Getting default value of an attribute from the DTD file

[Alexander (archive)]

Please, excuse me if the question is a basic one but I have not found any hint neither on XML4C samples, nor on Apache site. I'm using XML4C. I'm parsing an xml file and I'm getting to an attribute which is not explicitly specified in the xml file. The parser brings me its default value specified in DTD (if any) as the attribute's value.

The question is: How do I get the default value if the attribute explicitly appears in the xml file with some value?

Any help will be greatly appreciated. TIA.
