解析 HTML：Python 中的 lxml 错误

Question

我正在编写一个简单的脚本来从此处获取大灰色表格。

我的代码如下：

import urllib2
from lxml import etree

html = urllib2.urlopen("http://www.afi.com/100years/movies10.aspx").read()

root = etree.XML(html)

但我在最后一条语句中收到错误。

Traceback (most recent call last):
  File "D:\Workspace\afi100\afi100.py", line 13, in <module>
    root = etree.XML(html)
  File "lxml.etree.pyx", line 2720, in lxml.etree.XML (src/lxml/lxml.etree.c:52577)
  File "parser.pxi", line 1556, in lxml.etree._parseMemoryDocument (src/lxml/lxml.etree.c:79602)

  File "parser.pxi", line 568, in lxml.etree._raiseParseError (src/lxml/lxml.etree.c:71683)
XMLSyntaxError: Space required after the Public Identifier, line 3, column 59

知道如何解决这个错误吗？

谢谢。

Answer 1

如果您尝试使用 XML 解析器解析 HTML，则应该使用 lxml HTML 解析器。

import urllib2
from StringIO import StringIO
from lxml import etree

ufile = urllib2.urlopen("http://www.afi.com/100years/movies10.aspx")

root = etree.parse(ufile, etree.HTMLParser())

print etree.tostring(root)

Answer 2

您链接到的文档不是格式良好的 XHTML，因此您无法使用 XML 解析器来加载它。

您必须使用 HTML 解析器，例如 Beautiful Soup。
