public static java.lang.Object xpathHandlingIllegalChars(java.lang.String xml,
java.lang.String xpath)
Executes the given xpath on the given xml. If this fails becaues the xml is invalid
(e.g. contains ""), then it will attempt to escape such illegal characters
and try again. Note that the *escaped* values may be contained in the returned result!
The escaping used is the prefix "BR_UNICODE_"; if that string is already in the xml,
then it will replace that with "NOT_BR_UNICODE_".
