Hi,

The way in which the xpath expressions would look like would depend on how the queried XML document structure looks like.
Maybe you should start reading some XPath tutorials:

https://www.w3schools.com/xml/xpath_intro.asp

and using Oxygen's XPath toolbar to test various small expressions on your XML instances.
