It's impressive that wxpath does the DSL as an extension of XPath syntax. I hadn't quite thought of it that way. I routinely used a mix of XPath and arbitrary code heavily for Web scraping (as implied in the intro for "https://docs.racket-lang.org/html-parsing/ https://docs.racket-lang.org/html-parsing/"). Then I made some DSLs for doing some of the common scraping coding patterns more concisely and declaratively, but the DSLs ended up in a Lisp-y syntax, not looking like XPath.
