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>[email protected]</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。
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）：
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>[email protected]</mail>
</element>
</root>
