Regular Expressions (regex) are essentially a search engine for finding patterns in a text. While the syntax is a bit tricky to learn, regex will save tons of time and effort in the long run. Many of you are probably familiar with regex, even if only through the use of wildcards. Wildcard notation, such as <code>*.html</code>, matches to all html files in the given search directory. Regex takes this idea and expands on it dramatically, allowing for very complicated search patterns. A regular expression to find all html files in a given directory would be <code>.*\.html$</code> | Regular Expressions (regex) are essentially a search engine for finding patterns in a text.
