How can i get only text in scrapy selector in python

I hope you are doing well.

<ul>
  <li>
    <s>Title:</s>
    De Aardappeleters
  </li>
  <li>
    <s>Dimensions:</s>
    82 x 114 cm
  </li>
  <li>
    <s>Media:</s>
    canvas
  </li>
  <li>
    <s>Style:</s>
    Realism
  </li>
  <li>
    <s>Date:</s>
    1885
  </li>              ______
  <li>                     |
    <s>Genre:</s>          | It is located on a page of the website here
    Modern                 |
  </li>              ______| 
</ul>

I have an HTML block☝ that I want to receive a text from li. But unfortunately, this li has no class or ID that I can select.This block is for a site.

  <li>
    <s>Genre:</s>
    Modern
  </li>

I want to select the genre list and get the text.👇

Modern

The main problem here is that this block is different on another page.👇

<ul>
  <li>
    <s>Title:</s>
    De Aardappeleters
  </li>
  <li>
    <s>Dimensions:</s>
    82 x 114 cm
  </li>
  <li>
    <s>Media:</s>
    canvas
  </li>              ______
  <li>                     |
    <s>Genre:</s>          |And it is located here on another page.
    Modern                 |
  </li>              ______| 
  <li>
    <s>Style:</s>
    Realism
  </li>
  <li>
    <s>Date:</s>
    1885
  </li>
</ul>

OriginalTagFind = layout.css('article ul li s::text').getall()
    
TitleOriginal = [tag.strip() for tag in OriginalTagFind if tag.startswith('Genre:')]

In my opinion, if I come to the place I have selected and print the text of the mother's list with Next Sibiling. is it possible؟

Solution

With a css selector you can use:

'li:has(s):contains("Genre:")::text'

With an xpath selector you can use:

"//li[s[contains(text(), 'Genre')]]/text()"

I have demonstrated using both with your example below:

In [1]: html = """<ul>
   ...:   <li>
   ...:     <s>Title:</s>
   ...:     De Aardappeleters
   ...:   </li>
   ...:   <li>
   ...:     <s>Dimensions:</s>
   ...:     82 x 114 cm
   ...:   </li>
   ...:   <li>
   ...:     <s>Media:</s>
   ...:     canvas
   ...:   </li>
   ...:   <li>
   ...:     <s>Style:</s>
   ...:     Realism
   ...:   </li>
   ...:   <li>
   ...:     <s>Date:</s>
   ...:     188
   ...:   </li>
   ...:   <li>
   ...:     <s>Genre:</s>
   ...:     Modern
   ...:   </li>
   ...: </ul> """

In [2]: selector = scrapy.Selector(text=html)

In [3]: ''.join(selector.xpath("//li[s[contains(text(), 'Genre')]]/text()").getall()).strip()
Out[3]: 'Modern'

In [4]: ''.join(selector.css('li:has(s):contains("Genre:")::text').getall()).strip()
Out[4]: 'Modern'
