>> What I need it to target a specific sequence of nodes. You can do that with my function as well - just pass in the sequence you want to target.

(I also tried casting levelXML as a wildcard with the same result: null.) Regarding Jason's code, private function countItems(xmlNode:XML):void { var total:int = 0; var xmlChildren:XMLList = xmlNode.children(); if(xmlChildren.length() > 0) { for each (var xmlNode:XML in xmlChildren) { total++; countItems(xmlNode); //The recursive call } } trace("totalItems2: ", total); } it doesn't do what I need. What I need it to target a specific sequence of nodes. Let's suppose I have the following xml: <data> <item> <label><![CDATA[Bracelets]]></label> <item> <label><![CDATA[Hook Bracelets]]></label> <item> <label><![CDATA[one]]></label> </item> <item> <label><![CDATA[two]]></label> <item> <label><![CDATA[three]]></label> </item> </item> </item> </data> Perhaps it would clarify things to state I'm building a drop-down menu. So the client mouses over "Bracelets". Out pops "Hook Bracelets". She mouses over that and out pops "one" and "two". In order to accomplish this, I need to discover which node is being moused over, in this case: item[0].item[0] but clearly it could just as easily be: item[46].item[27] and I could care less about the rest of the tree. Having said as much, my revised code: var x:*; x = xml.menu.item[whichItems[0]]; var levelsLeft:int = level - 2; var q:int; while(levelsLeft--) { q++; x = x.item[whichItems[q]]; } trace('xxx', x.item.length()); does, in fact, appear to work :)) Thanks again, John _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders ---------------------------------------------------------------------- This message w/attachments (message) is intended solely for the use of the intended recipient(s) and may contain information that is privileged, confidential or proprietary.
