It won't choke on XHTML.

Not that I know of (google for it), but DOM is probably the easiest
way to make one.  DOM libraries often have a prettyprint function to
(textually) print DOM nodes (eg. 4DOM from PyXML), which I've found
quite useful -- but of course that's just a chunk of the HTML nicely
reformatted as XHTML.  Alternatively, you could use something like
graphviz / dot and some DOM-traversing code to make graphical trees.
Unfortunately, if this is HTML 'as deployed' (ie. unparseable junk),
you may have to run it through HTMLTidy before it goes into your DOM
parser (use mxTidy or uTidylib).
