Python 使用getElementsByTagName进行健壮的DOM解析

以下内容（摘自“深入Python”）

失败于

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/path/to/htmlToNumEmbedded.py", line 2, in <module>
    xmldoc = minidom.parse('/path/to/index.html')
  File "/usr/lib/python2.7/xml/dom/minidom.py", line 1918, in parse
    return expatbuilder.parse(file)
  File "/usr/lib/python2.7/xml/dom/expatbuilder.py", line 924, in parse
    result = builder.parseFile(fp)
  File "/usr/lib/python2.7/xml/dom/expatbuilder.py", line 207, in parseFile
    parser.Parse(buffer, 0)
xml.parsers.expat.ExpatError: mismatched tag: line 12, column 4

但似乎有些笨拙：有没有我忽略的内置函数

或者使用getElementsByTagName进行健壮DOM解析的另一种更优雅的方法？

您可以使用BeautifulSoup进行以下操作：

from bs4 import BeautifulSoup

with open('/path/to/index.html') as f:
    soup = BeautifulSoup(f)
soup.find_all("img")

如果需要元素列表，请参见，而不是迭代

元素的返回值。iter

，请在其上调用

list

：

from lxml import html
reflist = list(html.parse('/path/to/index.html.html').iter('img'))

from bs4 import BeautifulSoup

with open('/path/to/index.html') as f:
    soup = BeautifulSoup(f)
soup.find_all("img")

from lxml import html
reflist = list(html.parse('/path/to/index.html.html').iter('img'))
