[wp-hackers] XHTML Strict Mode

[Jamie Talbot]

Hi,

Thanks for all the pointers regarding validation.

I've added to attribute correction the X-Valid plugin, with the result that it
should now fix unbalanced or non-existent quotes for attributes, warn for
non-existent attributes and warn for required attributes that are not present.
A fully automatic option is available in the code, but not presented to the user
yet, that allows for automatic removal of invalid tags and attributes and
automatic addition of required tags.  The code is a little bigger now, but it
can't be helped if a stripped down parse tree of XHTML must be included...  I'm
thinking that a future version might use XML with an option for switching
DocTypes, but that'll be later rather than sooner!

If errors that cannot be fixed are found, a window pops up containing a listing
of those errors.  It attempts to pretty print the input and output tags as well
so you can see the differences between input and output.  The user can opt to
see an output in any case by checking the Show Results box.

The attribute checking code being new, there are possibly (probably) as few bugs
that need ironing out.  I'd appreciate a bit of testing before it's released to
the unsuspecting masses...

The plugin works one time only, either on "Save" or "Publish".  "Saving and
Continuing" should allow for testing without making any test posts public.

Thanks in advance!
