XML Formatting on Web Services Description Page

[CSharpTooth]

Does anybody know how to make a customized XML formatter like the one used
to display the SOAP request and response samples when you click on a Method
of a web service?

I am trying to debug xml coming back from a Web Service and need to display
the XML document inside of a <span> or <div> or <textarea> with the proper
formatting and indenting. The formatting under the Web Services description
page uses spaces or "&nbsp;" to indent the XML properly.

I couldn't find any samples on this.
