如何使用 Scrapy 从这个元素中获取文本? :: 文本不起作用

How to get the text from this element with Scrapy ? :: text is not working

对于元素中的文本,我们可以使用哪些其他方法?

>>> products.css('h2.entry-title').get()
'<h2 class="entry-title" itemprop="headline"><a href="https://example.com/index.php/2021/12/12/your-20-with-few-clicks-from-stash/" rel="bookmark">Your  With Few Clicks From Stash</a></h2>'

但试图获取文本,你的 20 美元来自 Stash 使用

products.css('h2.entry-title::text').get()

>>> products.css('h2.entry-title::text').get()
>>> 

无效。有什么建议吗?谢谢。

实际上,所需的文本节点 Your With Few Clicks From Stasha tag 下。要获得正确的输出,css 表达式应如下所示:

products.css('h2.entry-title a::text').get().strip()

在 scrapy 中的实现 shell:

In [6]: from scrapy.selector import Selector

In [7]: %paste
html_doc="""
<html>
 <body>
  <h2 class="entry-title" itemprop="headline">
   <a href="https://example.com/index.php/2021/12/12/your-20-with-few-clicks-from-stash/" rel="bookmark">       
    Your  With Few Clicks From Stash
   </a>
  </h2>
 </body>
</html>
"""

## -- End pasted text --

In [8]: sel = Selector(text=html_doc)

In [9]: sel.css('h2.entry-title a::text').get().strip()
Out[9]: 'Your  With Few Clicks From Stash'
