What I would love -- possibly integrated into HTML Tidy -- would be a
more sophisticated configuration file for both, tree modification and
pretty printing. I thought about using XPath and CSS like syntax like

  @namespace url(http://www.w3.org/1999/xhtml);

  pre                      { white-space: pre }
  pre                      { break: break-before break-after }
  a[@name]                 { trim: no }
  p                        { trim: if-empty }
  p[preceding-sibling::h1] { indent: 2 }
  @*                       { trim: if-proprietary }
  ...

I think you get the idea. With a good set of properties it should be
quite simple to get exactly your favourite coding style, it would really
be a general purpose highly configurable XML tool. I thought about
integrating libxml with HTML Tidy to use its DOM instead of Tidy's, this
would ease writing APIs, we would have an XPath engine, DTD validation,
at some point XML Schema validation, ... lots of cool stuff. I don't
have the time, unfortunately. It should be quite simple though.
