I've been trying to parse the wikitext of section 0 with a minimal
parser that uses just the tokens {{ }} {{{ and }}} but it already has
probems when it sees }}}}

The template and parameters I'm interested don't generate any such
external links and probably couldn't very easily...
But I have just discovered the rvgeneratexml parameter to
action=query&prop=revisions
This includes a <part> field for each template parameter with a <name>
and a <value> for each...
