Extracting XML with PHP - php

Question

I know how to use simplexml_load_file to get XML results if the XML format is
<bowlcontents>
<banana>yellow</banana>
<apple>red</apple>
</bowlcontents>
However, I have some code that is in the format
<bowlcontents>
<fruit type="banana" skin="yellow" />
<fruit type="apple" skin="red" />
</bowlcontents>
and I want to manipulate it in the same way as in the first example. How would I do this?
EDIT: This is precisely what I want to do, yet the code below doesn't work.
<?php
$url = "http://worldsfirstfruitAPI.com/fruit.xml";
$xml = (simplexml_load_file($url));
$results = array();
foreach ($xml->bowlcontents->fruit as $fruit) {
$results[] = array(
$fruit['type'] => $fruit['skin'],
);
}
return $results;
}
?>
So at the end of it I would like to have an array, key=value:
banana=yellow
apple=red
...
I hope this clarifies. Thanks!

As per PHP's manual, attributes are accessed using the array notation:
$bowlcontents->fruit['type'];
Come to think of it, you didn't say in your question what was your problem. If that's about iterating over nodes, you can do it using foreach.
/*
$bowlcontents = simplexml_load_string(
'<bowlcontents>
<fruit type="banana" skin="yellow" />
<fruit type="apple" skin="red" />
</bowlcontents>'
);
*/
$url = "http://worldsfirstfruitAPI.com/fruit.xml";
$bowlcontents = simplexml_load_file($url);
foreach ($bowlcontents->fruit as $fruit)
{
echo $fruit['type'], "'s skin is ", $fruit['skin'], "<br/>\n";
}
