innerHTML problem with internet explorer (supposed)

I lost some time to debug this

$("#link").click(function(){
   $("#target").load('url/to/load');
});

The problem is on Internet Explorer (all version) that refuse to load data in #target, using $.get and innerHTML(data) do not help. The problem is with no well formed html! Internet Explorer refuse to load in dom a malformed html.
Thus

$("#link").click(function(){
   $("#target").load('url/to/load');
   window.open('url/to/load');
});

will load interested html in new popup (letit open!) and wrapping with <xml></xml> document should be well formed: open with conglomerate or checking with other tool make life easy.
