Wrap HTML with DIV until next H3

Answer 1

This is what it looks like after some nice (and dirty) jQuerying, to tidy up the HTML:

    
Serie 1000
    Model 1010
    Model 1020
    Model 1030
    Model 1040
    Model 1050

    
Serie 2000
    Model 2010

    
Serie 3000
    Model 3010

    
Serie 4000
    Model 4010
    Model 4020
    Model 4030
    Model 4040

In other words, all the other a elements disappear?

Then I run this jQuery script:

$('#subgr-productlist h3').each(function(){
    $(this).nextUntil('h3').wrapAll('
');
});

But that results in the #subgr-productlist div to render like this:

    
Serie 1000
    
Serie 2000
    
Serie 3000
    

        
    
    
Serie 4000
