    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 );
    }
    }
    }
    }
