in reply to HTML::HTML5::Parser weirdness

As per Corion's post, make sure you're able to read the file okay file exists, has correct permissions, etc. Try reading the file using normal Perl open, readline, etc, then sending the string to parse_string on the parser object, rather than using parse_file.

If that still doesn't work, try emailing the file to the author of that module, tobyink @ He can be very helpful sometimes. :)
