在网上找的用正则表达式过滤网页标签，一行行的读取，只能删除掉一行，像是跨行的<script>无法删除，求解答
<script>document.documentElement.className = document.documentElement.className.replace( /(^|\s)client-nojs(\s|$)/, "$1client-js$2" );</script>
上面的就能用正则表达式处理掉

下面跨行的用正则表达式就处理不了了，求解答，怎么把下面的这些跨行的东西放到一起，交给正则表达式处理
<script>(window.RLQ = window.RLQ || []).push(function () {
