使用 Python 转义 XML 中未转义的字符 [英] Escape unescaped characters in XML with Python

问题描述

我需要对一个大约 5000 行长的无效 XML 文件中的特殊字符进行转义.这是我必须处理的 XML 示例:

I need to escape special characters in an invalid XML file which is about 5000 lines long. Here's an example of the XML that I have to deal with:

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

这里的问题是字符&"在名字里.您将如何使用 Python 库转义这样的特殊字符?我没有找到使用 BeautifulSoup 的方法.

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 a way to do it with BeautifulSoup.

推荐答案

如果您不关心 xml 中的无效字符，您可以使用 XML 解析器的 recover 选项(请参阅 使用 lxml.etree.iterparse 解析损坏的 XML):

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>
