正则，去掉onclick
$str = '
';
我想去掉上面字符串中的onclick，我写的正则如下：
function clear_onclick($document) {
if (!$document) return $document;
$search = array(
"/onclick=('|\"|)?(.*)('|\"|)/ismUe",
);
$replace = array( "",
);
$text = preg_replace($search,$replace,$document);
return $text;
}
echo clear_onclick($str);
貌似达不到我的效果，请教一下如何写正则去掉？
------解决方案--------------------
"/onclick=('|\")?(.*)\\1/sU"
这样就好了吧
