have been able to significantly improve the contrib/xml XPath integration code. New features: * XPath set-returning function allows multiple results from an several XPath queries to be used as a virtual table. * Using libxslt, XSLT transformations (with and without parameters) are supported. (Caution: This support allows generic URL fetching from within the backend as well). I've removed the old code so that it is all libxml based. Rather than attach as a patch, I've put the tar.gz (10k!) at http://www.azuli.co.uk/pgxml-1.0.tar.gz (all files in archive are xml/....). I think this is worth replacing the contrib version with, even though the function names have changed (though the same functionality is there), because it includes a SRF and some SPI usage, in addition to linking to an external library. And it isn't a big module! Obviously, I understand that people might prefer to move it elsewhere, or might have reservations about replacing an existing contrib module with an incompatible one. I'm open to suggestions. John Gray
