Alvaro Herrera 251cf2e27b Fix minor deficiencies in XMLTABLE, xpath(), xmlexists() ... Correctly process nodes of more types than previously. In some cases, nodes were being ignored (nothing was output); in other cases, trying to return them resulted in errors about unrecognized nodes. In yet other cases, necessary escaping (of XML special characters) was not being done. Fix all those (as far as the authors could find) and add regression tests cases verifying the new behavior. I (Álvaro) was of two minds about backpatching these changes. They do seem bugfixes that would benefit most users of the affected functions; but on the other hand it would change established behavior in minor releases, so it seems prudent not to.

Fixing that is a major undertaking, however.		2019-03-07 18:16:34 -03:00
