When i try to unwrap in string the <p> tag and then wrap the same contents with <div> tag it workes with Chrome, but not with IE.

Example:

<div id="div1">

One string <p>Two string </p>

</div>

$('#div1').find("*").each(function(){

if($(this).prop("tagName").toLowerCase() == 'p')

$(this).contents().unwrap().wrap('<div></div>');

});

Result:

in Chrome

<div id="div1">

One string <div>Two string </div>

</div>

in IE

<div id="div1">

<div>One string </div><div>Two string </div>

</div>

I think this is enough for you to understand the problem, but please contact me if you need more information.

Thank you for your attention.
