Answer by 0SX for Parse only one item from RSS feed with PHP

I've figured it out:

$x=$xmlDoc->getElementsByTagName('item');$item_title=$x->item(0)->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;$item_link=$x->item(0)->getElementsByTagName('link')->item(0)->childNodes->item(0)->nodeValue;$item_desc=$x->item(0)->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;
