PHP, XML How to get attributes?

Question

I am trying to return the values of the SECTION attribute of the INTRO tags from the following xml:

Sample of myxml.xml:

<INTRO SECTION="ONE">
  <TEXT>Hello</TEXT>
</INTRO>
<INTRO SECTION="TWO">
  <TEXT>Goodbye</TEXT>
</INTRO>

My PHP:

$doc = new DOMDocument();
$doc->load('myxml.xml');
$intros = $doc->getElementsByTagName("INTRO");

foreach( $intros as $intro ) {
echo $intro ->get_attribute('SECTION');
}

I am getting the following error:

Call to undefined method DOMElement::get_attribute()

Does anyone know what I am doing wrong? Kind regards to any responders.

DOMElement::getAttribute()

$intro ->getAttribute('SECTION');

Thanks @KingCrunch... getAttribute not get_attribute... I was getting confused because of the following link... php.net/manual/en/function.domelement-get-attribute.php... thanks.

DOM and DOM XML (PHP4) are two separate extensions. See php.net/refs.xml

try this:

  $xml = simplexml_load_file($file);
   ....
  $attr=$intro->attributes();
  echo $attr['SECTION'];

Thanks for the response, but I am getting the following error: Call to undefined method DOMElement::attributes() .... Do you think there is something incorrectly set up in my PHP?

5.3... however KingCrunch has answered it... should be getAttribute not get_attribute...I was getting confused because of the following link... php.net/manual/en/function.domelement-get-attribute.php... Thanks for your help though, much appreciated... J

KingCrunch is right as you can see in your link, it says use getAttribute for php 5 otherwise I use ->attributes() recently and it works fine. it give you a array with all attributes then you only have to get what you want $attr['attribute_name']

@Xenione You are talking about SimpleXML (php.net/simplexmlelement.attributes), one more XML extension. That's slightly independent from the PHP-version ... See php.net/refs.xml too

ok, of course I forget that you have to use $xml = simplexml_load_file('myxml.xml') before; I recommmend that, the file become a php object so it's really easy to use.
