Frequently Asked Questions
What is XML formatting?
Adding proper indentation and line breaks to make hierarchical XML structure readable.
How to validate XML?
This tool checks well-formedness: proper tags, correct nesting, and valid characters.
XML vs JSON?
JSON is simpler for web APIs. XML supports attributes, namespaces, and schemas for enterprise systems.
What is the difference between well-formed and valid XML?
Well-formed XML follows basic syntax rules (matching tags, proper nesting). Valid XML additionally conforms to a schema (DTD or XSD) that defines allowed elements and structure.
How do I convert XML to JSON programmatically?
Use libraries like xml2js (Node.js), xmltodict (Python), or Jackson (Java). Note that XML attributes and mixed content have no direct JSON equivalent, so conversion may lose some structural information.
About XML
XML (eXtensible Markup Language) is a markup language for encoding documents in a human-readable and machine-readable format.
It's widely used for data exchange, configuration files, web services (SOAP), RSS feeds, and document formats like SVG and XHTML.
