Careful : getElementsByTagName will yield all elements with the given tag name under the present node, at any sub-level (i.e. among child nodes and all other descendant nodes)

I don't know if this is that obvious but it was not for me, so in addition to gem at rellim dot com's posting:

adding 



<?php

echo $param -> nodeValue.'<br>';

?>



to the loop will output

value1

value2

value3

Here is an example of getElementsByTagName():



<?php

$xml =<<<EOT

<?xml version="1.0"?>

<config>

  <section id="section1">

   <param name="param1">value1</param>

   <param name="param2">value2</param>

  </section>

  <section id="section2">

   <param name="param3">value3</param>

  </section>

</config>

EOT;



$dom = new DomDocument;

$dom->preserveWhiteSpace = FALSE;

$dom->loadXML($xml);

$params = $dom->getElementsByTagName('param');



foreach ($params as $param) {

       echo $param -> getAttribute('name').'<br>';

}

?>



Expected result:

--------------

param1

param2

param3
