php xpath query on and xpath result

Question

Can I use an xpath query on a result already obtained using xpath?

Answer 1

In most hosting languages/environments (like XSLT, XQuery, DOM) you can. Don't know about PHP, but it would be strange if it doesn't allow this.

Of course, the result of the first query must be a node-set, in order for a future "/" operator to be possible/allowed/successful on it.
