Description:
Extractvalue accepts XML fragments that are not wellformed. It was expected that this woud yield a runtime error or warning

How to repeat:

+-------------------------------+
| extractValue('<e>value','/e') |
+-------------------------------+
| value                         |
+-------------------------------+

Sorry, my comment should of course read:

only allow well-formed XML.

That is: please produce an error or warning when the XML is not well-formed.
