Do you know a tool to easily visualize a wsdl file ?

[Samy Mechiri]

Hi everyone,
 
do you know any small, easily usable tool to visualize what operations
(and their arguments) are available on a wsd file ?
 
There seem to be nusoap having such a tool (i've read about it on
http://www.xml.com/lpt/a/1388) but I could not find any reference to it
on nusoap's web page.
 
Ideally it would output the results as a txt or html file
 
Thank you for reading.
