PHP xpath result as array of strings - php

Question

I have seen several similar questions, but not found the exact answer I'm looking for. It may be that the functionality I am looking for does not exist.
If I do an xpath query that results in an array of objects, but each object only holds one value, a string, I'd like to quickly convert that into an array of strings. Obviously I can do a foreach on the object and push the string value onto a new array, but if there is a built in function I'm not thinking of, please let me know.
example:
array(3) {
[0]=>
object(SimpleXMLElement)#24 (1) {
[0]=>
string(20) "Network Media Player"
}
[1]=>
object(SimpleXMLElement)#25 (1) {
[0]=>
string(12) "Music Player"
}
[2]=>
object(SimpleXMLElement)#26 (1) {
[0]=>
string(8) "Juke Box"
}
}
I'd like that to become
array('Network Media Player','Music Player','Juke Box')

Answer 1

Here's my test :
<pre><?php
$xml = "<data>
<item>
<value>Network Media Player</value>
</item>
<item>
<value>Music Player</value>
</item>
<item>
<value>Jukebox Player</value>
</item>
</data>";
$sx = simplexml_load_string($xml);
print_r($sx);
print_r(explode("|",implode("|",$sx->xpath("//data/item/value"))));
?></pre>
