python-3.x - 如何从 BeautifulSoup 过滤器结果中删除 div

问题描述

现在我正在尝试从 BeautifulSoup 结果中删除 div 类，如下所示：

response = requests.get(url)
            // success
            cnbeta_article_content = BeautifulSoup(response.content, "html.parser").find("div", {"class": "cnbeta-article-body"})
            // failed
            removed_share_content = BeautifulSoup(cnbeta_article_content, "html.parse").find("div", {"class": "article-share-code"}).decompose()
            result_text = removed_share_content.prettify()
            return result_text

首先从类cnbeta-article-body中获取 div，从过滤结果中删除 div article-share-code，但它似乎不起作用。我应该怎么做才能解决它？这个网址是：https://www.cnbeta.com/articles/tech/1097507.htm

如果您观察，divwith classarticle-share-code是一个子节点。如果删除父节点，所有子节点也会被删除。

因此，如果您运行以下代码，子节点也会被删除

res = requests.get("https://www.cnbeta.com/articles/tech/1097507.htm")
soup = BeautifulSoup(res.text)
soup.find("div", {"class": "cnbeta-article-body"}).decompose()

仅删除divwith 类article-share-code检查以下代码

soup.find("div", {"class": "article-share-code"}).decompose()
