Trying to get property of non-object error handling

Question

most of the rss have an property call content:encoded, so I get it using this

//in a loop { $item_content=$x->item($i)->getElementsByTagName('encoded')->item(0)->nodeValue; }

but I also experienced error with some blogs that in its rss it doesn't have content:encoded property so I got an error of Trying to get property of non-object. How to I handle this?

You can use ->length property of the DOMNodelist before pointing out on that item:

$item_content = ''; if($x->item($i)->getElementsByTagName('encoded')->length > 0) { // if it exists, or at least one $item_content = $x->item($i)->getElementsByTagName('encoded')->item(0)->nodeValue; }
