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 );
 }
 }
 }
}
