Python请求包:处理xml响应


114

我非常喜欢该requests程序包及其舒适的方式来处理JSON响应。

不幸的是,我不知道是否还可以处理XML响应。有没有人体验过如何使用该requests包处理XML响应?是否需要包括另一个用于XML解码的包?

requests不处理解析XML响应,否。XML响应本质上比JSON响应复杂得多,如何将XML数据序列化为Python结构几乎不那么简单。

Python带有内置的XML解析器。我建议您使用ElementTree API

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

或者,如果响应特别大,请使用增量方法:

response = requests.get(url, stream=True)
# if the server sent a Gzip or Deflate compressed response, decompress
# as we read the raw stream:
response.raw.decode_content = True

events = ElementTree.iterparse(response.raw)
for event, elem in events:
    # do something with `elem`

外部lxml项目建立在相同的API上,仍然为您提供更多功能和强大功能。
