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.

Answer 1

DOMElement::getAttribute()

$intro ->getAttribute('SECTION');
