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 );
}
}
}
}
