Developing ColdFusion MX Applications with CFML

Chapter 7
Using Regular Expressions in Functions

Regular expressions let you perform string matching operations using ColdFusion functions. This chapter describes how regular expressions work with the following functions:

• REFind
• REFindNoCase
• REReplace
• REReplaceNoCase

This chapter does not apply to regular expressions used in the cfinput and cftextinput tags. These tags use JavaScript regular expressions, which have a slightly different syntax than ColdFusion regular expressions. For information on JavaScript regular expressions, see Chapter 27, "Building Dynamic Forms".
