get attribute

[clankill3r]

I want to get the url in the [@attributes]

Atm i get the title like this

 

foreach ($xmlTree->channel->item as $item) {
    echo '<p>'.$item->title.'</p>';
}

 

i tried this

    $imageUrl = $item->enclosure->@attributes->url;
    print_r2($imageUrl);

 

but then i get this error:

Parse error: syntax error, unexpected '@', expecting T_STRING or T_VARIABLE or '{' or '$' in /

 

this is the XML:

                    [0] => SimpleXMLElement Object

                        (

                            [title] => #3315: Woord van het jaar: weigerambtenaar, Arabische lente tweede, plaszak derde

Have you tried to remove the @ sign?

[clankill3r]

yes no errors the, but neither a url.

Attributes is a function in SimpleXML, mate!

 

$imageUrl = (string)($item->enclosure->attributes()->url);

[clankill3r]

thanks mate!

 

How can i check if the atribute exists? In some cases it's not there and then i get:

 

Warning: main() [function.main]: Node no longer exists in /

[silkfire]

You check if the result exists:

 

if (isset($node->attributes()->attribute))

  [...]

[clankill3r]

I asume that in my case it would be

 

    if (isset($item->enclosure->attributes()->url)) {

 

but this produces still the warning

 

[clankill3r]

found it, i have to do it like this:

 

  if (isset($item->enclosure)){

    if (isset($item->enclosure->attributes()->url)){

$imageUrl = (string)($item->enclosure->attributes()->url);

}

    }
