Schema validation

[Andrea Bernicchia]

I have tried to use setExternalNoNamespaceSchemaLocation()/setExternalSchemaLocation() DOMParser methods, but they seems to work differently.   The first one seems not working, by comparison with the setExternalSchemaLocation(), which does.   When I set a different schema location using setExternalNoNamespaceSchemaLocation(), the parser seems to not looking for that file, conversely it continues to look for that one specified into the XML file.   What is wrong ?   Second question: Is it possible to set a schema loading it from memory and not from a file ?     Currently I am using xerces-c-1.7.0 under VC 7.1.   Thanks in advance
