我有一个类似 xml 的文件，该文件在属性中没有引号，attribute="xxx"并且没有标准<?xml version="1.0"?>标题，因此当我尝试使用minidomor解析时elementtree，他们将文件抱怨为not well-formed：

>>> import xml.etree.ElementTree as et
>>> tree = et.parse(infile)
>>> Traceback (most recent call last):
xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 1, column 25

如何读取输入文件？或者我怎样才能使 xml 格式正确？

我的输入文件如下所示：

<contextfile concordance=brown>
<context filename=br-a01 paras=yes>
<p pnum=1>
<s snum=1>
<wf cmd=ignore pos=DT>The</wf>

使用lxml：

mytext="""<contextfile concordance=brown>
<context filename=br-a01 paras=yes>
<p pnum=1>
....
<wf cmd=done pos=VB lemma=say wnsn=1 lexsn=2:32:00::>said</wf>
<wf cmd=done pos=NN lemma=friday wnsn=1 lexsn=1:28:00::>Friday</wf>
<wf cmd=ignore pos=DT>an</wf>
....
....
<punc>``</punc>
<wf cmd=ignore pos=DT>no</wf>
<wf cmd=done pos=NN lemma=evidence wnsn=1 lexsn=1:09:00::>evidence</wf>
<punc>''</punc>
....
<wf cmd=done pos=NN lemma=irregularity wnsn=1 lexsn=1:04:00::>irregularities</wf>
<punc>.</punc>
</s>
</p>
</context>
</contextfile>"""

from lxml import html
parsed = html.fromstring(mytext)
for x in parsed.getiterator(): print x.tag, x.attrib, x.text, x.tail

输出：

contextfile {'concordance': 'brown'} None None
context {'paras': 'yes', 'filename': 'br-a01'} None None
p {'pnum': '1'} 
....

punc {} `` None
