BeautifulSoup 返回网页标签的名称、父标签名称、行号、完整路径
应用beatifulsoup完成网页标签的名称、父标签名称、行号、完整路径的获取，这里reversed实现对网页标签的遍历。
示例html文件：
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type"/>
<meta content="IE=Edge" http-equiv="X-UA-Compatible"/>
<meta content="webkit" name="renderer"/>
<title>交易网</title>
</head>
<body>
<div id="menutab_8_2" style="">
<link href="../Template/Default/ztbzx/css/style.css" rel="stylesheet" type="text/css"/>
<script src="../template/default/js/jquery-1.11.0.min.js" type="text/javascript"></script>
<script>
function iFrameHeight() {
var total = document.getElementById("ZtbggxxDetail_LblCount").innerHTML;
for(var i=0;i<parseInt(total);i++)
{
var ifm = document.getElementById("iframejjgz"+i.toString());
var subWeb = document.frames ? document.frames["iframejjgz"+i.toString()].document : ifm.contentDocument;
if (ifm != null && subWeb != null) {
ifm.height = subWeb.body.scrollHeight;
}
}}
</script>
