Python Requests package: Handling xml response

问题:

I like very much the requests package and its comfortable way to handle JSON responses.

Unfortunately, I did not understand if I can also process XML responses. Has anybody experience how to handle XML responses with the requests package? Is it necessary to include another package such as urllib2 for the XML decoding?

回答1:

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

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`

The external lxml project builds on the same API to give you more features and power still.
