 TechWizrd seems to be begging for a regex tutorial, so this is a thread for that. I don't have much time at the moment, so here's an example that matches a self-closing XML tag of the form <foo/> or <foo bar="baz" qux="quux"/> (the closing slash may or may not have whitespace before it, but not after):
Code:
 
selfclosing_tag_matcher = re.compile(r'<\w+(?:\s+\w+="(?:[^"\\]|\\.)*")*\s*/>')

Well, that looks complicated, but I need no tutorial. I learn by doing. That is why I am writing ArgueBot, a pseudo-intelligent chatbot. i suggest you try him. He is amusing at best... I am improving him, son he will have the ability to actually parse language. I am going to also write him in Spainish if I can...

ArgueBot was taken offline a while ago. I had started rewriting him to use natural language processing.

 Dude Bunny is such a more intuitive programming language yours is so totally lame and old and groady and fat. In Bunny, you use a 15fg interface terabite lightsaber module with 12 programming petaflops of floating binary points.
