<?php
$n = new DOMDocument();
$n->loadHTML('<p>Thats a good example :/ .. with a <a href="http://www.foobar.com">link</a> inside.</p>');
$x = new DOMXPath($n);
$instances = $x->query('//text()[contains(.,\':/\')]');//or use '//*[child::text()]' for all textnodes
foreach($instances as $node){
    if($node instanceof DOMText && preg_match_all('/:\//',$node->wholeText,$matches,PREG_OFFSET_CAPTURE|PREG_SET_ORDER)){
            foreach($matches[0] as $match){
                    $newnode = $node->splitText($match[1]);
                    $newnode->replaceData(0,strlen($match[0]),'');
                    $img = $n->createElement('img');
                    $img->setAttribute('src','smily.gif');
                    $img = $newnode->parentNode->insertBefore($img,$newnode);
