html - I need to replace a div with another div using jQuery -

- 

<div id="main">     <div id="abc">         <div>             div replaced         </div>     </div>     <div id="xyz" style="display:none">         <div>             div replaced         </div>     </div> </div>

i've given 

$('#main').children('div:eq(0)').css('display','none') $('#main').children('div:eq(0)').replacewith($('#xyz').html())

but, if see output, <div>this div replaced</div> alone , not parent div of i.e <div id="xyz">

i think should want:

$('#main div:first').html($('#xyz').html())
