Problem with SimpleXML

Question

I have the following xml code in my xml:

<features>
<pool type="inground">yes</pool>
<heating type="other"/>
</features>

However, if I do a print_r on my simplexml after parsing the xml, the pool element is set up like a string instead of the heating element which is an object. i.e

[pool] => yes
[heating] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [type] => other
                )

        )

And so the following code to get the type of the pool:

$type = $pool->attributes()->type

fails giving a fatal error -> member method on non object.

What's the solution here?

Thanks in advance.

echo $features->pool['type']; codepad.org/Eu1uMkgI

If you're looking to access the attributes of the pool tag, you need to descend to it first:

$s = '  <features>
    <pool type="inground">yes</pool>
    <heating type="other"/>
    </features>
';
$pool = simplexml_load_string($s);
var_dump($pool->pool->attributes()->type);

That seems to work; it returns this for me:

object(SimpleXMLElement)#3 (1) {
  [0]=>
  string(8) "inground"
}

i'd use this if it was an isolated case, but my xml is full of tags like this, i really don't want to manually do this on every tag of my xml...

Would this work if Pool was setup like <pool type='inground' /> too?

If you want to use current reading style. You have to use as bellow

$xmlLoad = file_get_contents($XML_FILE);
$xml = new SimpleXMLElement($xmlLoad);
echo $xml->features->heating->attributes()->type;

foreach ($pool->children() as $child)
{
  $type = (string) $child->attributes()->type;
}
