如何使用 Selenium 和 Python 提取小计价格

Question

I am using Xpath and having trouble pulling out information I need.

It is basically a Price - Subtotal. The HTML Image is attached, and the xpath code I am using is below. What am I missing? At the end I am looking to get the price value into a string.

w = driver.find_element_by_xpath('//*[@id="order-summary"]/section/section[3]/div/table/tbody/tr[2]/td/span')
print(w.text())

Answer 1

To print the Price - Subtotal text ie $27.99 you can use either of the following Locator Strategies :

• Using css_selector and get_attribute("innerHTML") :

   print(driver.find_element(By.CSS_SELECTOR, "td.total-line__price > span.order-summary__emphasis").get_attribute("innerHTML"))

• Using xpath and text attribute:

   print(driver.find_element(By.XPATH, "//td[@class='total-line__price']/span[contains(@class, 'order-summary__emphasis')]").text)

Ideally you need to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies :

• Using CSS_SELECTOR and text attribute:

   print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "std.total-line__price > span.order-summary__emphasis"))).text)

• Using XPATH and get_attribute("innerHTML") :

   print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//td[@class='total-line__price']/span[contains(@class, 'order-summary__emphasis')]"))).get_attribute("innerHTML"))

• Note : You have to add the following imports:

  from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC
