Плохой вариант...
Если выгружать так уже вот так

var obj=[
	{
		name: 'Arts',
		dir: '/arts/',
		child: [
			{
				name: 'Animation',
				dir: '/arts/animation/',
				child: [
					{
						name: 'Anime', 
						dir: '/arts/animation/anime/'
					},
					{
						name: 'Artists', 
						dir: '/arts/animation/artists/'
					}
				]
			}
		]
	},
	{
		name: 'Business',
		dir: '/business/',
		child: [
			{
				name: 'Accounting',
				dir: '/business/accounting/',
				child: [
					{
						name: 'Associations', 
						dir: '/business/accounting/associations/'
					},
					{
						name: 'Business-to-Business', 
						dir: '/business/accounting/business-to-business/'
					}
				]
			}
		]
	}
];

Т.о. можно будет сразу работать с данными на странице...
