I'm trying to use the XPath functionality of Postgres.
I can populate a text field (unparsed) with XML data but as far as I can see the xpath() function [now] only works on the xml data type.
When I try to populate a text field with XML data containing a DTD, however, the parser chokes. If I strip the DTD the parser chokes on undefined entities which are defined in the DTD.
(I switched the app' to from MySQL to Postgres because while MySQL works it returns matches in undelimited form which is next to useless if, for example, you return multiple attributes from a node.)
