Creating Payloads
You can use any text editor, such as Windows Notepad or WordPad to create your payloads.
Depending on your expertise, a dedicated XML editor, such as Microsoft XML Notepad or
XMLSpy may be easier to use and more appropriate if you are working extensively with
payload creation and maintenance. XML Notepad is a free download from Microsoft Corp.
XMLSpy is marketed by Altova, Inc. A 30-day evaluation version is available as a
download from http://www.xmlspy.com/download.html
