...but that's already inbuilt into the language - template matching.
That's 'the xslt way' of solving this problem.

A deep copy (xsl:copy-of) copies the entire subtree unmodified, so
that would be the wrong approach if you want the output tree to be
different to the input tree... but I agree that the identity template
and shallow copying etc takes a bit of understanding.  But when the
penny does drop, the genius of it all becomes clear.
