使用 BeautifulSoup 从 h1 获取文本

Question

我被要求从 web 中获取产品名称。

我被要求得到这个文本：

精工 5 自动男士钢质复古日本制造黑色表盘手表运行订单 K

这是我的 BeautifulSoup 代码：

soup = BeautifulSoup(get.text, 'lxml')

company = soup.select('h1.it-ttl')[0].text.strip()
print(company)

代码中的 HTML 是：

<h1 class="it-ttl" id="itemTitle" itemprop="name">
<span class="g-hdn">Details about   
</span> 
SEIKO 5 AUTOMATIC MENS STEEL VINTAGE JAPAN MADE BLACK DIAL WATCH RUN ORDER K
</h1>

而不是所需的文本，我得到这个：

详细信息 SEIKO 5 AUTOMATIC Mens STEEL VINTAGE JAPAN MADE BLACK DIAL WATCH RUN ORDER K

如何仅提取产品名称？

soup = BeautifulSoup(get.text, 'html.parser')

company = soup.select('h1.it-ttl')[0].text.strip()
span_text = soup.select('span.g-hdn')[0].text.strip()

print(company)
print(span_text)
print(company.lstrip(span_text))

由于 span 标签嵌套在 h1 标签中，因此必要的步骤是提取 span 文本，并使用 lstrip 方法将其从 h1 标签中删除。

Answer 2

您可以在<span>标记之后想要下一个兄弟。 我在 Chrome DevTools 控制台中运行了以下命令以从列表中获取所需的文本：

> document.querySelector("#itemTitle > span").nextSibling
< " SEIKO 5 AUTOMATIC MENS STEEL VINTAGE JAPAN MADE BLACK DIAL WATCH RUN ORDER K"

您可以使用 Python 的lstrip()方法删除前导空格； nextSibling是 Beautiful Soup 中的next_sibling （ 在此处记录）。
