Question

Given this XML …

<ListBucketResult xmlns='http://s3.amazonaws.com/doc/2006-03-01/'>  <Name>public.rpmware.com</Name>  <Prefix></Prefix>  <Marker></Marker>  <MaxKeys>1000</MaxKeys>  <IsTruncated>false</IsTruncated>  <Contents>   <Key>0.dir</Key>   <LastModified>2008-06-25T16:09:49.000Z</LastModified>   <ETag>'0ba2a466f9dfe225d7ae85277a99a976'</ETag>   <Size>16</Size>   <Owner>    <ID>1234</ID>    <DisplayName>kyle</DisplayName>   </Owner>   <StorageClass>STANDARD</StorageClass>  </Contents>  <!-- repeat similar 100x -->      </ListBucketResult> 

And this C# code:

XDocument doc =  XDocument.Load(xmlReader); var contents = from content in doc.Descendants('Contents') select new {Key = content.Element('Key').Value, ETag = content.Element('ETag').Value};          foreach (var content in contents)         {             Console.WriteLine(content.Key);             Console.WriteLine(content.ETag);         } 

I know the Xdoc is not empty and contains the right XML.

I also implemented some ScottGu code (http://weblogs.asp.net/scottgu/archive/2007/08/07/using-linq-to-xml-and-how-to-build-a-custom-rss-feed-reader-with-it.aspx) as a sanity check and it works exactly as expected.

XDocument doc2 = XDocument.Load(@'http://weblogs.asp.net/scottgu/rss.aspx');         var posts = from items in doc2.Descendants('item') select new { Title = items.Element('title').Value };         foreach (var post in posts)         {             Console.WriteLine(post.Title);         }

Xml namespaces:

    XNamespace ns = 'http://s3.amazonaws.com/doc/2006-03-01/';     var contents = from content in doc.Descendants(ns + 'Contents')                    select new { Key = content.Element(ns + 'Key').Value,                        ETag = content.Element(ns + 'ETag').Value };
