>I need to create an XML file by typing the content from a book that I follow. The XML is somewhat involved. I am using a Notepad to type in the content (if you have better suggestions that don't involve learning complicated tools, please let me know). But I also want to be sure that once I am done entering the content I didn't make a typo somewhere. How can I validate this XML file?

Check http://download.cnet.com/XmlPad/3000-7241_4-10252051.html to use instead of Notepad.

Though it doesn't say that Vista or Windows 7 are supported.
