我正在尝试保存这个 json 对象：

到 XML 文件或 Python 代码中的 RDF。我没有找到关于 rdf 的帖子，所以我尝试了 XML。我还尝试将列表更改为 dict ，就像在这篇文章中一样：

Python Json loads() returning string instead of dictionary?

但它不起作用。在 views.py 我有：

 fileroot = '[{"patient_id":"'+record_id+'"},'+content0+','+content1+','+content2+']'
jsonData = simplejson.loads(fileroot)

它返回 'list' 对象没有属性 'items'。如果我将其更改为：

  fileroot = '[{"patient_id":"'+record_id+'"},'+content0+','+content1+','+content2+']'
jsonData = simplejson.loads(fileroot)[0]

它什么也不返回。我也尝试过这个链接：

但它不再工作了。

【问题讨论】：

你有什么问题？您的 json 文件在我的控制台中运行。
我无法将其转换为 XML 或 RDF 并保存

标签： python xml json rdf

【解决方案1】：

这会将您的 json 对象转换为 xml

import simplejson
content = simplejson.loads(YourJsonObject)


from xml.etree.ElementTree import Element
from xml.etree.ElementTree import tostring

def dict_to_xml(tag, d):
    '''
    Turn a simple dict of key/value pairs into XML
    '''
    elem = Element(tag)
    for key, val in d.items():
        child = Element(key)
        child.text = str(val)
        elem.append(child)
    return elem

for i in range(1,len(content)):
    e = dict_to_xml('SomeNode',content[i][0])

    # print e
    print tostring(e)
