[xsd-users] Q: schemaLocation in schema file

[Rangarajan, Ravi_Sowmian]

Hi Boris,
Excellent analysis and behavior of the parser was very well explained. Now options are quite clear to me.
Thanks so much
Ravi

Overriding schemaLocation doesn't help in this case since the parser still validates (and then ignores) this attribute's content which should be a sequence of namespace/path pairs. To put it another way, according to the XML Schema spec, the document that contains mal- formed schemaLocation attribute is invalid.

If you are sure that the documents you will be parsing are valid (except for the schemaLocation attribute as mentioned above), then disabling validation should be ok. The only other approach that I can think of is to pre-process the XML document and remove the schemaLocation attribute altogether.
