YAML vs XML
YAML vs XML compared — readability, structure, comments and use cases, with free formatters for both.
YAML and XML both describe structured data, but YAML favours clean, indentation-based readability for config files, while XML offers attributes, namespaces and schema validation for documents and interchange.

Is YAML easier to read than XML?
For most config, yes — YAML drops closing tags and uses indentation, so files are shorter and cleaner. XML is more explicit and self-describing, which helps for documents and validation.
