foreach ( XElement xe in doc.Descendants("{http://myurl.com}Response"))
   Console.WriteLine(xe.Name.ToString())

All I get back is '{http://myurl.com}Response'.

If I change it to Console.WriteLine(xe.Value.ToString()), I get all the values in one string like:

HelloWorldJohn Doe

I won't always get the same nodes so I'd like to get the node names and values individually.

Thank you very much!!

Hello, I don't know exactly what you want to achieve. If you want to parse all children of the Response element, you need to define a recursive method:

        private static void ParseChildElements(XElement parent)
        {
            foreach (XElement element in parent.Elements())
            {
                Console.Write(element.Name.LocalName + "\r\n");
                if (element.HasElements)
                {
                    // Do not print value. Instead, parse child elements.
                    ParseChildElements(element);
                }
                else
                {
                    Console.Write(element.Value + "\r\n");
                }
            }
        }

Then invoke it:

            XNamespace xNamespace = "http://myurl.com";
            XElement responseElement = doc.Descendants(xNamespace + "Response").First();
            ParseChildElements(responseElement);

Also note your question has nothing to do with WCF. If you have further questions, please post them on the LINQ forum: http://social.msdn.microsoft.com/Forums/en-US/linqprojectgeneral/threads
