如何解决xml 到 json 的转换 - 如何将子节点和子元素从 xml 转换为 json
我们正在尝试将 xml 转换为 json。 子元素“EmployeeCode”无法识别。错误：在第 15 行执行 XSLT 时出错：xml-to-json：必须具有 key 属性的子元素。需要考虑xml到json转换的子元素和子元素。
xml文件：
<root>
<Name>Alex</Name>
<Age>42</Age>
<item>
<number>314</number>
<name>foo</name>
<EmployeeCode>
<id>F21</id>
<Department>
<Designation>Engineer</Designation>
</Department>
<Status>Contractor</Status>
</EmployeeCode>
</item>
<item>
<number>42</number>
<name>bar</name>
<EmployeeCode>
<id>F24</id>
<Department>
<Designation>Manager</Designation>
</Department>
<Status>Full-time</Status>
</EmployeeCode>
</item>
<data>test</data>
</root>
xsl 代码：

预期的 Json 文件：
{
"Name": "Alex","Age": 42,"item": [
{
"number": 314,"name": "foo","EmployeeCode": {
"id": "F21","Department": {
"Designation": "Engineer"
},"Status": "Contractor"
}
},{
"number": 42,"name": "bar","EmployeeCode": {
"id": "F24","Department": {
"Designation": "Manager"
},"Status": "Full-time"
}
}
],"data": "test"
}
解决方法
这是对之前代码的改进尝试：
-----> Building on the Heroku-20 stack
-----> Using buildpack: heroku/python
-----> Python app detected
-----> No Python version was specified. Using the buildpack default: python-3.9.5
To use a different version,see: https://devcenter.heroku.com/articles/python-runtimes
-----> Installing python-3.9.5
-----> Installing pip 20.2.4,setuptools 47.1.1 and wheel 0.36.2
-----> Installing SQLite3
-----> Installing requirements with pip

You may need to update application code to resolve this error.
Or,you can disable collectstatic for this application:
