以下是我处理的HTML代码
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>sdasdsadsad</title>
<link rel="alternate" media="only screen and (max-width: 640px)" href="local:80" />
<meta name="description" content="sdddsdsdsdsdsd">
<meta name="keywords" content="3333333333333333">
<meta property="og:title" content="444444444444444444444444">
<meta property="og:type" content="article">
<meta property="og:description" content="dsdsdsdsddsds">
</head>
<body></body>
</html>
我希望该行包含标记＆＃34; <meta name = description＆＃34; ，它没有关闭元素</meta>。有我的代码
import glob, os, re, urllib2, codecs
from bs4 import BeautifulSoup
from bs4 import SoupStrainer
html_doc = """
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>sdasdsadsad</title>
<link rel="alternate" media="only screen and (max-width: 640px)" href="local:80" />
<meta name="description" content="sdddsdsdsdsdsd">
<meta name="keywords" content="3333333333333333">
<meta property="og:title" content="444444444444444444444444">
<meta property="og:type" content="article">
<meta property="og:description" content="dsdsdsdsddsds">
</head>
<body></body>
</html>
"""
soup = BeautifulSoup(html_doc)
aa = soup.find("meta", {"name":"description"})
print aa.encode("utf-8")
运行Python代码，但控制台显示
<meta content="sdddsdsdsdsdsd" name="description">
<meta content="3333333333333333" name="keywords">
<meta content="444444444444444444444444" property="og:title">
<meta content="article" property="og:type">
<meta content="dsdsdsdsddsds" property="og:description">
</meta></meta></meta></meta></meta>
但是如果＆＃34; <meta content="sdddsdsdsdsdsd" name="description">＆＃34;有一个紧密的元素</meta>，我可以得到完全一行：
<meta content="sdddsdsdsdsdsd" name="description"> </meta>
您是否想告诉我为什么BeautifulSoup获取<meta name = description下的所有HTML标记，以及如何获取该行包含<meta name = description
感谢。
