HTML validation on command line

valentine

valentine is a statically linked binary that validates your HTML against the offical W3C HTML spec. Syntax is checked, but only some of the semantic properties. In case of error, valentine gives you the file name, line number, column number, offending text, and issue.

Install it with opam, the OCaml package manager, with

$ opam install valentine

If there is an error then valentine will exit with exit code 1 making it very easy use in your shell scripts.

Example output

$ valentine ex/test.html
File:test.html line 4, column 1: misnested tag: 'body' in 'body'
File:test.html line 4, column 10: unmatched start tag 'em'
File:test.html line 5, column 14: bad token '>' in tag: expected attribute value after '='
File:test.html line 4, column 10: unmatched start tag 'em'
