Grab a copy of Tomi Vanek’s wsdl-viewer.xsl. Then use your favourite transformation tool. Yes, it’s that simple. I recommend xsltproc, the open-source command line XSLT processing tool, bundled with most Linux distributions, also used in soapUI. Windows fellas can get the binaries prepared by Igor Zlatković. Then simply type:
xsltproc -o the-wsdl-report.html wsdl-viewer.xsl your-wsdl-file.wsdl
