[xsd-users] Trying to generate a WSDL parser using xsd code synthesis

[Stefan Pantos]

Thanks for the pointer about initialzing xerces-C++.
 
After sending the second email I had another google and had found Q 2.1. I don't know how I missed it the first time. Sorry about that.

Thanks for the advice about parsing the xsd. Exactly what I was looking for. I'll have a look at libxsd.

Thanks once again,
Stefan
