There is a similar question, but seems that solution didn't work out in my case Wierdness with XDocument, XPath and namespaces Here is the XML I am working with Demo Report Unit Test And below is the code that I thought it should be working but it didnt... XDocument xdoc = XDocument. Load(@"C:\SampleXML. Xml"); XmlNamespaceManager xnm = new XmlNamespaceManager(new NameTable()); xnm.

AddNamespace(String. Empty, "http://demo.com/2011/demo-schema"); Console. WriteLine(xdoc.

XPathSelectElement("/Report/ReportInfo/Name", xnm) == null); Anyone has any idea? Thanks. C# .net xml xpath xdocument link|improve this question edited Jun 4 '11 at 7:52Alex Aza16.5k52043 asked Jun 2 '11 at 2:40shrimpy1,16821237 77% accept rate.

If you have XDocument it is easier to use LINQ-to-XML: var document = XDocument. Load(fileName); var name = document. Descendants(XName.

Get("Name", @"demo.com/2011/demo-schema")).First(). Value; If you are sure that XPath is the only solution you need: var document = XDocument. Load("fileName"); // Added missing endquote.

It won't submit unless I type more. Var namespaceManager = new XmlNamespaceManager(new NameTable()); namespaceManager. AddNamespace("emtpy", "demo.com/2011/demo-schema"); var name = document.

XPathSelectElement("/emtpy:Report/emtpy:ReportInfo/emtpy:Name", namespaceManager).Value.

1 There was a missing endquote in there throwing off the syntax coloring. I added the quote, but it wouldn't let me submit without adding more, so I included the comment. Now it won't let me remove the extra comment.

Not sure how to fix that, sorry for the extraneous comment. – AaronM Jan 27 at 0:52.

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).

1 Your answer implies that XPath 2.0, in contrast of XPath 1.0 "*has" an idea" of a default namespace. I am not aware of such new XPath feature (we are talking XPath here, not XSLT or XQuery). Therefore, could you, please, explicitly mention in your answer what you are implying?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
