XML Parsing, Formatting, and JSON Conversion Notes

XML is still common in payment callbacks, legacy APIs, RSS feeds, sitemaps, and enterprise integrations. FormaX formats XML, checks basic structure, and converts between XML and JSON for modern frontend or Node.js workflows.

During conversion, pay attention to attributes, namespaces, and repeated nodes. JSON has no single canonical representation for them, so confirm the target system contract before storage or API calls.

Recommended Workflow

  1. Format XML first and inspect the root element, repeated nodes, and attributes.
  2. After converting XML to JSON, check whether attributes are stored under _attributes.
  3. If namespaces are present, keep the original XML for audit and troubleshooting.
  4. Before converting JSON back to XML, confirm the required root element and node order.

Common XML Fragment

<order id="A100"><total currency="USD">49.00</total><status>paid</status></order>

Limits and Recommendations

  • XML attributes, CDATA, and namespaces may need manual review after conversion.
  • The tool does not fetch external DTDs or execute external entities, making it suitable for structure checks.
  • When integrating with third parties, keep the original XML, converted JSON, and API response together.

FAQ

Why does XML to JSON create _attributes?

XML attributes are not normal child elements. _attributes preserves them without colliding with same-name elements.

Will JSON back to XML be byte-for-byte identical?

Simple structures preserve meaning, but namespaces, whitespace, node order, and CDATA may require manual review.
