I think you're trying to use parser combinators, of which Kotka is an implementation for Clojure.

If you're on the JVM Scala provides good support, though not very well documented, for parser combinators.

This is a very good introduction:

i don't know if this applies to Clojure but is a very easy reading about Monadic Parsing (asumes no Monads knowledge )

Actually, clojure.xml/parse runs a SAXParser instance and it's full of vars, (set!), (binding), etc.

I actually used that as the basis for a more namespace-aware parser that emits the XML token stream.

I could probably accomplish more of what I want in my parser, but I really want to isolate the non-functional, SAX-based portion and keep the rest pure Clojure, and I want the eventual token-to-tree parser to be truly functional. If I can wrap my head around the state and maybe monads, I think I'll have something.

Also it looks like the solution you feel most comfortable with, is similar (exactly?) how the clojure.xml parser works.

I haven't used it (indeed, I don't use Clojure) but it looks like the obvious way to parse in Clojure.
