在python中解析xml

Question

我想解析xml文件中的文本.考虑到我在file.xml中有一些行

<s id="1792387-2">Castro Verde is situated in the Baixo Alentejo Subregion within a territory known locally as the Campo Branco (English: White Plains).</s>

如何从上面的行中提取以下文本:

Castro Verde is situated in the Baixo Alentejo Subregion within a territory known locally as the Campo Branco (English: White Plains).

在对文本进行一些更改后,我希望返回带有相同标记的更改文本,如下所示.

<s id="1792387-2"> Changed Text </s>

请任何建议.谢谢!

Answer 1

LXML使这一点变得特别容易.

>>> from lxml import etree
>>> text = '''<s id="1792387-2">Castro Verde is situated in the Baixo Alentejo Subregion within a territory known locally as the Campo Branco (English: White Plains).</s>'''
>>> def edit(s):
...     return 'Changed Text'
... 
>>> t = etree.fromstring(text)
>>> t.text = edit(t.text)
>>> etree.tostring(t)
'<s id="1792387-2">Changed Text</s>'
