find multiple elements by id-CodePudding

I am trying to find multiple elements by their respective ids The elements are named

dcm-reservation-limit-multiple-input-generic-X

with X being the number of elements, it could be:

dcm-reservation-limit-multiple-input-generic-0
dcm-reservation-limit-multiple-input-generic-1
dcm-reservation-limit-multiple-input-generic-2
...
dcm-reservation-limit-multiple-input-generic-10

and the list goes on. I've tried already this code:

pricesToFind = driver.find_elements_by_xpath(".//*[@id='dcm-reservation-limit-multiple-input-generic-']")

without any success, the results always return NULL even if they really exist

piece of HTML to help:

<input _ngcontent-ihk-c34="" autocomplete="off"  maxlength="11" type="text" id="dcm-reservation-limit-multiple-input-variation-0">

the input name is randomly generated by javascript, so it's useless to scrape it via input name

I personally have never used Selenium a lot, but I hypothetically know how to do this. I would use a while loop, and then run it over and over again. (Just letting you know, I have no way to actually test this, as I couldn't find any elements in any website that have those same conditions)

from selenium import webdriver
from selenium.webdriver.common.by import By

browser = webdriver.Firefox()
browser.get("somerandomwebsitehere.com/index.html")

a = 1
while a <= 100:
   element = browser.find_element(By.ID, "dcm-reservation-limit-multiple-input-generic-"   str(a))
   # Do whatever you want to the element
   a = int(a)   1

Hopefully this helps. I make no guarantees that this code will work, but now you have an idea on how to make this happen.

Use contains or starts-with?

pricesToFind = driver.find_elements_by_xpath(".//*[contains(@id,'dcm-reservation-limit-multiple-input-generic-')]")

pricesToFind = driver.find_elements_by_xpath(".//*[starts-with(@id,'dcm-reservation-limit-multiple-input-generic-')]")
