Parsing XML with namespace using DOM

Question

XML is small and looks like below

<?xml version="1.0" encoding="UTF-8"?><userdetails xsi:schemaLocation="urn:MyNamespace loginasp.xsd" xmlns="urn:MyNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><username>909</username><password>madhuri1</password></userdetails>

For parsing this XML i have written the below code.

    XmlDocument doc = new XmlDocument();
                XmlDocument xDoc = new XmlDocument();
                xDoc.LoadXml(s);//S contains above XML
 XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());
                    nsmgr.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
 string emp_id = xDoc.SelectSingleNode("/userdetails/username", nsmgr).InnerText;

I am not able to select the single NODExDoc.SelectSingleNode("/userdetails/username", nsmgr) is null Is there any else i need to do to parse XML or My XML is wrong.Without namespace it works fine

That link doesn't actually answer the question although it is the same problem. It isn't to do with schemas, it's to do with changing the default namespace. — Steve

You need to add your default namespace into the XmlNamespaceManager.

nsmgr.AddNamespace("t", "urn:MyNamespace");

And then use this namespace in your XPath Query

string emp_id = xDoc.SelectSingleNode("/t:userdetails/t:username", nsmgr).InnerText;
