name	attributes	example	output
`tag`	`name`	`div`	`{ type: 'tag', name: 'div' }`
`universal`	-	`*`	`{ type: 'universal' }`
`pseudo`	`name`, `data`	`:name(data)`	`{ type: 'pseudo', name: 'name', data: 'data' }`
`pseudo`	`name`, `data`	`:name`	`{ type: 'pseudo', name: 'name', data: null }`
`attribute`	`name`, `action`, `value`, `ignoreCase`	`[attr]`	`{ type: 'attribute', name: 'attr', action: 'exists', value: '', ignoreCase: false }`
`attribute`	`name`, `action`, `value`, `ignoreCase`	`[attr=val]`	`{ type: 'attribute', name: 'attr', action: 'equals', value: 'val', ignoreCase: false }`
`attribute`	`name`, `action`, `value`, `ignoreCase`	`[attr^=val]`	`{ type: 'attribute', name: 'attr', action: 'start', value: 'val', ignoreCase: false }`
`attribute`	`name`, `action`, `value`, `ignoreCase`	`[attr$=val]`	`{ type: 'attribute', name: 'attr', action: 'end', value: 'val', ignoreCase: false }`
