2.  $('p *',$(frame).contents()).each(function(){
3.     $('*',this).contents().add($(this).contents()).filter(function(){
4. return this.nodeType==3 && $.trim($(this).text()).length>0
5. }).each(function(){
6.             if(!($(this).parent()).hasClass('HL')){
7. var html=$(this).text();
8. var compare=$(this).text();
9. html=html.replace(new RegExp(text, "gi"),function(matched) {return "<span class='HL' style=background-color:#d2b0ff>" + matched + "</span>";});  
10. if(compare!=html){
11.  $(this).replaceWith(html);
12. }
13. }
15. })
16. });

But the words match when they are as a whole in a textnode. the problem is when I want to find a word like this:

the word is in a paragraph:

<p><span>wo</span><span>rd</span></p>
