XSD Validator Question

A colleague is looking for an XSD validator which will provide a list or table of all the validation errors found in validating an XML file, rather than reporting only the first error like what XMLSpy will do.
 
In addition, we are not allowed to use online validation tools such as http://www.stg.brown.edu/service/xmlvalid/.
 
Any suggestions?
 
 
Thanks,
