Can you please add some more information to "cycle .... using stream-based
approach" ?
And - is it possible in XSLT to out some non-processed tags "as is", i.e.
not modifying their content, but just out the raw data ? I dont think so...
Hmm, I mean, when you proceed with XSLT, you cycle through the xml tags, but
you do not have control how the other tags being render, right ?
Take the example I've sent in the start - can you create xslt stylesheet to
do the things I've been talking about ? i.e. leaving all the document the
way it is, but replace some tags with another content ?
Thanx !
