"... break that long line of E4X into separate components..." I am with you here. Do it one step at a time and check each step with a trace(xml.toXMLString()). If you really like concise, hard to read code, you can squash it back together once you get it working.

(For some reason people seem to want to write really long E4X statements - I'm not quite sure why...) Like this, your loop works. for each (var contentRowItem:XML in _contentXML..row) { var moduleName:String = contentRowItem.Module; var topicXML:XML = new XML("<topic />"); topicx...@title = contentRowItem.LinkTitle; // This e4x creates an XMLList, so pull off the first entry var module:XML=finalXML.module.(@title == moduleName)[0]; // Likewise var topics:XML=module..subsection.(@title==contentRowItem.Subsection).topics[0]; topics.appendChild(topicXML); } However - I'd include a bit of error checking for those XMLLists... for each (var contentRowItem:XML in _contentXML..row) { var moduleName:String = contentRowItem.Module; var topicXML:XML = new XML("<topic />"); topicx...@title = contentRowItem.LinkTitle; var modulesList:XMLList=finalXML.module.(@title == moduleName); if (modulesList.length()!=1) throw new Error("Can't find single module with title:"+moduleName); var topicsList:XMLList= modulesList[0]..subsection.(@title==contentRowItem.Subsection).topics; if (topicsList.length()!=1) throw new Error("Can't find single subsection with title:"+contentRowItem.Subsection); topicsList[0].appendChild(topicXML); } My general approach to this type of stuff is: break it down. Store and trace out each part of your e4x statement in a separate variable, bit by bit. That'll show you where it's going wrong.
