Question

Sorry if this seems like an easy question, but I’ve started pulling hair out on this…

I have a XML file which looks like this…

<VAR VarNum="90">
  <option>1</option>
</VAR>

I’m trying to get the VarNum.

So far I’ve been successful using the follow code to get the other information:

$xml=simplexml_load_file($file);
$option=$xml->option;

I just can’t get VarNum (the attribute value I think?)

Thanks!

You should be able to get this using SimpleXMLElement::attributes()

Try this:

$xml=simplexml_load_file($file);
foreach($xml->Var[0]->attributes() as $a => $b) {
    echo $a,'="',$b,"\"\n";
}

That will show you all the name/value attributes for the first foo element. It’s an associative array, so you can do this as well:

$attr = $xml->Var[0]->attributes();
echo $attr['VarNum'];
