Select especific nodes in XML (Loop) - php

Question

I can't access only one node of an xml
<destinos>
<destino>
<programas>
<item>
<location>Spain</location>
...more content
</item>
<item>
<location>USA</location>
...more content
</item>
</programas>
</destino>
<destino>
<programas>
<item>
<location>France</location>
...more content
</item>
<item>
<location>Brasil</location>
...more content
</item>
</programas>
</destino>
</destinos>
I need:
<item>
<location>Spain</location>
...more content
</item>
<item>
<location>USA</location>
...more content
</item>
<item>
<location>France</location>
...more content
</item>
<item>
<location>Brasil</location>
...more content
</item>
i tried:
header('Content-Type: application/xml');
foreach ($xml->destinos->destino->programas as $resultado){
echo $resultado->asXML();
}
or
$xml = simplexml_load_string($string);
$items = $xml->xpath("//destino/programas");
header('Content-Type: application/xml');
foreach ($items as $personaje) {
echo $personaje->asXML();
}
But I only get the first two "item" of "program" or four elements but error in xml in the second example.
Thanks for the help, I have looked for solutions but I have not been able to find any that will help me solve this problem.

This is a bit of a fudge as it 'manually' adds in a root element. The main loop uses XPath to find all of the <item> tags and then just outputs the content.
header('Content-Type: application/xml');
$xml = simplexml_load_string($string);
echo "<root>";
foreach ($xml->xpath("//item") as $item){
echo $item->asXML();
}
echo "</root>";
