The only whitespace reported that way is whitespace in element-only
content: that means that there has to be a DTD, and the DTD has to say 
that an element can contain only other elements.  This is a reporting
requirement for validating parsers from the XML 1.0 recommendation.

It's up to the application to decide whether to ignore the
whitespace.  A non-validating processor may report the same characters 
as regular character data.

You can use the same API for both, but any whitespace stripping must
be strictly at the application's discretion.


All the best,
