Since Apple provides the metadata tagging of the words via NSLinguisticTagger, then is this the web equivalent: //dim non-anchor tags $('*').not('a').addClass('dim'); //hightlight anchor tags $('a').addClass('highlight'); If the browser provided the syntax metadata, then I don't see how this example with anchor tags is logically different. This appears to be obvious and trivial, where a patent requires non-obviousness and non-trivialness given the state of the art. The linked demo at https://github.com/macguru/SyntaxCheck https://github.com/macguru/SyntaxCheck also seems to show the trivialness of this.
