Sorry to say, either it's HTML or it's not and bare anglebraces are
not HTML. There's no way to reliably tokenize only some angles without
serious context analysis, and even a reasonably complex regular
expression isn't going to be able to get EVERYTHING right. Your only
path that I see is to load a DTD and essentially pre-render the document
in memory to handle the real tags, convert everthing that's left to
entities, and then compare/build the two copies, taking the tags from
the raw file and the entities from the rendered-and-converted one. And
even that could screw things up at least differently from some other
means of rendering things, so results could vary.
