我想把字符串s转化为jquery对象，然后对其进行选择，但是如下代码并没有得到我想要的结果，请各位帮我看看，不胜感激！
var s = "<p>one</p> <div><p>two</p></div> <p>three</p>"
var tt=$(s).find("div > p");
alert(tt.html());
var s = "<p>one</p> <div><p>two</p></div> <p>three</p>"
var tt=$(s).find("div > p");
alert(tt.html());
var tt=$("<html>"+s+"</html>").find("div > p");
alert(tt.html());
<html><head>
<script type="text/javascript" charset="gb2312" src='jquery-1.3.2.min.js'></script>
<meta http-equiv="content-type" content="text/html; charset=gb2312"/>
<script type="text/javascript">
$(document).ready(function()
{
var s = " <p>one </p> <div> <p>two </p> </div> <p>three </p>"
var tt=$("<html>"+s+"</html>").find("div > p");
alert(tt.html());
});
</script>
<title></title></head><body>
</body></html>
{
var s = " <p>one </p> <div> <p>two </p> </div> <p>three </p>"
var tt=$(" <div>"+s+" </div>").find("div > p");
alert(tt.html());
}); 原来<html>他不认...

var s = "<html><body><p>one </p> <div> <p>two </p> <p>three</p></div> <p>three </p></body></html>"
var tt=$(" <div>"+s+" </div>").find("p");
alert(tt.html());
它返回的只是第一个“one”，而不返回其它的，请问这又是什么原因？而且为什么非要加个"<div>"呢？
