Large File Schema Validation

All,

 

This may be a little off topic.

 

Currently we are working with very large XML datasets (meaning the file
is about 1GB in size), the file originally came from a csv file, which
was converted to xml, using some code that writes text (non-validated
schema).  Is anyone aware of any products that can do schema
verification using files this large? It's a little to big for XMLSpy.

 

Thanks,
