Is my XML data sent to a server?

No. The entire conversion runs in your browser using the native DOMParser and js-yaml library. Your data never leaves your device.

Does it support XML attributes?

Yes. Attributes on an element are grouped under an `@attributes` key in the YAML output, following a common convention for XML-to-object mapping.

What happens with repeated sibling elements?

Repeated elements with the same tag name at the same level are converted into a YAML sequence (list), which is the natural YAML equivalent.

Does it handle XML namespaces?

Namespace prefixes are preserved as-is in the key names (e.g., `ns:element`). Namespace declarations (`xmlns:*`) are treated like regular attributes.

Can I convert very large XML files?

The tool works well for typical config files and API payloads. Very large files (several MB) may be slow depending on your device, since all processing is done in the browser.
