Hi

Thx, Tom...
But isn't the libxml2 library not sufficient for this purpose? Note that I have not tried it yet, I am still just investigating possible solutions.
Unfortunately, no, or it is not about Postgres. The development of libxml2 is frozen :-/ and there are only bugfix releases. What I know, there are only some experimental enhancements, but nobody has finalized it.
XPath 2.0 is much more complex than XPath - it is a new language.
Please, don't send top post mails to this mailing list

I don't know of anyone actively working on that. The difficulty is
that we don't especially want to write/maintain such logic ourselves,
but there don't seem to be any suitable libraries available that
(a) can be called from C and (b) have a compatible license.
