解析与BS4此示例文件,从蟒蛇2.7.6:BeautifulSoup(BS4)解析错误
<html>
<body>
<p>HTML allows omitting P end-tags.
<p>Like that and this.
<p>And this, too.
<p>What happened?</p>
<p>And can we <p>nest a paragraph, too?</p></p>
</body>
</html>
使用:
from bs4 import BeautifulSoup as BS
...
tree = BS(fh)
HTML有,望穿秋水,允许省略结束标签各种元素类型,包括P(检查模式或解析器)。然而,BS4的美化()这份文件表明,它并没有结束任何这些段落,直到它看到</BODY>:
<html>
<body>
<p>
HTML allows omitting P end-tags.
<p>
Like that and this.
<p>
And this, too.
<p>
What happened?
</p>
<p>
And can we
<p>
nest a paragraph, too?
</p>
</p>
</p>
</p>
</p>
</body>
这不是美化()的错,因为手动遍历树我得到同样的结构:
<[document]>
<html>
␊
<body>
␊
<p>
HTML allows omitting P end-tags.␊␊
<p>
Like that and this.␊␊
<p>
And this, too.␊␊
<p>
What happened?
</p>
␊
<p>
And can we
<p>
nest a paragraph, too?
</p>
</p>
␊
</p>
</p>
</p>
</body>
␊
</html>
␊
</[document]>
现在,这将是XML正确的结果(至少到</BODY>,此时它应该报告WF错误)。但这不是XML。是什么赋予了?
