What you are saying here, is given the element "b", how can you derive
a CSS-style selector that shows the path to that element? Or do you
want to just style up elements that match a certain path when a
certain event occurs?
If the latter, you can do something like:
$$( 'div h1 b' ).invoke( 'setStyle', { color: 'red' } ) // set by CSS properties
$$( 'div h1 b' ).invoke( 'addClassName', 'my-class' ) // just add a class
// the above is shorthand for:
$$( 'div h1 b' ).each( function( element ){
element.setStyle( { color: 'red' } );
element.addClassName( 'my-class' );
});
If you'd like to derive the selector, given an element somewhere in
the DOM, I'm not sure how to do that, but possibly XPATH can aid in
that task.
