I tried that with the https://validator.w3.org/, also using .xhtml as extension as it seems that it is what makes the w3c validator consider that it is XML, with and without <?xml?>, and I get: Schema Error: XML document with no namespace; cannot determine any schema to use for validation. ... Also, what could I use for offline validation? The w3c-markup-validator package does not seem to handle HTML5, and the vnu https://validator.github.io/validator/ validator does not seem to be packages in debian.
I don't know if people even use old-style XML/HTML validators these days, or if there are good free validators that match modern html. Anything that uses a DTD would seem to have limited usefulness. The W3C Markup Validator (https://github.com/w3c/markup-validator/) suggests the NU Validator (https://github.com/validator/validator/) for HTML5. Maybe try the online version first: https://validator.w3.org/nu/ If it seems helpful you can download and build a local version. -- --Per Bothner per@bothner.com http://per.bothner.com/
