Use `<doc xmlns:x="urn:example"><p>Hello <x:strong>world</x:strong>!</p><empty /></doc>` and choose Format XML with two spaces.
Expected formatted output
Doc opens on the first line. The complete source `<p>Hello <x:strong>world</x:strong>!</p>` appears on the second line after two spaces, unchanged inside because the direct words, spaces, punctuation, and child element form mixed content. `<empty />` appears on the third line with two spaces, preserving its original space before the slash. Doc closes on the fourth line. The `x` prefix and `urn:example` declaration are not renamed or reordered.
Expected evidence
The parsed tree reports four elements, one attribute, maximum depth three, and one namespace declaration. The formatter does not claim that `urn:example` resolves to a reachable resource: namespace names are identifiers, not a network instruction in this workflow. No request is made, and the document is rendered only as text in the result surface.
Reproduce it in the tool
Open the formatter, paste the complete input exactly as printed, keep two-space indentation, and choose Format XML. Compare every line with the expected output before copying or downloading it. Then choose Check only to see that the evidence comes from the parsed document rather than from the formatting view. The example contains no private endpoint or operational identifier and makes no request to example.com or any other host.
