Question

i am trying to parse an xml element (DItem >> Title)
below is my code but somehow i am not getting hold of it…. any help?

XDocument xdoc1 = XDocument.Load(url);
XNamespace ns = "http://sitename/items.xsd";
string topic = xdoc1.Descendants(ns + "DItem")
             .Select(x => (string)x.Attribute("Title"))
             .FirstOrDefault();

        <Item Id="28466" CatalogUrl="url">
          <DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title">
            <content:Source Acronym="ABC" OrganizationName="ABC" /> 
          </DItem>
        </Item>
      </Items>
    </content>
  </entry>
</root>

Using the namespace “http://www.namespace.xsd” should (and does) work:

XNamespace ns = "http://www.namespace.xsd";
string topic = xdoc1.Descendants(ns + "DItem")
                    .Select(x => (string)x.Attribute("Title"))
                    .FirstOrDefault();

Since DItem is not qualified with a namespace itself, it will use the default namespace specified asxmlns="http://www.namespace.xsd" on its parent element.
