I realise that it does that! Unfortunately Zope's dtml isn't HTML.

Which parser should one use to analyse dtml which can contain tags like
<dtml-var standard_html_header>?

The above analysis won't work easily if I have <tag X> as then I'm
presented with attribute 'x' having value 'X'.

I merely want to copy the input to the output whilst making some trivial
changes to the URL's in <A href=URL> style tags. I guess I need to write
my own parser that doesn't make unnecessary assumptions.
