with sample of code

  var xmlpath = "/feed/entry";       var xmldoc = new xmldocument();     var webclient = new webclient();     var stream = new memorystream(webclient.downloaddata("http://services.digg.com/2.0/story.gettopnews?type=rss"));     xmldoc.load(stream);       var mgr = new xmlnamespacemanager(xmldoc.nametable);     mgr.addnamespace("ns", "http://www.w3.org/2005/atom");       xmlnodelist xmlnode = xmldoc.selectnodes(xmlpath, mgr);      int count = xmlnode.count;      console.writeline("count : "+count);      //console.writeline(xmlnode.name + ": " + xmlnode.innertext);     console.readkey();

what i'am dogin wrong!?!? other problema i've how tag in different namespace 

<digg:category> technology </digg:category>

thaks

when call mgr.addnamespace("ns", "http://www.w3.org/2005/atom"), defines namespace prefix ns, can use in xpath query. but have use it:

var xmlpath = "/ns:feed/ns:entry";

although if you, use more descriptive prefix, atom, or a.
