My `txexpr` library has some higher-level utilities for working with complicated X-expressions. http://docs.racket-lang.org/txexpr/ <http://docs.racket-lang.org/txexpr/> Also see `pollen/decode`, which I designed for selective replacements within text-based X-expressions, but will work with any X-expression: http://docs.racket-lang.org/pollen/Decode.html?q=pollen%2Fdecode <http://docs.racket-lang.org/pollen/Decode.html?q=pollen/decode> > I suppose I could take a look at the XML string and do a regexp-match or > something similar, but that seems inelegant and almost brute-force-y.
