在Python中从损坏的xml获取数据

我想从xml中获取数据，但它的结构似乎被破坏了

我有一个示例URL:

https://b2b.snapoutdoor.pl/rest/V1/extendvariantstocart/73478

这是包含产品数据的xml

import requests
import json
from xml.etree import ElementTree
from pprint import pprint

response = requests.get(
    "https://b2b.snapoutdoor.pl/rest/V1/extendvariantstocart/86559",
    headers={"Accept": "application/xml"},
)

node = ElementTree.fromstring(response.content)

data = json.loads(node.text)

这将返回带有四个键的dict：

{'jsonChildsConfig': '{"70259":{"id":"70259","name":"Ski Ultra Merino E - '
                     'black\\/orange","sku":"610306139887","availableQty":6,"regularPrice":69.2367,"finalPrice":69.2367,"promo":false,"discount":0,"bestDiscount":false,"addToCartUrl":"https:\\/\\/b2b.snapoutdoor.pl\\/checkout\\/cart\\/add\\/uenc\\/aHR0cHM6Ly9iMmIuc25hcG91dGRvb3IucGwvcmVzdC9WMS9leHRlbmR2YXJpYW50c3RvY2FydC84NjU1OQ%2C%2C\\/product\\/86559\\/","formKey":"7OWS6VbWucoSg2zg","superAttributes":"36-39 '

                     'Ultra Merino E - '

 'jsonConfig': 'some data',
 'jsonDefaultPlaceholder': 'https://b2b.snapoutdoor.pl/pub/media/catalog/product/placeholder/',
 'jsonSwatchConfig': 'some data'
}

我对

jsonchildscanfig

的值很感兴趣，但是当我试图访问其中的键时，我得到了

TypeError:字符串索引必须是整数

，因为

jsonChildsConfig

的值是字符串

我想从

sku

和

availableQty

中获取所有sku和库存值，但它们的类型是字符串，无法获取

data['jsonChildsConfig']['70259']['sku']

或

数据['jsonChildsConfig']['70259']['availableQty']

我还尝试通过t

json.loads（）

将此字符串转换为json，但没有成功

---

你能帮我吗 使用json.loads将数据['jsonChildsConfig']的值转换为dict应该可以工作

>>> childConfigDetails = json.loads(data['jsonChildsConfig'])
>>> childConfigDetails['70259']['sku']
'610306139887'

---

使用json.loads将数据['jsonChildsConfig']的值转换为dict应该可以工作

>>> childConfigDetails = json.loads(data['jsonChildsConfig'])
>>> childConfigDetails['70259']['sku']
'610306139887'

要修复字典，需要对所有值应用

json.loads

​​不包括非json格式的

'jsonDefaultPlaceholder'

：

del data['jsonDefaultPlaceholder']
new_data = {k: json.loads(v) for k, v in data.items() if v}
new_data['jsonChildsConfig']['70259']['sku']

#output: '610306139887'

或者，如果要将感兴趣的键转换为整数值：

del data['jsonDefaultPlaceholder']
new_data2 = {k: {(int(key) if key.isdigit() else key): val for key,val in json.loads(v).items()} for k, v in data.items() if v}
new_data2['jsonChildsConfig'][70259]['sku']

# output: '610306139887'

# output: '610306139887'

json.loads（d['jsonChildsConfig']）

在上述示例中对我有效。

json.loads（d['jsonChildsConfig']）

在上述示例中对我有效。
