XML based programming language

[stefaan]

Hello,

I have recently had to deal with an XML-based
programming language. (The programs are
generated programmatically.)

XML leads to a "two-level" parsing problem: first
parse the xml into tokens, then parse the tokens
to grasp their meaning (based on the semantics
of the programming language).

Basically, I used elementtree as a sophisticated "lexer" and wrote a
recursive descent parser to perform the semantic analysis and
interpretation.
(It works great.)

But I keep wondering: do parser generator tools
exist that I could have used instead of writing
the recursive descent parser manually ?

Best regards,
Stefaan.
