I would like to get a list of items in the list (that is of items matched by the r'("[\w\s]+"|\w+)' part. So, for example >>> parse('foo "bar ...

I find the class Regex in .net extremely useful (for both matching and matching/replacing). There are some patterns that cannot be specified in regular expressions, but rather need a little grammar. Is there a library for parsers that DO NOT require code generation (like ANTLR)... but where I can specify the syntax in my code on the fly?...
Hi I have to parse a big HTML file, and Im only interested in a small section (a table).

As a purely academic exercise, I'm writing a recursive descent parser from scratch -- without using ANTLR or lex/yacc. I'm writing a simple function which converts math expressions into their equivalent AST. I have the following: // grammar type expr = | Lit of float | Add of expr * expr | Mul of expr * expr | Div of ex...

Hello, I was trying to use an abstract syntax tree in a bison parser, so I tried to use %union directive. Grammar file looks like this: %{ #include "compiler.h" #include "ast.h" #include "common.h" static bool verbose = true; extern "C" { int cyylex(void); void cyyerror(const char *s); } %} %union { ast_node *node; ...
Hello I am using preg_match to parse for data, it works 99% of the time but sometimes it gives me a result like: $match[1] = <a href="example">text i want</a> when what I really want is the "text i want" string. I am looping preg match and 99% of the time $match[1] gives me the text string i want but I want to implement something into...
