Linq to XML Parsing Help - getting elements?

Given the following:

- <ArrayOfWsParc开发者_如何学运维elDocIndexIAS xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
- <wsParcelDocIndexIAS>
  <locatorNum xmlns="http://xxx/webservices/wsDocumentIndex/">131312</locatorNum> 
  <docType xmlns="http://xxx/webservices/wsDocumentIndex/">KIOOLX_DOCINDEX</docType> 
  <docID xmlns="http://xxx/webservices/wsDocumentIndex/">234234</docID> 
  <docName xmlns="http://xxx/webservices/wsDocumentIndex/">Document - 7/1/2008</docName> 
  <fileExists xmlns="http://xxx/webservices/wsDocumentIndex/">true</fileExists> 
  <fileFormat xmlns="http://xxx/webservices/wsDocumentIndex/">PDF</fileFormat> 
  </wsParcelDocIndexIAS>
- <wsParcelDocIndexIAS>
  <locatorNum xmlns="http://xxx/webservices/wsDocumentIndex/">131312</locatorNum>

I'm trying to retrieve each element with

var documentElements = from docels in root.Elements("wsParcelDocIndexIAS") select docels;

Then

 foreach (XElement documentElement in documentElements)
            {
                XElement id = documentElement.Element("locatorNum");
                XElement file_type = documentElement.Element("fileFormat");

Yet when id and file_type are null with the syntax I'm using to try to get their values.

What am I doing wrong here?

Thanks

You're not specifying the namespace. Try this:

XNamespace ns = "http://xxx/webservices/wsDocumentIndex/";
foreach (XElement documentElement in documentElements)
{
    XElement id = documentElement.Element(ns + "locatorNum");
    XElement file_type = documentElement.Element(ns + "fileFormat");
    ...
}

The elements in the XML are in the namespace "http://xxx/webservices/wsDocumentIndex/", but the names you give to the Element method are not. You need to create an XName with the namespace and the name (there's an overloaded + operator for that):

XNamespace ns = "http://xxx/webservices/wsDocumentIndex/";
foreach (XElement documentElement in documentElements)
{
    XElement id = documentElement.Element(ns + "locatorNum");
    XElement file_type = documentElement.Element(ns + "fileFormat");
    // ...
