"Unable to find element error" even if this exists-CodePudding

is there a way to click this "like" button on the "Like 4 Like" site? Because I can't do it via xpath or full xpath, not even using "webdriverwait". I always get the error Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id='likebutton52335" } (Session info: chrome=100.0.4896.127) even though I know it exists.

                TEST = 0
                while TEST < 1:
                likebutton = driver1.page_source
                time.sleep(10)
                #BUTTON = re.findall('id="/html/body/div[9]/div/div/div/div[1]/div/div/div[4]/div/div[2]/div[2]/div[4]/div/div/div[1]/div[1]/span[5]"', likebutton, re.MULTILINE)
                BUTTON = re.findall('id="likebutton(. ?)"><a', likebutton, re.MULTILINE)
                if BUTTON == []:
                    TEST  = 1
                for num in BUTTON:
                    try:
                        button = 'likebutton%s' % num
                        ref = "//*[@id='%s']" % button
                        time.sleep(3)
                        #WebDriverWait(driver1, 10).until(EC.element_to_be_clickable((By.XPATH, ref))).click()
                        #wait.until(EC.element_to_be_clickable((By.XPATH, "//span[contains(text(),'Like')]"))).click()
                        driver1.find_element(By.XPATH, ref).click()
                        #driver1.find_element(By.XPATH, "/html/body/div[9]/div/div/div/div[1]/div/div/div[4]/div/div[2]/div[2]/div[4]/div/div/div[1]/div[1]/span[5]").click()
                        time.sleep(2)
                        window_after = driver1.window_handles[1]
                        driver1.switch_to.window(window_after)
                        time.sleep(1)
                        likebutton = driver1.page_source
                        time.sleep(3)

CodePudding user response：

Your problem is inside your regex!

Actually your regex is configured to get:

id="(number"...)"<a

That explain this value for the regex in the error: 
52335"

So you get other parameter from the HTML tag.

You need to change your regex by:

id="likebutton(. ?)"

Like that you get the content between doubles quotes.

Result:

      TEST = 0
      while TEST < 1:
                likebutton = driver1.page_source
                time.sleep(3)
// This Line was modified
                BUTTON = re.findall('id="likebutton(. ?)"', likebutton, re.MULTILINE)

                        ref = "//*[@id='%s']" % button
                        driver1.find_element(By.XPATH, ref).click()
