"\n"; but I can't get any results. I'm specifically interested in getting the ID value which would be 549592189 in this

问题 $xml = simplexml_load_file($xmlPath); $items = $xml->list->item; ... echo $items[$currentIndex]->asXML(); When I print out $currentIndex on each iteration, I get 0, 1, 2, 3, 4, etc. When I hard code $items[0]->asXML(); $items[1]->asXML(); $items[2]->asXML(); etc. I get the data I want. But when I loop like I do in the first code segment, it prints out items 0, 2, 4, etc. How is that possible and what could be causing this? Thanks, Ryan ADDED INFO: This is the main part of it: $totalItems = 45

问题 I hope you can help me on this one: I want to delete an xml node via unset. I have two variants of how this could be done, but only one is working.
