How can I make a regex match the next 4 characters immediately after finding something?

Question

I'm trying to write a regex to sift through a sizable amount of data. After it finds something, I want it to match the next 4 characters whatever they are. How can I do this?

Answer 1

/match long stuff here..../

The . in a regex is "Any character." Four of them gets you four characters. You could also do:

/match long stuff here.{4}/

This may depend on what language you are writing your regex in.
