| + | ==About Regular Expressions == | ||
| + | A Regular Expression is a compact way of expressing patterns to search for and, optionally, a replace. It started life within Unix grep, but has now been implemented in many different technologies, for example: | ||
| + | |||
| + | Languages: AWK, Perl, Java, JavaScript | ||
| + | |||
| + | Text Editors: TextPad, UltraEdit | ||
| + | |||
| + | Over the years, there have been extensions to the Regular Expression syntax, but there is a core which all implementations accept. | ||
