I for one have used xmlstarlet in combination with grep for step 2,
which you could call from a cgi.  However, xmlstarlet is very slow,
especially for edit commands, where it loads the whole XML tree into
memory. Therefore if you just want to update a value, you'd rather write
your own perl script to do it.
