我將此代碼用于抓取問題和 Google People Also Ask 的回答。我想用它來為作家創造想法。
但是我不能準確地得到那個元素，這次我嘗試使用完整的 Xpath，但是使用一些關鍵字它會改變完整的 Xpath 并且它會出錯。
可變順序是問題的質量和我需要抓取的數量。
def get_question(order):
try:
question = driver.find_element(By.XPATH, '/html/body/div[7]/div/div[9]/div[1]/div/div[2]/div[2]/div/div/div[2]/div/div/div[1]/div[' str(order 1) ']/div[2]/div/div[1]/div[2]/span').text
except:
question = ''
print('Xpath question wrong')
return question
def get_answer(order):
try:
answer = driver.find_element(By.XPATH, '/html/body/div[7]/div/div[9]/div[1]/div/div[2]/div[2]/div/div/div[2]/div/div/div[1]/div[' str(order 1) ']/div[2]').get_attribute('outerHTML')
except:
answer = ''
print('Xpath answer wrong')
之后我將使用回圈進行一一一問一答的抓取，如下所示：
if __name__ == '__main__':
quality_question = 5
order = 0
while order <= quality_question:
question = get_question(order)
answer = get_answer(order)
有任何想法在所有情況下都得到準確的問答。當結果的結構不同時，完整的 Xpath 會改變。謝謝您的支持。有什么想法要這樣做嗎？
這是我需要抓取的 Google 網址，您可以嘗試使用搜索查詢“如何制作面包店”

uj5u.com熱心網友回復：
您應該首先構建一個 xpath
//span[text()='People also ask']/../following-sibling::div/descendant::div[@data-hveid and @class and @jsname and @data-ved]
只是弄清楚存在多少問題。
一旦你這樣做了，下一個作業就是點擊它，然后檢索答案。
代碼：
driver = webdriver.Chrome(driver_path)
driver.maximize_window()
driver.implicitly_wait(30)
wait = WebDriverWait(driver, 30)
driver.get("https://www.google.com/search?q=How to make bakery?&source=hp&ei=j0aZYYjRAvja2roPrcWcyAU&iflsig=ALs-wAMAAAAAYZlUn4NMUPjfIpQmrXSmjIDnaWjJXWIJ&ved=0ahUKEwjI1JDn0Kf0AhV4rVYBHa0iB1kQ4dUDCAc&uact=5&oq=How to make bakery?&gs_lcp=Cgdnd3Mtd2l6EAMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBNQAFgAYJMDaABwAHgAgAF-iAF-kgEDMC4xmAEAoAECoAEB&sclient=gws-wiz")
