I think I have found a solution, using "element-content-whitespace" set to
false. Based on my existing code derived from O'Reilly Java and XML edition
3, I set the "element-content-whitespace" parameter to false on the
DOMConfiguration instance.
The code fragment from a method below is used for parsing different XML
Documents - i.e. different DTDs which means for some,
"element-content-whitespace" being false may be unnecessary and in fact
possibly change their data undesirably. I most cases I don't want text
elements to have their enclosed data cropped. So I provide it as a flag
option to turn on or off.
I only need to ignore whitespace for a certain XML Document type where I
need to compare just the elements, attributes child elements of these
Documents - for more detail on this see my response to you after the code
below...
// existing code
DOMConfiguration config;
DOMImplementationRegistry registry;
DOMImplementationLS lsImpl;
LSParser parser;
registry =
DOMImplementationRegistry.newInstance( );
lsImpl =
(DOMImplementationLS)registry.getDOMImplementation("LS");
parser =
lsImpl.createLSParser(DOMImplementationLS.MODE_SYNCHRONOUS,
null);
// Set options on the parser
config = parser.getDomConfig( );
config.setParameter("validate", Boolean.TRUE);
config.setParameter("error-handler", aDomErrorHandler );
// end existing code
// additional code
if ( ignoreWhitespace )
{
config.setParameter("element-content-whitespace", Boolean.FALSE);
}

My particular xml Document doesn't care about whitespace at all, it doesn't
have any enclosing elements like <text>....</text> which could contain
whitespace. All I'm interested in is the elements themselves, their
attributes enclosed within the < and /> and their child elements.

A have a DTD defined so I can use these.
The XML document is custom bespoke designed by me for a particular purpose
and I have used the utilities from net.sourceforge.saxon to generate the DTD
from the XML document.
