如何使用Beautiful Soup(库)在HTML页面中的标题标记之后添加元标记.我使用python语言进行编码,但无法执行此操作.
使用soup.create_tag()创建一个新的<meta>标签,设置该属性并将其添加到您的文档<head>.
metatag = soup.new_tag('meta')
metatag.attrs['http-equiv'] = 'Content-Type'
metatag.attrs['content'] = 'text/html'
soup.head.append(metatag)
演示:
>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup('''\
... <html><head><title>Hello World!</title>
... </head><body>Foo bar</body></html>
... ''')
>>> metatag = soup.new_tag('meta')
>>> metatag.attrs['http-equiv'] = 'Content-Type'
>>> metatag.attrs['content'] = 'text/html'
>>> soup.head.append(metatag)
>>> print soup.prettify()
<html>
<head>
<title>
Hello World!
</title>
<meta content="text/html" http-equiv="Content-Type"/>
</head>
<body>
Foo bar
</body>
</html>
