xml.result, xml.test:
Adding test case.
item_xmlfunc.cc:
Fixed that Item_nodeset_func derived classes
didn't take into account charset of the XML value
and always worked using "binary" charset.
xml.result, xml.test:
Adding test case.
item_xmlfunc.cc:
Adding a special function to handle "self" axis.
Previously "child" and "self" were handled the same.
xml.result, xml.test:
Adding test case.
item_xmlfunc.cc:
Fixed that the "!" character written at the end was ignored.
Now if we try to scan "!=", and if "!" is not
followed by "=", we rollback lex scanner back
to "!" token, so the parser will start to check
the next rule from the "!" character again.
Previously parser started from the next character,
which was EOF in the example in xml.test,
which led to query being successfully parsed,
instead of producing a syntax error.
