Sax 'characters' method and ignoring Whitespace
Hi
I notice that when I am using the Sax parser, I receive the whitespace data
as well as the data contained in the element. How can I ignore the
whitespace or strip it out of the input data?
Thanks,
Bruce

The whitespace chars are only reported if you are using a validating parser. If
you use a non-validating parser, the spaces are returned via the characters()
callback.

At this point I am not using a DTD. The "missing" whitespace is not being
returned via the characters() or ignorableWhitespace() callbacks. Where
else can I look?

Its delivering them, you just probably aren't looking in the right place.
According to XML rules, if you are using a DTD and the element's content
model is CHILDREN style, then the whitespace is delivered as 'ignorable
whitespace'. If the content model allows character data, then its delivered
as 'characters'. So make sure you are handling both of those SAX APIs if you
are using a DTD.

I just noticed today that the SAX parser was NOT delivering white space that
was part of a text node element! And I need it! Maybe someone
knowledgeable can address this one.
