Need a regular expression expert

[wiseduck]

I need a regular expression expert on this one.... I got this expression from
regexlib.com and am puzzled on how to convert it to work in CF. Anyone have
any Ideas?



(?:(?<protocol> http(?:s?)|ftp)(?:\:\/\/))
(?:(?<usrpwd>\w+\:\w+)(?:\@))?
(?<domain>[^/\r\n\:]+)?
(?<port>\:\d+)?
(?<path>(?:\/.*)*\/)?
(?<filename>.*?\.(?<ext>\w{2,4}))?
(?<qrystr>\??(?:\w+\=[^\#]+)(?:\&?\w+\=\w+)*)*
(?<bkmrk>\#.*)?

I would like to be able to create a match structure from the named elements in
this regex.....

mylink = structnew();
mylink.protocol = match
mylink.path = match ..... etc.

How about something like this:

<cfcomponent name="REMatcher">
<cfset This.EXPRS = StructNew () />
<cfset This.EXPRS.PROTOCOL = "(?:(?<protocol> http(?:s?)|ftp)(?:\:\/\/))"
/>
<cfset This.EXPRS.USRPWD = "(?:(?<usrpwd>\w+\:\w+)(?:\@))?" />
<cfset This.EXPRS.DOMAIN = "(?<domain>[^/\r\n\:]+)?" />
<cfset This.EXPRS.PORT = "(?<port>\:\d+)?" />
<cfset This.EXPRS.PATH = "(?<path>(?:\/.*)*\/)?" />
<cfset This.EXPRS.FILENAME = "(?<filename>.*?\.(?<ext>\w{2,4}))?" />
<cfset This.EXPRS.QRYSTR =
"(?<qrystr>\??(?:\w+\=[^\#]+)(?:\&?\w+\=\w+)*)*" />
<cfset This.EXPRS.BKMRK = "(?<bkmrk>\#.*)?" />

<cffunction name="Matches" returntype="boolean" access="public">
<cfargument name="Arg" type="string" required="yes" />
<cfargument name="Expr" type="string" required="yes" />
<cfset var result = REFind (Arguments.Expr, Arguments.Arg, "False") />
<cfreturn result />
</cffunction>
</cfcomponent>


<!--- Example. --->
<cfset str = "stringgoeshere" />
<cfset matcher = CreateObject ("Component", "REMatcher") />
<cfset mylink = StructNew () />
<cfset mylink.protocol = matcher.matches (Arg = str, Expr =
REMatcher.EXPRS.PROTOCOL) />
<cfset mylink.usrpwd = matcher.matches (Arg = str, Expr =
REMatcher.EXPRS.USRPWD) />
<cfset mylink.domain = matcher.matches (Arg = str, Expr =
REMatcher.EXPRS.DOMAIN) />
<cfset mylink.port = matcher.matches (Arg = str, Expr =
REMatcher.EXPRS.PORT) />
<cfset mylink.path = matcher.matches (Arg = str, Expr =
REMatcher.EXPRS.PATH) />
<cfset mylink.filename = matcher,matches (Arg = str, Expr =
REMatcher.EXPRS.FILENAME) />
<cfset mylink.qrystr = matcher.matches (Arg = str, Expr =
REMatcher.EXPRS.QRYSTR) />
<cfset mylink bkmrk = matcher.matches (Arg = str, Expr =
REMatcher.EXPRS.BKMRK) />
