Considering SimpleXML loads XML data using :

  • array keys for attributes
  • objects for values

Something like this should do the trick :

$string = <<<STR
<entry>
    ...
  </entry>
STR;

$xml = @simplexml_load_string($string);

echo (string)$xml->title . '<br />';
echo (string)$xml->link[1]->inline->feed->entry->author->name . '<br />';
echo (string)$xml->content->properties->Location . '<br />';
echo (string)$xml->link[1]->inline->feed->entry->content['src'] . '<br />';

And I get the following output :

Using var_dump($xml); can help you find out how your data is represented, when using SimpleXML -- makes things easier when it comes to accessing it ;-)


Note : here, I've used the @ operator to supress the warnings I was getting when using simplexml_load_string ; else, I have plenty of warnings like these :

Warning: simplexml_load_string() [function.simplexml-load-string]: 
   namespace error : Namespace prefix m on inline is not defined

Warning: simplexml_load_string() [function.simplexml-load-string]: <m:inline>

Maybe there's something that needs fixing, here ?
