Reading XML short notation value with PHP

Question

How do I get the value 1 with PHP and SimpleXML out of the following xml file?

data.xml

<users>
 <user name="test">
  <option name="enabled">1</option>
  <option name="setting">on</option>
 </user>
</users>

test.php

$file = 'data.xml';
$xml = simplexml_load_file($file);

foreach ($xml->users->user->option as $option) {
 echo $option['name'];
}

Output

enabledsetting

How do I output the value?

Take a look at the manual: http://php.net/manual/en/simplexml.examples-basic.php — IMSoP, Sep 16 '14 at 18:28

Possible solution without if or switch is using XPath :

$xml = new simplexml_load_file($file);
foreach ($xml->xpath('//option[@name="enabled"]') as $option) {
    echo $option;
}

Above XPath expression means, find all <option> nodes having attribute name value equals enabled.

Found the result:

test.php

$file = 'data.xml';
$xml = simplexml_load_file($file);

foreach ($user->option as $option) {
 if ((string) $option['name'] == 'enabled') {
  echo $option;
 }
}

Is there a solution to get it without "if" or "switch"?
