Me too.  I saw that this is a pretty generic problem, so I tried to
create a reusable library called tagstack.  This just maintains a
stack of elements, and collects all the chardata for each tag into a
single zero-terminated string.  Like Expat, it provides two callbacks,
one for open tag, and one for close.  It doesn't need a chardata
callback, though, because it handles that internally all by itself.

It's still very much a work in progress -- I haven't even written a
full client for tagstack yet.  But the absurdly simple demo works.
You can find what I've done at

I hope to have it useful in a week or two.  I'd be interested in any
comments on my design of tagstack and its use of Expat.

It seems pretty complex.  It breaks on a lot of CRs, and some whitespace,
but it's hard to say exactly what.  Just rely on it possibly breaking
anywhere.
