I'm looking at a regular expression in our source code, and I'm unsure if it's correct. <<SWE.[^<<]*>> Specifically, what does the [^<<] part do? I thought the brackets allowed you to supply a range.

It describes an alternative implementation of regular expressions that uses non-deterministic finite automatons (NFAs) versus deterministic ones (DFAs). It claims that back-tracking DFA implementations (t...
I must admit it's been a few years since my RegEx class and since then, I have done little with them. So I turn to the brain power of SO. . . I have an Excel spreadsheet (2007) with some data.
