Using the Validator

To use the validator, download a version of it. For fastest startup, download the complete package. If you already have the SGML libraries from W3C, then you can download the version without DTDs. I have additionally included a download for the original HTML documents that were included with the CGI version, but these are not used for the command line version (although include important information, such as licensing).

If you download the full version, simply extract the tar file to a directory (it will create a "w3cvalidator" subdirectory). Inside there you will find a "bin" directory containing the "check" program. Run this in accordance with the usage notes (see attached file)

If you already have the SGML libraries, then you can save a bit of downloading time and use the no-dtd version. Follow the same procedure as above, but copy the sgml-lib directory from the tar file from the W3C into the etc directory.
