Text replacement function for DOM.

<?php
function domTextReplace( $search, $replace, DOMNode &$domNode, $isRegEx = false ) {
  if (
$domNode->hasChildNodes() ) {
   
$children = array();
   
// since looping through a DOM being modified is a bad idea we prepare an array:
   
foreach ( $domNode->childNodes as $child ) {
     
$children[] = $child;
    }
    foreach (
$children as $child ) {
      if (
$child->nodeType === XML_TEXT_NODE ) {
       
$oldText = $child->wholeText;
        if (
$isRegEx ) {
         
$newText = preg_replace( $search, $replace, $oldText );
        } else {
         
$newText = str_replace( $search, $replace, $oldText );
        }
       
$newTextNode = $domNode->ownerDocument->createTextNode( $newText );
       
$domNode->replaceChild( $newTextNode, $child );
      } else {
       
domTextReplace( $search, $replace, $child, $isRegEx );
      }
    }
  }
}
