    There is Bobby [watchfire.com] which is Java based. It's not perfect but it's good at pointing out possible problems.

    Bobby tests for both W3C WAI [w3.org] or US 508 [section508.gov], but it's not perfect. I don't know of other tools, if anyone else does I'd like to know about them.

    I beleive that Betsie [sourceforge.net] the BBC's screen reader is Perl based, and open-source, but it's a little antiquated and it does struggle with really awful sites.

    I believe that use Perl; hijacks the title tag to show the TLD of the link, if you have your settings configured to add domain details.

    • Thanks for the links will look into them. I did have the TLD flag setting in my preferences, so will have to see if that makes a difference in my next link :)

      Decided a better name for the module might be HTML::Lint::Accessible seeing as it really is just an extension of HTML::Lint [cpan.org].

      • I've used Bobby on and off for a while. It's not perfect, it often says thinks like "have you checked this?" rather than tell you anything specific. As a result it reports both false positives, and misses actual problems, but it's a good first line.

        I think that the more recent HTML Tidy [sourceforge.net] does some WAI checks too. As it's now a c library, and accessabile from Perl, (HTML::Tidy [cpan.org]) that's another avenue to look at.

        At the end of the day, automated tools can only go so far, but they are a good place to start.

        • To be fair, I don't think any automated tool can avoid having false positives or false negatives, barring amazing advances in AI. For example, a tool can't know whether an image is purely decorative (and thus needs an ALT attribute of "") or whether any ALT text is meaningful (as opposed to some mindless combination of filename and file size, as some authoring tools have been known to generate).
          • This is true, it's an automated tool, and it can't know if object on the page is accessible, important or trivial padding. It's a good first line, but that's all.

            Many web automated web page creation tools do produce awful and inaccessible web pages, so at the end of the day all pages need to be checked by hand to be sure that they are good. Like you said simple minded rules in Dreamweaver are not going to make web sites accessible, people need to think for them selves to produce good sites, instead of rel

      Ew, regex based HTML parsing [sourceforge.net]!
