如何从具有HTML页面的responseText获取特定的div内容

我在responseText中得到整个html页面，我只想解析/ 过滤responseText到 获取特定的div说测试和基础内容.我不会 想要修改服务器端代码以仅发送所需的div responseText.

I am getting the whole html page in responseText, i just want to parse/ filter the responseText to get a specific div say test and underlying contents. I would not like to modify the server side code to send just required div in responseText.

url: "Someurl",
datatype: "text/html",
success : function(responseText) 
{
    alert(responseText);
dat = $(data).filter("#test").html();
alert(dat);//getting null
$('#test').html(dat);
