In case icon-arrow2 class is fixed value there you can use the following XPath:

"//li[./*[contains(@class,'icon-arrow2')]]//a"

The complete command is

response.xpath("//li[./*[contains(@class,'icon-arrow2')]]//a/text()").getall()

UPD
After you shared the actual link to that page I can give you better locator.
This will work:

response.xpath("//li[./*[contains(@class,'icon-arrow')]]/a[contains(@href,'mob')]/text()").getall()

UPD2
This will give you Kapaklı Gardıroplar text:

response.xpath("//li[./*[contains(@class,'icon-arrow')]]/a[contains(@href,'gar')]/text()").getall()

UPD3
This will give you Gardıroplar text as you defined:

response.xpath("//li[@class='border-bottom py-10']/a/text()").getall()

The issue you are facing is you’re using a css selector in an xpath statement. Assuming your path is accurate you would need to use the full text of the class.

response.xpath('//ol[@class="nav align-items-center flex-nowrap text-nowrap overflow-auto hide-scrollbar tab-title"]//li[svg[contains(@class,"icon-arrow2")]]/text()').getall()

BTW Prophets answer is the way to go, I just wanted to explain what your code is missing.

Below is the HTML, I am working on and I am trying to get “Gardroplar” text but it return me empty

start with <ol class="nav align-items-center flex-nowrap text-nowrap overflow-auto hide-scrollbar>

<li>
  <a href="/">
    <svg class="icon-home m-0">
      <use
        xlink_href="/_ui/responsive/theme-alpha/images/icons.svg#icon-home"
      ></use>
    </svg>
  </a>
</li>
<li>
  <svg class="icon-arrow2 m-0">
    <use
      xlink_href="/_ui/responsive/theme-alpha/images/icons.svg#icon-arrow1"

My code:

response.xpath('//ol[@class="nav.align-items-center.flex-nowrap.text-nowrap.overflow-auto.hide-scrollbar.tab-title"]//li[svg[contains(@class,"icon-arrow2")]]/text()').getall()
