Hi, in 8.3.3 Documentation / F.34.Xml2 the Deprecation notice claims: "..the core server now covers XML syntax checking and XPath queries, which is what Xml2 does, and more."
I can't get boolean values out from function "xpath". I think there is a missing implementation of xpath syntax.
Try for example: select xpath('false()',xml('<root/>')); select xpath('1=1',xml('<root/>')); select xpath('boolean(WHATEVERYOUWANT)',xml('<root/>'));
We have to keep in mind that xpath queries can return 4 value types: integer, string, boolean and nodeset. The previous Xml2 implementation was way more comfortable (functions: xpath_number, xpath_string, xpath_bool and xpath_nodeset).
