PHP: documentElement->childNodes warning
- by jun
$xml = file_get_contents(example.com);
$dom = new DomDocument();
$dom->loadXML($xml);
$items = $dom->documentElement;
foreach($items->childNodes as $item) {
$childs = $item->childNodes;
foreach($childs as $i) {
echo $i->nodeValue . "<br />";
}
}
Now I get this warning in every 2nd foreach:
Warning: Invalid argument supplied for foreach() in file_example.php on line 14
Please help guys. Thanks!
