About Regular Expressions

Regular expressions allow you to perform very powerful and flexible string search
and replace operations. In traditional search and replace operations, as in the

for. This makes searches for dynamic data very difficult, if not impossible. For
example, how can you find the first occurrence in a string of any word that consists
entirely of capital letters that has spaces around it? Using regular expressions, the
task is trivial:
<cfset IndexOfOccurrence=REFind(" [A-Z]+ ","Some BIG string")>
<!--- The value of IndexOfOccurrence is 5 --->
You often process large amounts of dynamic textual data. Regular expressions can be
invaluable in writing complex ColdFusion applications.
You can use the case-insensitive functions,
expressions where the search string is likely to be mixed case.
