Capture SOAP attachments

Hi,

I used this link to setup a test step to capture the contents of a SOAP request and reply - which worked great:

viewtopic.php?p=16648#p16648

The only issue is that it only captures the XML -we would like to see the entire "stream" of data within the request and reply including the text file that is attached. Basically a "sniffer" type of capture. Any suggestions?

Thanks
