String transversePage(Event event, String attribute){
		Element findElm = ((event.target) as Element);

		String name;
		if(findElm.getAttribute('$attribute') != null){
			name = findElm.getAttribute('$attribute');
		} else {
			for(int i = 0; i<=findElm.children.length;i++) {
				if (findElm != null) {
					if (findElm.children.length != i) {
						if (findElm.children[i] != null) {
							if (findElm.children[i].getAttribute('$attribute') != null) {
								name = findElm.children[i].getAttribute('$attribute');
								break;
							}
						}
					}
				}

		return name;
	}

It checks the element that was clicked, returns if the target attribute was found on clicked element or scales down the children of whatever was clicked and returns the attribute.
