Regular Expression Test

If you have a Regular Expression that you think should work, try entering the pattern into the first box and then a sample into the second and press the button to see, although in this one you don't need to have a / at the start or end of the pattern :

Regular Expression	Sample	Test
Check Entire Text Case Insensitive	Replace With :

Checking the 'Check Entire Text' box adds a /g to the Regular Expression and ticking the 'Case Insensitive' adds a /i

You can bookmark this page so you refer back to this page at any later date and try out any Regular Expressions that you are putting together.

Now that we have seen what a Regular Expression can do for you, we need to cover off some of limitations and things to be careful of when using Regular Expressions.
