you can use the example from Microsoft - for you without namespace   using System Xml Linq  using System Xml XPath  var e   xdoc XPathSelectElement    Report ReportInfo Name           should do it

If you have XDocument it is easier to use LINQ-to-XML   var document   XDocument Load fileName   var name   document Descendants XName Get  Name     http   demo com 2011 demo-schema    First   Value    If you are sure that XPath is the only solution you need   using System Xml XPath   var document   XDocument Load fileName   var namespaceManager   new XmlNamespaceManager new NameTable     namespaceManager AddNamespace  empty    http   demo com 2011 demo-schema    var name   document XPathSelectElement   empty Report empty ReportInfo empty Name   namespaceManager  Value

XPath 1 0  which is what MS implements  does not have the idea of a default namespace   So try this   XDocument xdoc   XDocument Load   C  SampleXML xml    XmlNamespaceManager xnm   new XmlNamespaceManager new NameTable      xnm AddNamespace  x    http   demo com 2011 demo-schema    Console WriteLine xdoc XPathSelectElement   x Report x ReportInfo x Name   xnm     null
