Regular expressions are used widely in computer programming, allowing people to search through many lines of code for a specific piece of data or find a very specific and precise set of information that would otherwise take them many hours of searching and sifting.
At Qualaroo, we use regular expressions (shortened to regex and regexes) to allow you to target your surveys to a specific set of pages, or to URLs that are complex or dynamic.
There's a lot of information about regexes on the internet, and a lot of it isn't really applicable to how you'll be using them at Qualaroo, so we've created this guide to Regexes for URL Targeting to help you get started.
We'll cover the following topics:
- The Regular Expression Interface
- Regular Expression Basic Characters
- Backslash - Escape!
- Question Mark - Not Required
- Digits and Word Characters
- Dot-Star: Anything Goes!
- The Or Pipe - Smoke 'em If You Got 'em
- Using Parentheses, Brackets and Sets
- Lookahead Delimiters
- More Resources
