I agree it's not easy - 'what is the difference between xsl:copy and
xsl:copy-of?' is an interview question I use.

Once you can visualise the input xml as a tree of nodes in your mind
it's becomes straightforward, especially with attributes and their
values as a single node (you can't shallow copy an attribute and
change its value).  A shallow copy (xsl:copy) copies a single node to
the result (and just that node) while a deep copy (xsl:copy-of) copies
the whole subtree.

Lots of xslt is non-intuitive, but that doesn't mean it's
cumbersome... try doing the same task in any other language.


You are speaking as and to the cognoscenti only.
