从bs4.element.Tag获取包含JSON的文本(beautifulsoup)

Question

我有一个bs4.element.Tag类型的元素，比如：

<span class="hidden gtm-product-data">
{"id":"716727616125500","name":"chinese whitewine","price":7.99,"brand":"silver heights"}
</span>

span标记包含一个JSON字符串。如何只提取品牌名称(JSON字段brand的值(silver heights？

Answer 1

这就是您需要的吗？

import json
from bs4 import BeautifulSoup
sample = '<span class="hidden gtm-product-data">{"id":"716727616125500","name":"chinese white wine","price":7.99,"brand":"silver heights"}</span>'
soup = json.loads(BeautifulSoup(sample, 'html.parser').find("span").getText())["brand"]
print(soup)

输出：

silver heights
