Summary How to create a navigator with XmlDocument and CreateNavigator?

A navigator is something that is used to navigate. In terms of XML it is used to iterate the XML file. The key is to use the function CreateNavigator. This function will return a XPathNavigator object which you can use to iterate or navigate through the XML file. In this example you will how you can create a navigator with the XmlDocument class to naviagate through a XML file. For that example I am using the following XML file.

Output:

1st news titledescription of the 1st news 2nd news titledescription of the 2nd news 3rd news titledescription of the 3rd news 4th news titledescription of the 4th news 5th news titledescription of the 5th news

Additional information

<%@ import namespace="System.Xml" %> <%@ import namespace="System.Xml.XPath"%> <%@ page language="C#" debug="true"%> <script runat="server"> void page_load(object sender, System.EventArgs e){ // Create a new XPathDocument object // and pass the filename as a parameter. XPathDocument xpathDoc; xpathDoc = new XPathDocument(Server.MapPath("XmlDocumentWithCreateNavigator.xml")); // Create a navigator from the XPathDocument XPathNavigator nav = xpathDoc.CreateNavigator(); // Select some nodes XPathNodeIterator nodeIterator = nav.Select("NewsList/News"); // Iterate through the nodes with the iterator while (nodeIterator.MoveNext()) { Response.Write(nodeIterator.Current+"/n"); } } </script>
