Rob, I came across the same problem when trying out various E4X approaches with delete. Steve's idea works (with the caveat his removes populated nodes instead of unpopulated ones, but I fixed that).

You can get an XMLList of all the empty nodes by this kind of statement xml.modules.module.(children().length() == 0); but if you then try a simple delete on that delete xml.modules.module.(children().length() == 0); you get: Delete operator is not supported with operand of type XMLList. I'm not sure right now why that wouldn't work. But you could simply loop through the XMLList generated and do a delete on each node var emptyModule:XMLList = xml.modules.module.(children().length() == 0); var index:int = emptyModule.length() - 1; for(var i = index; i > - 1; i--){ delete emptyModule[i]; } trace(xml); hth, Rob PS so as far as the delete operator I'm not sure why delete(xml.modules.module) works while something like delete(xm.modules.module.(@title == "apple")) gives an error like above. I would think that both those "querries" result in an XMLList, in the first case the delete occurs but not in the second... maybe some lunch will help my brain work better.
