Test Your Regular Expressions in Real Time
If you’ve ever worked with regular expressions, you know how difficult and tedious it is to craft complex regex code. However, while it won’t work in every situation, REGex Tester, an online regular expression validator and testing tool, can help ease some the pain.
The site allows you to do a regex test, using JavaScript to instantly validate regular expressions. You can also put in a chunk of text to search and see live-updating results for any tweaks or changes you make to your regex pattern.
REGex Tester supports Perl (PCRE) and POSIX (PHP and more) regular expressions, but since most languages generally offer a POSIX or PCRE compatible mode, you should be able to test just about any pattern.
While regular expressions are complicated, they’re also one of the more powerful tools for searching and manipulating text. If you’ve never explored regular expressions before, be sure to take a look at our Regular Expressions Tutorial , which will get you started on the road to regular expression nirvana.
