Question

I am trying to select all the child nodes of root node of an xml document using XPath query.

My xml file looks something like following :

Answer 1

Although the namespace in your XML document is fine, you need to use it in your SelectNodes. Use this code for your second XML:

XmlDocument gazetteDocument = new XmlDocument();
gazetteDocument.Load(xmlFilePath);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(gazetteDocument.NameTable);
nsmgr.AddNamespace("ns", "http://www.my_department.my_company.com/project_name");
XmlNodeList allNodes = gazetteDocument.SelectNodes("ns:root", nsmgr);

The better way would be to use XDocument and corresponding classes. They are a lot easier to work with.

Answer 2

You can use GetElementsByTagName method below are the snippet of my code

XmlDocument gazetteDocument = new XmlDocument();
gazetteDocument.Load(xmlFilePath);
XmlNodeList allNodes = gazetteDocument.GetElementsByTagName("root");

Answer 3

I don't know the old xml methods of C#, but you could always open the file to read as normal text, and then read to the first node and parse it however you like.
