Re: XML-SAX *XML_EXCEPTION event and reported parsed length question

Hi Nathan,

An XML document can be comprised of multiple, identifiable sets of data.
In the presence of multiple sets of data, one would need to call XMLTABLE
once for each distinct set that required extraction. You're not going to
be able to use only a single call to XMLTABLE, unless only a single set of
data is contained within the hierarchy that required extraction.

That should hopefully make more sense now.

At least in the context of multiple sets of data, XMLTABLE is extracting an
entire set at a time, instead of the other techniques I'm vaguely familiar
with, where one extracts a single element at a time.

I'd be shocked if XMLTABLE, which uses a SET based approach, doesn't
perform faster.

I haven't used XMLTABLE yet. But I'm a little perplexed about mapping
hierarchically structured "documents" to "tables". Vern indicated that he
would be populating about 13 tables from apparently one XML document.
