This looks very nice. Thanks.

earlier patches on the subject. This includes a data type with format
checking, and functions to mangle values. For the moment, I have cut
out the inessential stuff such as xpath. The included regression test
file xml.sql shows some of the things that work.

This patch already covers most of the parser work. What is left
hereafter is adjusting all the corner cases, the escaping rules, and
the various XML parser behaviors.

Use configure --with-libxml to build.

Here is an updated updated XML patch. Unless there are objections of
the sort that this approach is totally wrong or there is crash
potential, I'd like to get this committed this week and fill in the
gaps next year.

Great. The XML section of the datatypes documentation will need to be
updated. I can do that once you are done.

Peter - I have a few quick questions about the XML patch that you
submitted back in December.

Nikolay's original patch included support for XMLGEN(), but your patch
does not.

Are you planning to add XMLGEN() support? And if so, will it work
basically the same (from the user's perspective) as the XMLGEN() syntax
in Nikolay's patch?

Is there a problem lurking in XMLGEN() or is just something that you
haven't had a chance to complete?

Thanks.

Sorry, I meant XMLAGG() not XMLGEN()

The XMLAGG in Nikolay's patch didn't work right, so I removed it. If
someone wants to clean it up, please send a patch.

(Or maybe it did work right and I misjudged it, but it was mentally in
the way of all the other complications.)

And now that I have the name right, I found the answer:

Sorry to be a bother...
