mysql-test/r/xml.result:
- Adding test case
- Fixing error message
mysql-test/t/xml.test:
Adding test case
sql/item_xmlfunc.cc:
For grammar rules with loops like:
AdditiveExpr ::= MultiplicativeExpr ('+' MultiplicativeExpr)*
If we scanned scanned '+' and then met an error when parsing
MultiplicativeExpr, then we should fully stop parsing - without
trying to apply any other rules.
Fix: add "error" member into MY_XPATH structure,
and make my_xpath_parse_term() never return success
as soon as error set.
strings/xml.c:
Adding my_xml_ctype map for flags, indicating
whether a character is a space character, is a
valid identifier start character, is a valid
identifier body character. Using this map to
properly scan identifiers. Also, using this map
to scan spaces faster (instead of strchr).
