Subject: [cfaussie] Re: RegEx Backreferences...
Something like this should do it for you:
<cfset regex = "(\d+)\s+(\d{4}\s+\d{4})">
<cfset str = "07 1234 5678">
<cfset stResult = reFindNoCase(regex,str,1,true)>
<cfdump var="#stResult#">
<cfset areacode = mid(str,stResult.pos[2],stResult.len[2])>
<cfset number = mid(str,stResult.pos[3],stResult.len[3])>
<cfoutput>(#areacode#) #number#</cfoutput>
If you return sub-expressions, the resulting structure will contain
multiple entries. The first element in the pos and len arrays will be
the match for the whole regex. The subsequent entries will be the
matches for the sub-expressions.
There should be n+1 entries in those arrays. Where n is the number of
sub-expressions in your regex.
