Frequently Asked Questions

What is the difference between XML and JSON?

XML uses tag-based structure, suitable for documents and configs. JSON uses key-value pairs, is more lightweight, and is the standard format for modern Web APIs.

Does conversion support XML attributes?

Yes. XML element attributes are preserved as special keys (e.g. {'@'}attributes) in the JSON result.

How are XML namespaces handled when converting to JSON?

XML namespace prefixes (like <ns:tag>) are typically preserved as part of the key name in JSON (e.g. ns:tag). The namespace URI declaration attributes (xmlns:ns=...) are handled as regular attributes. For complex namespace-heavy XML, review the output carefully as the mapping can vary between conversion implementations.

How do I handle the mapping between XML attributes and elements when converting to JSON?

XML has both attributes and elements as data carriers, while JSON only has key-value pairs. Common conversion strategies: map attributes to special JSON keys (e.g., {'@'}attr or a nested _attributes object); map text content to a #text key; handle arrays carefully (single vs. multiple child elements should both be converted to arrays for consistency). Different libraries (xml2js, fast-xml-parser) use different strategies — choose conversion options based on your use case.
