[英]Is there a way to use beautiful soup to filter out the product id embedded in the JavaScript
我正在为鞋子创建一个结帐机器人，并希望从html源代码中的JavaScript部分抓取数据。 我宁愿不使用字符串操作，因为它是静态的。 有没有办法使用漂亮的汤或类似的东西来过滤产品信息？
这是一个shopify网站。 我曾考虑过使用findAll（“ script”），但是文本中有很多JavaScript部分，我不愿意硬编码它是哪个脚本部分。
这是原始html中javascript的一部分。 我想获取产品编号，例如“ 9913856852004”和鞋子的尺寸/名称信息。

我想要一些可以动态地从javascript信息中获取ID的东西。
您可以结合使用BeautifulSoup ， json和re 。 如果没有实际的URL，确实很难回答，但是这可能会起作用。 您可以根据自己的特定用例进行定制。
情况1：每种产品使用不同的脚本标签。
