Check XML syntax, validate against XSD 1.0 (including multi-file schema projects) and format XML locally in your browser, no account needed. Every error guide comes with a broken and a corrected example you can open and test. Optional server checks add XSD 1.1, Schematron and e-invoice rules (EN 16931, XRechnung, Factur-X, KSeF, RO e-Factura, Croatia), only after explicit consent. Free for single files; Pro and Team add batches, saved schemas, an API and a GitHub Action.

Could you build this?
Partial Browser-side XML formatting, XSD 1.0 validation, and the tested error-fix examples are buildable with WebAssembly libraries like libxml2. The server-side XSD 1.1, Schematron, and EN 16931 e-invoice rule checks need specialist standards knowledge and correct validation engines.
What it would actually take: Build the UI and XML/XSD 1.0 validation client-side with a WASM build of libxml2 or a similar validator, plus a curated library of broken/fixed examples. The server tier would run Saxon (XSLT/XSD 1.1), a Schematron engine, and maintained EN 16931/Peppol rule sets, which requires someone who understands those specifications and keeps them current.
