Meaningful error handling with Sax Parsers (Apache Xerces)

Question

Hello All,
I am using the Apache Xerces Parser 2.6.2 to parse some XML documents with a W3C XML Schema document.
My schema has a lot of rules enforced on the different elements and I was looking at some way to get userfriendly/meaningful prescriptive messages as output back to the user so that he/she can correct the errors in their XML files and have files conformant to the schema.
If I give an invalid XML file (with errors introduced by myself) the parser throws a SAXParseException with a message like ,
XML Document has Error: cvc-type.3.1.3: The value 'ANZc9901' of element 'uniqueid' is not valid. line number 6, column number 42
My XSD file
<xs:element name="uniqueid">
<xs:simpleType>
<xs:restriction base="xs:token">
<xs:pattern value="\s*ANZ[0-9]{4}\s*"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
My XML File's uniqueID element
<uniqueid>ANZc9901</uniqueid>
As you can see, the error message isn't of much use. I was looking at a way to handle them generically, and give out a suggestive error message based on the type of the error. Any help in this regard would be highly appreciated

well, it seems pretty obvious to me... Not sure how you are going to do a whole lot better.
