Actually, I just noticed it's missing the current element :-\
var selector =
element.ancestors().pluck("nodeName").invoke("toLowerCase").join("
> ");
selector += " > " + element.nodeName; // yup, that's ugly :)
I don't really see how many times you'd need an "exact" selector like
this one to get all nodes with the same "ancestorship" (is that even a
word?), so I don't know how useful that'd be as an Element method.
What would might be a little more useful (but again, not that much, so
I don't know) is something that gets all the children at a specified
level, ignorant of who the intermidiate nodes are.
So on the OP's example, something that would collect all the <b> tags
by calling $(document.body).childrenAt(3);
Element.addMethods({
childrenAt: function(element, level) {
if (level < 1)
return element.previousSiblings().concat(element,
element.nextSiblings());
return element.childElements().map(function(e) {
return e.childrenAt(level - 1);
}).flatten().uniq();
}
});
Something like that might do it (haven't tested it much), but it's
gonna be slow like hell on large trees.
Best,
