在 JSON 和 XML 格式之间双向转换，正确处理结构
JSON is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is widely used in web APIs, configuration files, and data storage.
XML is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. It is commonly used in web services (SOAP), configuration files, and document formats.
JSON arrays with multiple elements of the same type are wrapped using repeated XML tags. JSON object keys containing special characters are sanitized for valid XML element names. Null values produce self-closing XML tags.
Converting between JSON and XML is useful when integrating modern REST APIs with legacy SOAP services, migrating data formats, working with different configuration systems, or transforming data for reporting tools.

<name>John</name>

</root>{"items": [1, 2, 3]}<root>
<items>1</items>
<items>2</items>
