Using Regular Expressions in Functions

Regular expressions let you perform string matching operations using Adobe ColdFusion functions; in particular. regular expressions work with the following functions:

• REFind

• REFindNoCase

• REMatch

• REMatchNoCase

• REReplace

• REReplaceNoCase

Regular expressions used in the cfinput and cftextinput tags are JavaScript regular expressions, which have a slightly different syntax than ColdFusion regular expressions. For information on JavaScript regular expressions, see Building Dynamic Forms with cfform Tags.
