获取HTML源码文档中<div class="stat stat_area"></div>格式中的内容
我要获取的是该http://v.youku.com/v_show/id_XMzI5NTIyNzMy.html页面源码中的<div class="stat stat_area">内容</div>，这个DIV中的内容，可是提取为空，正则表达式应该也没错，高手进来帮个帮。

public StringBuffer getContent(URL url)

try {
InputStreamReader istreamReader = new InputStreamReader(url.openStream());
int ch = 0;
//ch读取的字符，如果已到达流的末尾，则返回 -1
while ((ch = istreamReader.read()) != -1)
contentBuffer.append((char)ch);
  } catch (IOException e) {

  }

  return contentBuffer;

}

for(int i=0;i<list.size();i++)
temp += list.get(i);
return temp;
}
