Did you ask about XML::Xerces earlier?

The issue is that I couldn't find any appropriate parser in perl for this Job

I don't think there is one. Any compliant parser should do the job though. There are many parsers around, but only few are fully conformant. My one-stop solution is xerces. If you are willing to spend money there are excellent commercial parsers on the market. For the sake of clarity: you need a parser that fully supports the XMLSchema recommendation, anything else won't do.

When an attribute is declared with a default value in the schema and you parse/process the instance document, the value of the attribute returned by the parser will be:

• - if the instance document contains a value for the attribute this value is taken
• - else the default value as defined in the schema is taken

No need to use XSLT or anything.
