Learn – Test Regular Expressions With The Regulator
What is Regex?
A regular expression, often called a pattern, is an expression that describes a set of strings. They are usually used to give a concise description of a set, without having to list all elements. For example, the set containing the three strings "Handel", "Händel", and "Haendel" can be described by the pattern H(ä|ae?)ndel (or alternatively, it is said that the pattern matches each of the three strings) (via Wikipedia).
The Regulator is an advanced, free regular expressions testing and learning tool. It allows you to build and verify a regular expression against any text input, file or web, and displays matching, splitting or replacement results within an easy to understand, hierarchical tree.
Regex actions supported:
- Find multiple matches
- Replace text according to expression
- Split text according to expression
The Regulator is also integrated with RegexLib.com, a free regular expressions library, and helps finding ready-to-use regular expressions.
