I am trying to parse some data to no success. Can anyone recommend a good introduction with a lot of examples to Recursive Descent Parsing? I haven't been able to find any.

I've recently being trying to teach myself how parsers (for languages/context-free grammars) work, and most of it seems to be making sense, except for one thing. I'm focusing my attention in particular on LL(k) grammars, for which the two main algorithms seem to be the LL parser (using stack/parse…

I'm building a custom expression parser and evaluator for production enviroment to provide a limited DSL to the users. The parser itself as the DSL, need to be simple. The parser is going to be built in an exotic language that doesn't support dynamic expression parsing nor has any parser generator…

I've got a BNF and EBNF for a grammar. The BNF is obviously more verbose. I have a fairly good idea as far as using the BNF to build a recursive-descent parser; there are many resources for this. I am having trouble finding resources to convert an EBNF to a recursive-descent parser. Is this because…

It's been a few years since my computer-language class and so I've forgotten the finer points of BNF's and EBNF's and I don't have a textbook next to me. Specifically, I've forgotten how to convert an EBNF into BNF.
From what little I remember, I know that one of the main points is to convert { term…

I'm creating a sophisticated JavaScript library for working with my company's server side framework.
The server side framework encodes its data to a simple XML format. There's no fancy namespacing or anything like that.
Ideally I'd like to parse all of the data in the browser as JSON. However, if…

To get an idea of what I'm doing, I am writing a python parser that will parse directx .x text files.
The problem I have deals with how the files are formatted. Although I'm writing it in python, I'm looking for general algorithms for dealing with this sort of parsing.
.x files define data using…
