XSLT function to get xpath to a node

Question

I need a XSLT function which will return me the xpath to the node from which it called.

XML

Answer 1

One reason that there's no standard function is that people want the path for different reasons:

Sometimes a/b/c/d is enough.

Some people want a[3]/b[5]/c[1]/d[2].

Some people want a path where the names don't contain namespace prefixes, so it has to be something like

*:a[namespace-uri()='abc']/*:b[namespace-uri='xyz'] etc.
