java正则表达式问题

Question

String pstr = "(<br /><div class=\"tpc_content\">|<iframe\\s(.+?)</iframe>|onclick(.+?)style='cursor:pointer'><br>|";
       pstr = pstr + "<span style='font-size:1px'> </span>|<a target=\"_blank\" onmouseover(.+?)torrent.gif' align='absmiddle'>)";
       p = Pattern.compile(pstr,Pattern.CASE_INSENSITIVE); //启用大小写
m = p.matcher(url);
while(m.find()) {
url = url.replace(m.group(), "");
}
System.out.println(url);

为什么对<IFRAME </IFRAME>匹配不到呢

Answer 1

String   pstr ="<iframe\\s*(.*?)></iframe>";
这个足以

Answer 2
