Yes.

There will be indices if there are several siblings with the same name. In
this case there was just one item element.

What would the second step look like? I guess parsing will cause some pain
when there are indices. :( Anyhow, I was looking for a way (an easy way)
to transform the Path data into a document structure, since I need the
whole branch and not just a single element, which I would get if I applied
the (evaluated) XPath on the original document (e.g. copy-of). At least I
have not found a way yet to say: find this node/nodeset using this xpath
expression and then return the whole branch which leads to that
node/nodeset.

It's a component of a BPM software.
