I was dealing with SOAP tests a lot last month, and WireShark is little too much for simply checking a SOAP request. So I made a little script to show (not capture) the package content. It might be helpful if one needs automated SOAP testing as well. It’s very tiny (26 lines if use without Gzip) and doesn’t depend on any other modules.
