just a little elaboration on WSDigger
QUOTE
WSDigger is a free open source tool designed by Foundstone to automate black-box web services security testing (also known as penetration testing). WSDigger is more than a tool, it is a web services testing framework. Version one of this framework contains sample attack plug-ins for SQL injection, cross site scripting and XPATH injection attacks. A web service vulnerable to XPATH injection is provided as an example with the tool. By releasing the framework as an open-source tool, users are encouraged to develop and share their own plug-ins.
