I don't know why but I just found out how useful rematch can be this week. The rematch function will take a regular expression, a string to search and then return to you an array of matches. In my case I was reading a file and searching for a specific string. Let's take a look at this example and just how useful it can be. The data is piece out of the template I was reading. The regular expression "{[^{]+}" will find the text between { and }. <html> <head> <title>reMatch Example</title> </head> <body> <cfsavecontent variable="data"> <:cfset this.name = "{appname}"> <:cfset this.sessionManagement = {sessionmanagement}> <:cfset this.sessionTimeout = createTimeSpan({sessiontimeout})> <:cfset this.applicationTimeout = createTimeSpan({applicationtimeout})> <:cfset this.setClientCookies = {setClientCookies}> <:cfset this.setDomainCookies = {setDomainCookies}> <:cfset this.clientStorage = {clientStorage}> <:cfset this.loginStorage = {loginStorage}> <:cfset this.scriptProtect = {scriptProtect}> <:cfset this.serverSideFormValidation = {serverSideFormValidation}> <:cfset this.secureJSON = {secureJSON}> <:cfset this.secureJSONPrefix = {secureJSONPrefix}> <:cfset this.smtpserver = {smtpserver}> <:cfset this.timeout = {timeout}> <:cfset this.debugipaddress = {debugipaddress}> <:cfset this.enablerobustexception = {enablerobustexception}> </cfsavecontent> <cfset properties = rematch("{[^{]+}",data)> <cfdump var="#properties#"> </body> </html>

Indeed! It is very handy and I only wish I knew about it earlier.

reMatch() is pretty awesome.

I see the usefulness of reMatch() as being fairly limited, given it doesn't support the return of matched subexpressions like reFind() does. It's pretty rare that I don't also want to match subexpressions when using regexes, and in not doing this, it's rendered useless for all except fairly basic situations.

It seems to me like it's a half-finished solution.

Still: something that's half-finished does have the scope to be finished one day, I guess.
