A simple function that uses this method to print the nodes it finds in an xml document. Improvements welcomed.

<?php
function printTags($tag){

 
$node $this->doc->getElementsByTagName($tag);           
   for(
$c 0$c<$node->length$c++){
     
$text[$c] =$this->doc->saveXML($node->item($c));
     echo 
$text[$c];

   }

 
}
?>

Be aware that this function returns all descendants, not just immediate children.

Note that even though getElementsByTagName returns a NodeList which is defined as a list of DOMNodes, you're actually getting a list of DOMElements. That allows to call getElementsByTagName on each of the results.

$tables = $doc->getElementsByTagName('table');
foreach ($tables as $table) {
  $trs = $table->getElementsByTagName('tr');
  // etc...
}
