I've been stuck on an interesting (IE: mind numbing) question for the past few hours. I've been trying to parse operators with regex: ([<>]=?|[!=]=) The ones that I want are: <= >= < > == != == and != matches great.

For example, if I had the following: word1 = what word2 = ...
Hi folks, i have the following regex pattern, which is used to strip out non, alpha-numerics. [^0-9A-Za-z] Works pretty good. I was hoping to mod this regex so it looks for alphanumerics AND spaces. How can i tweek it so it also accepts spaces? cheers :) ...
In PowerShell I find myself doing this kind of thing over and over again for matches: some-command | select-string '^(//[^#]*)' | %{some-other-command $_.matches[0].groups[1].value} So basically - run a command that generates lines of text, and for each line I want to run a command on a regex capture inside the line (if it matche...
Hi guys, i'm really not good with regular expressions and i need one to transform "1.2.3" to "1.02.03" in a way that first part stays always as it was and second and third one will transform 2 to 02, 7 to 07 and so on but if there is 10, 15, 17 and so on it will leave it as it is.

Hi, I need a regex to replace hyphens in the middle of any word but not to touch leading or trailing ones or standalone ones.

More specifically, what is the authoritative source for that information? This may look like a non-programming question, but I need to know whether a registry path fed to my code contains a regular expression or not. I decided the best way to do that is assume that any occurrence of an invalid character (like '*') means a wildcard searc...

I have read this question and several others, and they seem close, but I'm actually not looking for random data fulfilling a particular regex, I would like the set of all strings that m...
