如果想保存一篇指定的博文（只要正文），该怎么做呢？
其实只要我们预先保存下博文的js、css和一些控制正文的html标记，然后把正文内容填充进去就可以了。
以下lua脚本可以获得
<div id="article_content" class="article_content"> 正文 </div>
start.html
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="http://static.blog.csdn.net/scripts/jquery.js" type="text/javascript"></script>
<link rel="Stylesheet" type="text/css" href="http://static.blog.csdn.net/skin/skin-blue/css/style.css?v=1.1" />
<link rel="shortcut icon" href="http://c.csdnimg.cn/public/favicon.ico" />
<link type="text/css" rel="stylesheet" href="http://static.blog.csdn.net/scripts/SyntaxHighlighter/styles/default.css" />
</head>
<body>
<div id="container">
