jQuery: wrapAll but separate sets of elements?

I have a somewhat grouping system which all the elements between two divs are grouped together. See the code below to see what I'm trying to say:

$(document).ready(function(){
var groupo = $('div').filter(function(){return $(this).text().match(/\[group\]/)}); //finds "[group]"
var groupc = $('div').filter(function(){return $(this).text().match(/\[\/group\]/)}); //finds "[/group]"
groupc.addClass("groupclose"); //adds the class groupclose so that it can be used by nextUntil
 groupo.nextUntil(".groupclose").wrapAll('<div class="group"></div>');
 groupo.remove();
 g开发者_Go百科roupc.remove();
});

When the HTML is:

<div>[group]</div>
<div>first</div>
<div>second</div>
<div>[/group]</div>

it works just fine, but when there are two or more 'groups' the wrapAll wraps them together, for example:

<div>[group]</div>
<div>first</div>
<div>second</div>
<div>[/group]</div>

<div>[group]</div>
<div>this is in</div>
<div>another group</div>
<div>which get wrapped together with the one above</div>
<div>[/group]</div>

The problem is similar to this wrapAll jQuery problem but in that case we know the number of divs in a set, while in this case we don't.

Any ideas?

I think you just needed to loop through the contents of groupo. Also, no need to use filter(). You can use the :contains('') selector

var groupo = $("div:contains('[group]')");
var groupc = $("div:contains('[/group]')").addClass("groupclose");

$(groupo).each(function(){
    $(this).nextUntil(".groupclose").wrapAll('<div class="group"></div>');
});

groupo.remove();
groupc.remove();
