PHP simpleXML - foreach loop run
Question
Actually I'm stuck on running a foreach loop through a simple xml document. The document looks like this:
<outfits>
<outfit default="1" skin="0xFCDBBA" species="stud">
<head url="http://assets.zwinky.com/assets/stud/heads/01/head1" c="0xF2B38A" c2="0xffffff" z="33000"/>
<face url="http://assets.zwinky.com/assets/stud/faces/01/stud3" c="0x996633" c2="0xffffff" z="34000"/>
<midsection url="http://assets.zwinky.com/assets/stud/midsections/01/ms1" z="9000"/>
<leg url="http://assets.zwinky.com/assets/stud/legs/01/legs1" z="10000"/>
<hair url="http://assets.zwinky.com/assets/stud/hair/01/hr11" c="0x5C1C01" c2="0xffffff" z="37000"/>
</outfit>
</outfits>
So I kinda try to have each node as a single item.
My code:
$xml = simplexml_load_file($outfitUrl);
foreach($xml->outfit->children() as $item) {
echo $item;
}
Sadly nothing would show up.

The output of your code is as expected, because the nodes are empty
(though they have data stored inside attributes):
<leg url="http://assets.zwinky.com/assets/stud/legs/01/legs1" z="10000"/>
If it had a value, it would look like this, and it would be echoed by your code:
<leg url="http://someurl" z="10000">This is a node value.</leg>
If you want to retrieve the attributes of those nodes, you need a second foreach -loop:
$xml = simplexml_load_string($x); // assume XML in $x
foreach ($xml->outfit->children() as $item) {
// this loop will display all attributes of the current node:
foreach ($item->attributes() as $att => $attvalue)
echo "$att: $attvalue" . PHP_EOL;
}
see it working: https://eval.in/312473
If you know the names of the attributes you want, you can access them directly:
foreach ($xml->outfit->children() as $item) {
echo $item['url'] . PHP_EOL;
}
If you even know the nodes' names you want, you can go...
foreach ($xml->outfit as $outfit) {
echo $outfit['species'] . PHP_EOL;
echo $outfit->hair['url'] . PHP_EOL;
echo $outfit->face['url'] . PHP_EPÖ;
// etc.
}
