New XPath Extractor element supporting XPath 2 / Bug 60991

[UBIK LOAD PACK Support <su...@ubikloadpack.com>]

Hello,

UbikLoadPack Team is happy to contribute the enhancement desribed to Apache
JMeter developed by Thomas, Anthony and Philippe and sponsored by
Ubik-Ingenierie:

- https://bz.apache.org/bugzilla/show_bug.cgi?id=60991

Here are the enhancements:

- XPath 2 is now supported relying on SAXON9-HE under MPL 2 license
- A new element has been created to avoid any backward compatibility
constraint and to allow cleanup of code
- A new View Results Tree Renderer XPath2 Tester has been also implemented
- Performances of this component should be significantly faster than old
one as XPath Expression are now compiled and cached


We are happy to donate this code to Apache JMeter as we have already
donated other piece of code in the past under our signed CCLA.

Regards
UbikLoadPack Team
