Although this technique for static text to perform a simple search and replace tasks might be sufficient, but it lacks flexibility, the use of this method to search dynamic text, if not impossible, at least becomes very difficult. Regular expressions is a text-mode, including ordinary characters (for example, letters between the a to z) and special characters (called "metacharacters"). Describes one or more strings to match when searching for text. Regular expression structure with a structure similar to an arithmetic expression.

For example, a single-character pattern, such as a, regardless of where the searched string, it matches the letter a. Non-printing characters can be part of a regular expression. If you are unable to specify the number of characters that constitute a match, then regular expression supports the concept of a qualifier.
