Selenium | How to iterate | TypeError: 'WebElement' object is not iterable
Selenium | How to iterate | TypeError: 'WebElement' object is not iterable
请在下面找到我要获取行的附加屏幕截图，即所有推文行。
我正在努力研究如何迭代和获取所有行。
下面的代码我试过了。
driver.get("https://www.trackmyhashtag.com/")
form = driver.find_element_by_xpath("//*[@class='container']")
usrinput = driver.find_element_by_xpath('/html/body/header/div[2]/div/div[2]/form/div/div[1]/input')
usrinput.clear()
usrinput.send_keys("india")
loginbt = driver.find_element_by_xpath('/html/body/header/div[2]/div/div[2]/form/div/div[2]/button')
loginbt.click()
time.sleep(5)
ad = driver.find_element_by_xpath('/html/body/div[1]/div[1]/div/div[3]/div/div/div/button')
ad.click()
time.sleep(5)
element = driver.find_element_by_xpath('/html/body/aside/nav/div/ul/li[2]/a')
actions = ActionChains(driver)
actions.move_to_element(element).perform()
actions.click().perform()
time.sleep(5)
ad=wait.until(driver.find_element_by_xpath('/html/body/div[1]/div[1]/div/div[3]/div/div/div/button'))
row = driver.find_element_by_xpath('/html/body/div[1]/div[1]/div[1]/div[5]/div/div/div/div[2]/div')
for i in row:
i.get_attribute('td')
print(i)
print("inside it")
要获取所有推文行，您可以使用此
rows = driver.find_elements_by_xpath("//tr[@role='row' and(@class)]")
现在要获取推文名称，您可以这样做：
actions = ActionChains(driver)
rows = driver.find_elements_by_xpath("//tr[@role='row' and(@class)]")
for i in range(1,len(rows)+1):
row = driver.find_element_by_xpath("(//tr[@role='row' and(@class)])[" + str(i) + "]")
actions.move_to_element(row).perform()
time.sleep(1)
row = driver.find_element_by_xpath("(//tr[@role='row' and(@class)])[" + str(i) + "]")
name = row.find_element_by_xpath(".//div[@class='tweet-name']").text
content = row.find_element_by_xpath(".//td[2]").text
date = row.find_element_by_xpath(".//td[2]").text
impressions = row.find_element_by_xpath(".//td[6]").text
要使用 actions，您需要导入
from selenium.webdriver.common.action_chains import ActionChains
您需要使用 find_elements_by_xpath 而不是 find_element_by_xpath
rows = driver.find_elements_by_xpath('//table[@id='tweets_table']//tr//td')
for row in rows:
print(row.text)
这个异常：
类型错误：'WebElement'对象不可迭代
是因为你应该使用 find_elements 其中 returns 一个列表，并且可以迭代，而不是 find_element 其中 returns 一个单一的网络元素。
