It is written in Perl, using an XML/XSLT/XPath module I was using internally
for my programs. It is valid perl, except for some typos.

1) href is not in quotes because a word before => in perl can be used
without quotes. 
2) ../@code is not in quotes because I have made a typo.

Inside the call 'new Node', other nodes for the attribute and for character
data are created.

In a way similar to XSLT. Are you interested in implementation details?
