What is a Regular Expression?

A regular expression is a sequence of characters that forms a search pattern. The search pattern can be used for text search and text replace operations.

When you search for data in a text, you can use this search pattern to describe what you are searching for. A regular expression can be a single character, or a more complicated pattern. Regular expressions can be used to perform all types of text search and text replace operations.
