Re: [flexcoders] RegExp multiple backreferences?

I think you should use g (global) flag in your regexp.

 private var headerBackreference:RegExp = /H([123]).*?\/H\1/;
 private function init():void {
 var s:String = BODYH2Valid Chocolate/H2 H2Valid
 Vanilla/H2 H2Invalid HTML/H3/BODY;
 var a:Array = headerBackreference.exec(s) as Array;
 if(a != null) {
 for(var i:int = 0; ia.length; i++) {
 trace(a[i]);
 }
 }
 a = s.match(headerBackreference);
 if(a != null) {
 for(var i:int = 0; ia.length; i++) {
 trace(a[i]);
 }
 }
 }

 I'm just trying to determine whether in fact this should return both
 the chocolate and the vanilla, or whether the behavior I see,
 returning just chocolate, is accurate. Thanks,
