在Python中的XML文件的字符转义 [英] escaping characters in a xml file with python

问题描述

我要逃避一个丑陋的XML文件中的特殊字符（5000行左右长）。这是我要处理XML的例子：

I need to escape special characters in an ugly XML file (5000 lines or so long). Here's an example of XML I have to deal with:

<root>
 <element>
  <name>name & surname</name>
  <mail>[e-mail]</mail>
 </element>
</root>

下面的问题是字符与＆amp;在名字里。你会如何​​特殊字符转义像这样用Python库？我没有找到 BeautifulSoup 。

Here the problem is the character "&" in the name. How would you escape special characters like this with a Python library? I didn't find the way to do it with BeautifulSoup.

推荐答案

如果你不关心在XML你可以使用XML解析器的恢复选项无效字符（看到解析破损的XML与lxml.etree.iterparse ）：

If you don't care about invalid characters in the xml you could use XML parser's recover option (see Parsing broken XML with lxml.etree.iterparse):

from lxml import etree

parser = etree.XMLParser(recover=True) # recover from bad characters.
root = etree.fromstring(broken_xml, parser=parser)
print etree.tostring(root)

输出

<root>
<element>
<name>name  surname</name>
<mail>[e-mail]</mail>
</element>
</root>
