每个节点的格式：
{
    attrs: [
        {
            dynamic: undefined,
            start: 5,
            end: 13,
            name: 'id',
            value: '"app"'
        }
    ],
    attrsList: [
        {
            start: 5,
            end: 13,
            name: 'id',
            value: 'app'
        },
        {
            end: 60
            name: "@click"
            start: 44
            value: "{click}"
        }
    ],
    events: {
        click: {

        end: 60,
        dynamic: false,
        value: ''
      }
    },
    attrsMap: {
        class: 'container',
        id: 'app'
          @click: '{click}'
    },
