Re: Converting from using scomp to SchemaTypeLoader.parse(...)

Ok, so I guess no one has ever tried this.

Maybe there's a simpler question:

If I use the SchemaTypeLoader.parse method, I struggle to get information
about the schema from that object. I want to iterate through the attributes
and elements declared in the XSD I'm parsing, but all I seem to get is w3
xml schema stuff. Am I trying to do something that isn't supported, or am I
just doing it wrong?

Any help much appreciated,

Cheers,

Badger.
