What are regular expressions used for?

Most regex features are already built into various programming languages, or they could be used via libraries if not. Regular expressions help make searches easier, a lot easier. Search engines improve tremendously with accurate use of regex, even if they are extremely large files. You can also use the search and replace tool, allowing you to make rapid changes across a great number of files. Another valuable source to use regular expressions in are text editors, giving you a wider access for data searching or modification.

How do regular expressions work?

Essentially, the first and main task of a regex processor is a translation. The processor translates the syntax form of a regular expression into a readable internal representation. This internal representation will then be able to be executed against a string or strings to be searched in.
