如何用LXML解析破碎的HTML
如何用LXML解析破碎的HTML
提问于 2013-10-01 22:01:08
我正在尝试使用Python2.5和2.7上的LXML解析器来解析损坏的HTML
与LXML文档(http://lxml.de/parsing.html#parsing-html)不同的是，解析损坏的超文本标记语言不起作用：
from lxml import etree
import StringIO
broken_html = "<html><head><title>test<body><h1>page title</h3>"
parser = etree.HTMLParser()
tree = etree.parse(StringIO.StringIO(broken_html))结果：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

不要只是构造解析器，要使用它(根据您链接的示例)：
>>> tree = etree.parse(StringIO.StringIO(broken_html), parser=parser)
>>> tree
<lxml.etree._ElementTree object at 0x2fd8e60>或者使用lxml.html作为快捷方式：
>>> from lxml import html
>>> broken_html = "<html><head><title>test<body><h1>page title</h3>"
>>> html.fromstring(broken_html)
<Element html at 0x2dde650>Stack Overflow用户

您可以尝试使用lxml.html
>>> import lxml.html
>>> broken_html = "<html><head><title>test<body><h1>page title</h3>"
>>> root = lxml.html.fromstring(broken_html)
>>> lxml.html.tostring(root)
'<html><head><title>test</title></head><body><h1>page title</h1></body></html>'页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
