将URL中的XML解析为python对象 [英] Parse XML from URL into python object

问题描述

goodreads网站具有此API，用于访问用户的货架： https://www.goodreads.com/review/list/20990068.xml?key=nGvCqaQ6tn9w4HNpW8kquw&v=2&shelf=toread

The goodreads website has this API for accessing a user's 'shelves:' https://www.goodreads.com/review/list/20990068.xml?key=nGvCqaQ6tn9w4HNpW8kquw&v=2&shelf=toread

它返回XML。我正在尝试创建一个Django项目，该项目通过此API在书架上显示书籍。我正在寻找一种方法（或者是否有比该方法更好的方法）来编写我的视图，以便可以将一个对象传递给模板。当前，这是我正在做的事情：

It returns XML. I'm trying to create a django project that shows books on a shelf from this API. I'm looking to find out how (or if there is a better way than) to write my view so I can pass an object to my template. Currently, this is what I'm doing:

import urllib2

def homepage(request):
    file = urllib2.urlopen('https://www.goodreads.com/review/list/20990068.xml?key=nGvCqaQ6tn9w4HNpW8kquw&v=2&shelf=toread')
    data = file.read()
    file.close()
    dom = parseString(data)

如果我正确地执行此操作，我不完全确定如何操作该对象。我正在关注教程。

I'm not entirely sure how to manipulate this object if I'm doing this correctly. I'm following this tutorial.

推荐答案

我将使用 xmltodict 从 XML 数据结构中制作一个python字典，并将该字典传递到上下文中的模板：

I'd use xmltodict to make a python dictionary out of the XML data structure and pass this dictionary to the template inside the context:

import urllib2
import xmltodict

def homepage(request):
    file = urllib2.urlopen('https://www.goodreads.com/review/list/20990068.xml?key=nGvCqaQ6tn9w4HNpW8kquw&v=2&shelf=toread')
    data = file.read()
    file.close()

    data = xmltodict.parse(data)
    return render_to_response('my_template.html', {'data': data})
