How to verify if an element is empty with XmlTextReader and IsEmptyElement?

Summary An example to check if the XML elelemt is empty or not.

What do I mean with an empty element? Simple, an empty element doesn't have a closing tag. These elements opens and closes in one tag. To close the tag you have to use / at the end of the tag. The following is an empty element. Notice the / at the end of the tag.

So how do you check whether this is an empty element or not with the XmlTextReader class? Luckily the XmlTextReader provides a property called IsEmptyElement. It will return true if it is an empty element and false if it isn't.

Additional information
<%@ import namespace="System.Xml" %> <%@ page language="C#" debug="true"%> <script runat="server"> void page_load(object sender, System.EventArgs e){ XmlTextReader xmlReader = new XmlTextReader(Server.MapPath("isempty.xml")); // Get rid of the first node which is <?xml version="1.0" encoding="ISO-8859-1"?> xmlReader.Read(); while(xmlReader.Read()) { if(xmlReader.IsEmptyElement) Response.Write("Empty element: "+xmlReader.Name +"/n"); } // Close the reader xmlReader.Close(); } </script>
