I'm terrible with regex, but I've had a try and a Google (and even looked in reddit's source) and I'm still stuck so here goes: My aim is to match the following 'codes' and replace them with the HTML tags. It's just the regex I'm stuck with. **bold text** _italic text_ ~hyperlink~ Here's my attempts at the bold one: ^\*\*([.^\*]+)\*...
I have a body of text that I have to scan and each line contains at least 2 and sometimes four parts of information.

I'd like to use a Regex parser to aid in some string processing in a C application. I'm ideally looking for something lightweight and open-source.

This is for .NET. IgnoreCase is set and MultiLine is NOT set. Usually I'm decent at regex, maybe I'm running low on caffeine...

I need to test for general URLs using any protocol (http, https, shttp, ftp, svn, mysql and things I don't know about). My first pass is this: \w+://(\w+\.)+[\w+](/[\w]+)(\?[-A-Z0-9+&@#/%=~_|!:,.;]*)? (PCRE and .NET so nothing to fancy) ...
