I'm looking for a greedy RegEx match to replace all text in a number of HTML files between </title> and </head> (I've combined loads of JavaScript files to minimize the number of http requests). I've googled it but the majority of the solutions don't seem to work for me. (Which naturally leads me to assume that i'm wrong) This is my ...

In my answer to this question, I mentioned that we used UpperCamelCase parsing to get a description of an enum constant not decorated with a Description attribute, but it was naive, and it didn't work in all cases. I revisited it, and this is what I came up with: var result = Regex.Replace(camelCasedString, ...

Likewise, if the query is "stack overflow", then: "Stack Overflow is great." should become: "<b>Stack Overflow</b> is great." In other...

In learning Regular Expressions it had me wondering how the underlying engine works. Probably more specifically, I'd like to know more about how it evalutates, prioritizies and parses the expression. I feel the RegEx engine is a blackbox to me, and I would really enjoy deciphering it. So I'd like to ask if there are some great resourc...

I have a particular PHP page that I want to conditionally do things only if the visitor is not a search engine. Are there some good regex to match $_SERVER['HTTP_USER_AGENT']? Or would it be better to do a javascript redirect back to the page but set a flag, since search engines don't have javascript? (I don't have to worry much about m...
I am having trouble building a regular expression with the set of strings over {a, b, c} that is an odd length with exactly one a. Here is my best attempt so far: (bb|bc|cb|cc)*a(bb|bc|cb|cc)* This does good for even b and c on either side of the a, but does not account for a odd b and c combination on either side of the a. Any hint...
