JSON to XML

Crate

Documentation

Parameters

• json_string: The input JSON string to be converted into XML. It can contain objects, arrays, and strings.
• root: The name of the root. It will become the root element of the XML if the JSON contains top-level @ attributes.

Returns

A string containing the XML representation of the input JSON, including necessary XML attributes.

Notes

• This function works recursively to handle nested structures and arrays.
• Attributes are prefixed with @ in the JSON input and are converted to XML attributes.
• The order of attributes in the XML elements may differ.
• root is only used with json_to_xml_with_root, since json_to_xml uses "Root" by default.
• The root start and end tags will be included only if the top-level JSON object contains @ attributes.
• Empty objects are converted into self-closing <Tag/>
• Empty arrays [] are converted into <TagItem>...</TagItem>
• null values are converted into <None/>

Example

use json_to_xml::generate_xml::json_to_xml_with_root;

let json_string = r#"
{
    "@xmlns:addr": "http://standards.fi/schemas/personData/addresses",
    "@xmlns:pr": "http://standards.fi/schemas/personData/person",
    "person": {
        "name": "John Doe",
        "age": "30",
        "@id": "1234",
        "addresses": [
            {
                "street": "123 Main St",
                "city": "Springfield",
                "@type": "primary"
            },
            {
                "street": "456 Oak Ave",
                "city": "Shelbyville",
                "@type": "secondary"
            }
        ]
    }
