How to convert < into < in lxml, Python?

问题

There's a xml file:

<body>
    <entry>
         I go to <hw>to</hw> to school.
    </entry>
</body>

For some reason, I changed <hw> to <hw> and </hw> to </hw> before parsing it with lxml parser.

<body>
    <entry>
         I go to &lt;hw&gt;to&lt;/hw&gt; to school.
    </entry>
</body>

But after modifying the parsed xml data, I want to get a <hw> element, not <hw>. How can I do that?

回答1:

First find a unescape function:

from xml.sax.saxutils import unescape

entry=body[0]

unescape and replace it with the original:

body.replace(entry, e.fromstring(unescape(e.tounicode(entry))))

回答2:

If you know which element contains wrongly escaped elements:

# parse whole document as usual..
# find the entry element..
# parse the fragment
fragment = lxml.fromstring(entry.text)
# (optionally) add the fragment to the tree
entry.text = None
entry.append(fragment)
