python selenium通过相对xpath找到一个按钮

Question

我想获取卖家的联系方式（电子邮件和电话号码）。

[<ul class="_17qy1 _1rj80 _1sql3 _3a4zn"><li><a class="_w7z6o" data-box-name="AskSellerClick" href="#zadaj-pytanie" rel="nofollow">pytanie do sprzedającego</a></li><li><div>pjp*******@******<!-- --> (<button class="_w7z6o _ypulx" data-box-name="SellerEmailShow" type="button">pokaż</button>)</div></li></ul>, <ul class="_17qy1 _1rj80 _1sql3 _3a4zn"><li><div>+48 *** *** ***<!-- --> (<button class="_w7z6o _ypulx" data-box-name="SellerMobileShow" type="button">pokaż</button>)</div></li></ul>]

以下操作无效：

click_on_button = wd.find_elements(By.CLASS_NAME, 'SellerMobileShow')

click_on_button = wd.find_elements_by_css_selector('body > div.main-wrapper > div:nth-child(3) > div > div > div:nth-child(10) > div > div > div > div > div:nth-child(5) > div:nth-child(2) > div > div > div._t2hyt._l7nkx._r6475._1rcax._nyhhx._1bo4a._r8zxu._1ar9d._62fe8_pdZjg._62fe8_CY37T._62fe8_24sRD > div > div._9f0v0._1xzdi._ai5yc._5d6n2._1h7wt._62fe8_1ibzI > section > div > div > div > div:nth-child(2) > div > div > div._1bo4a._xu6h2._m7qxj._1q55c > section:nth-child(2) > div > div > div:nth-child(2) > ul > li:nth-child(1) > div > button')

find_element_by_xpath('/html/body/div[2]/div[3]/div/div/div[10]/div/div/div/div/div[5]/div[2]/div/div/div[2]/div/div[2]/section/div/div/div/div[2]/div/div/div[2]/section[2]/div/div/div[1]/ul/li[2]/div/button')

当拍卖链接更改时，从 Chrome 或 CSS 选择器复制的 Xpath 是否停止工作？ 将如何确定相对的 Xpath 或者如何单击这三个按钮查看卖方的数据？

Answer 1

email = driver.find_element_by_xpath("//*[@data-box-name=\"SellerEmailShow\"]/..")
print(email.text)
phone = driver.find_element_by_xpath("//*[@data-box-name=\"SellerMobileShow\"]/..")
print(phone.text)

您可以使用按钮作为参考

如果出现计时问题，您可以使用显式等待

email = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located(
        (By.XPATH, "//*[@data-box-name=\"SellerEmailShow\"]/.."))
)

Answer 2

要打印您需要为visibility_of_element_located() 诱导WebDriverWait 的文本，您可以使用以下基于xpath 的Locator Strategies：

• 打印pjp*******@****** (pokaż)：

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[contains(., 'pytanie do sprzedającego')]//following::li[1]/div"))).text)
  

• 打印+48 *** *** *** (pokaż)：

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[contains(., 'pytanie do sprzedającego')]//following::li[2]/div"))).text)

要打印完整的电子邮件和电话，即pjpauli101@aol.de和+48 501 433 898，您可以使用关注xpath 基于Locator Strategies：

• 代码块：

  driver.get("https://allegro.pl/oferta/faller-170601-plyta-dekoracyjna-droga-brukowana-h0-9303217744#aboutSeller")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@data-role='accept-consent']"))).click()
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@data-box-name='SellerEmailShow']"))).click()
  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[@data-box-name='SellerEmailClick']"))).text)
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@data-box-name='SellerMobileShow']"))).click()
  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//li[.//a[@data-box-name='SellerEmailClick']]//following::li[1]/div"))).text)
  

• 控制台输出：
