Subject: Add support for [attr!="value"] selector (attribute not equal)
X-Git-Tag: release_0.009004~9^2~6
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=catagits%2FHTML-Zoom.git;a=commitdiff_plain;h=24725e7b32b680b376c06b1f9d641ec11fc1d067

Add support for [attr!="value"] selector (attribute not equal)

http://api.jquery.com/attribute-not-equal-selector/

  Description: Select elements that either don't have the specified
  attribute, or do have the specified attribute but not with a certain
  value.

  This selector is equivalent to :not([attr="value"]).
