Can some one recommend a simple working example(code) of using recursive descent parser on haskell? All the information I found are too difficult to understand. Thx!

There's a chapter in, "Real World Haskell" devoted to Parsec, the recursive descent parser combinator library that comes with the Haskell Platform. There's also a bunch of Parsec links on the Haskell Wiki. Ultimately, once you get comfortable with the examples, you'll need the reference guide.

While not especially simple, Robert Giegerich's script for his lecture "Programmiersprachen und ihre Übersetzer" is a literate program featuring a recursive descent parser for (IIRC) a minimal Pascal with excellent documentation. In German, though, and not available on the net, but you can ask him directly.
