I am looking for an XPath 2.0+ online checker not only for testing but also for saving and sharing - similar to online regex tester (like regex101.com) or online compiler sites (like ideone.com, rextester.com).
The idea here is to be able to have shareable samples, e.g. for Stack Overflow questions.
I found some XPath online checker, e.g. here A program / site paste some xml, submit some sort of xpath query and return a result, but none of them is shareable.
