获取元素值并使用 Python 和 Selenium 进行比较

Question

hi this is my first time with Python and Selenium so please be patient.

I have:

<span id="map_x" class="gr een">36</span>
<span id="map_y" class="green">3</span>

So now I'm trying to comapare this value like that

mapx = window.find_element_by_xpath("/html/body/div[6]/div[57]/div[1]/h1/span[2]")
mapy = window.find_element_by_xpath("/html/body/div[6]/div[57]/div[1]/h1/span[3]")
while int(mapx.get_attribute('value')) != 1 and int(mapy.get_attribute('value')) <= 40:

I want to do a loop while mapx is not 1 and mapy less than 40 but when I'm trying it:

Traceback (most recent call last):
  File "C:\Users\", line 50, in <module>
    while int(mapx.get_attribute('value')) != 1 and int(mapy.get_attribute('value')) <= 40:
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

I will be grateful for any help i was trying many other ways, but it still doesn't working.

Answer 1

Its a valid error. The span tag has no attribute value to extract from get_attribute() . It has only id and class attributes. And if it does not find, it will return None .

You need extract the text from those span tags and compare. Try like below and confirm:

1: You can use .text to extract text from a tag .

while int(mapx.text) != 1 and int(mapy.text) <= 40:

2: You can use get_attribute(innerText) too.

mapx = window.find_element_by_xpath("/html/body/div[6]/div[57]/div[1]/h1/span[2]")
mapy = window.find_element_by_xpath("/html/body/div[6]/div[57]/div[1]/h1/span[3]")
while int(mapx.get_attribute('innerText')) != 1 and int(mapy.get_attribute('innerText')) <= 40:

Instead of Absolute xpath opt for Relative xpaths. If Elements id are unique you can try like below:

mapx = window.find_element_by_id("map_x")
mapy = window.find_element_by_id("map_y")
# OR

mapx = window.find_element_by_xpath("//span[@id='map_x' and @class='gr een']")
mapy = window.find_element_by_xpath("//span[@id='map_y' and @class='green']")

Answer 2

You should use .text if this does not work we can work with get_attribute

do this:

mapx = window.find_element_by_xpath("/html/body/div[6]/div[57]/div[1]/h1/span[2]")
mapy = window.find_element_by_xpath("/html/body/div[6]/div[57]/div[1]/h1/span[3]")
while int(mapx.text) != 1 and int(mapy.text) <= 40:
    do while loop logic here

Also not sure if we have unique id map_x and map_y in HTMLDOM , if we have for

<span id="map_x" class="gr een">36</span>
<span id="map_y" class="green">3</span>

if it happens to be unique in nature, please use

window.find_element_by_id('map_x')

similarly for other elements as well.
