[英]Convert XML to JSON with python, attributes of the father after the child nodes in the JSON
我需要使用 python 將一個文件 XML 轉換為 JSON,但我需要將父親的屬性放在 Z7702F11C1D7A2B8 中的子節點之后
我現在的代碼是這樣的。
def generate_json(self, event=None):
# opening the xml file
with open(self.fn ,"r") as xmlfileObj:
data_dict = lib.xmltodict.parse(xmlfileObj.read(),attr_prefix='_')
xmlfileObj.close()
jsonObj= json.dumps(data_dict, sort_keys=False)
restored = json.loads(jsonObj)
#storing json data to json file
with open("data.json", "w") as jsonfileObj:
jsonfileObj.write(jsonObj)
jsonfileObj.close()
我需要這個;
{
"datasetVersion": {
"metadataBlocks": {
"citation": {
"fields": [
{
"value": "Darwin's Finches",
"typeClass": "primitive",
"multiple": false,
"typeName": "title"
}
],
"displayName": "Citation Metadata"
}
}
}
}
代替:
{
"datasetVersion": {
"metadataBlocks": {
"citation": {
"displayName": "Citation Metadata",
"fields": [
{
"value": "Darwin's Finches",
"typeClass": "primitive",
"multiple": false,
"typeName": "title"
}
]
}
}
}
}
不按字母順序更改 sort_keys=False ,我只需要將節點父親的屬性更改為最終。
在某些網站上按我的需要制作: https://www.convertjson.com/xml-to-json.htm
還有一個不怎么樣:

有人可以幫助我嗎?
我可以使用https://pypi.org/project/xmljson/庫格式化,我修改了 BadgerFish 樣式
class BadgerFish(XMLData): # 約定從項目中更改為前綴 _ 並排序父節點的屬性 '''在 XML 和使用 BadgerFish 約定的數據之間轉換''' def init (self, **kwargs): super (獾魚,自我)。 初始化(attr_prefix='_', text_content='$', **kwargs)
我將屬性的前綴更改為“_”
by 否則只改了**# modify 把父屬性改完,怎么看代碼
def data(self, root):
'''Convert etree.Element into a dictionary'''
value = self.dict()
children = [node for node in root if isinstance(node.tag, basestring)]
if root.text and self.text_content is not None:
text = root.text
if text.strip():
if self.simple_text and len(children) == len(root.attrib) == 0:
value = self._fromstring(text)
else:
value[self.text_content] = self._fromstring(text)
count = Counter(child.tag for child in children)
for child in children:
# if child.tag == "System_State_Entry": print(child.tag)
if count[child.tag] == 1:
value.update(self.data(child))
else:
result = value.setdefault(child.tag, self.list())
result += self.data(child).values()
# if simple_text, elements with no children nor attrs become '', not {}
if isinstance(value, dict) and not value and self.simple_text:
value = ''
**# modify to put the father atributes to finish
for attr, attrval in root.attrib.items():
attr = attr if self.attr_prefix is None else self.attr_prefix + attr
value[attr] = self._fromstring(attrval)**
return self.dict([(root.tag, value)])
