[英]Selenium WebDriver “find_element_by_xpath” on WebElement
[英]Loop over list of elements for find_element_by_xpath() by Selenium and Webdriver
使用Python,Selenium和Webdriver,需要隨后使用網頁上的find_element_by_xpath()方法單擊文本找到的元素。
(公司內部網頁,所以無法提供該網址)
通過xpath是最好的方法,但是我想找到並單擊多個文本。
當單獨運行時,它像:
driver.find_element_by_xpath("//*[contains(text(), 'Kate')]").click()
對於多個,這是我嘗試的方法:
name_list = ["Kate", "David"]
for name in name_list:
xpath = "//*[contains(text(), '"
xpath += str(name)
xpath += "')]"
print xpath
driver.find_element_by_xpath(xpath).click()
time.sleep(5)
print xpath的輸出看起來還不錯,但是硒說:
common.exceptions.NoSuchElementException
您可以如下簡化代碼:
for name in name_list:
driver.find_element_by_xpath("//*[contains(text(), '%s')]" % name).click()
要么
for name in name_list:
try:
driver.find_element_by_xpath("//*[contains(text(), '{}')]".format(name)).click()
except:
print("Element with name '%s' is not found" % name)
使用字符串格式。 將占位符放入xpath字符串中,並用一個變量值填充它:
name_list = ["Kate", "David"]
for name in name_list:
xpath = "//*[contains(text(),'{}')]".format(name)
driver.find_element_by_xpath(xpath).click()
嘗試這個:
name_list = ["Kate", "David"]
for name in name_list:
xpath = "//*[contains(text(), '" + str(name) + "')]" # simplified
print xpath
list = driver.find_elements_by_xpath(xpath) # locate all elements by xpath
if len(list) > 0: # if list is not empty, click on element
list[0].click() # click on the first element in the list
time.sleep(5)
這樣可以防止拋出
common.exceptions.NoSuchElementException
注意:還請確保您使用正確的xPath。
