使用xpath检索脚本中的数据

Question

我想检索类别内属性“ ean13”之后的数字：

<script>

    universal_variable['product'] = {
        id: 29363,
        ean13: '4005900288646',
        name: 'Cellular Perfect Skin Cuidado De Día Fp 15',
        brand: 'Nivea',
        price: 13.97,
        old_price: 19.95,
        active: 1,
        categories: 'Cremas Hidratantes y Antiedad, Cuidado Facial, Higiene y Belleza',
        url: 'https://www.ulabox.com/producto/cellular-perfect-skin-cuidado-de-dia-fp-15/29363',
                    image: 'https://static.ulabox.com/media/62855_l1.jpg'
            };

</script>
