          Hardware: All
                OS: All

Description:
"FILTERXML Apply a XPath expression to a XML document."
While it does give a definition and example, XPath is a quite complex function
that is not obvious for those new to it. (I worked through a lot of different
errors before I got it working)
At the very least it should contain a link to more info about Xpath syntax,
like  https://www.w3schools.com/xml/xml_xpath.asp

Or even include a discription of the different elements like / // @ etc.

For a more advanced help page, maybe some of the Ask LibreOffice tips and
tricks could be combined?

Actual Results:

Expected Results:
info of how to use the function if you use it for the first time, or where to
get such info.
