BeautifulSoup not parsing other URLs

[giddyhead]

Hello again everyone. The following issue I have currently at hand. The script runs to the second page for example "https://www.startpage.com/lookup/?search=position%202&version=NUM2200" and then return back to the first page of https://www.startpage.com/lookup/?search=position%201&version=NUM2200. I used urljoin to for the pages of the base and relative page but it keep cycling back and forth from page 1 to page 2 and back. Why does it want to do that? What can I do to fix this? thanks

from lxml import etree
import html5lib
import requests
from bs4 import BeautifulSoup

url = "https://www.startpage.com/lookup/?search=position%201&version=NUM2200" 


while True:
     
     request = requests.get(url) #Get URL server status
     
     soup = BeautifulSoup(request.content, 'html5lib') #Pass url content to Soup
     dom = etree.HTML(str(soup)) #Ini etree
     url = urljoin(BASE_URL, dom.xpath('/html/body/div[2]/div/section/div[3]/div/div[2]/section/div[1]/div[1]/div[1]/a')[0].get("href")) #Join Relative and Base for full URL of next Page URL
     print('THis is Next url',url)
   
         
     for a in soup.find_all("span", {'class': re.compile(r'^text')}): #Get Text in Span Class and Filter out specific words
          bltext=a.text
          if bltext == 'cook Book':
               st = bltext.replace('cook  Book','')
          elif bltext == 'Study Tools':
               st = bltext.replace('Study Tools','')
          elif bltext == 'Explore More':
               st = bltext.replace('Explore More','')
          elif bltext == 'WayPlus':
               st = bltext.replace('WayPlus','')
          elif bltext == 'Explore More':
               st = bltext.replace('Explore More','')
          elif bltext == 'Store':
               st = bltext.replace('Store','')

          else:
                        
               print('\n',a.text)
     
               

           #with open(f'{chp}.txt', 'w', encoding='utf-8') as f:
            #f.write(chp+'\n'+i.text)
   
     print('pages',url)

     print('This is url', url)
     
     if url in 'https://www.startpage.com/lookup/?search=position%207&version=NUM2203': #Page to Stop
          break #Break out of loop
