[英]Webscraping with selenium using python filtering with webdriver.find function
I'm filtering the fixed income products which appears in this website: https://yubb.com.br/investimentos/renda-fixa?investment_type=cdb&months=3&principal=10000000.0&sort_by=minimum_investment我正在过滤本网站上出现的固定收益产品: https : //yubb.com.br/investimentos/renda-fixa?investment_type=cdb&months=3&principal=10000000.0&sort_by=minimum_investment
Basically, the page have some cards and I wanna know for each page how many cards appears.基本上,该页面有一些卡片,我想知道每个页面出现了多少张卡片。 For example, choosing cdb as type and 3 months, it shows 16 cards, but with another input of months or type of product, it may appear less cards.
例如,选择cdb作为type和3months,显示16张卡片,但是如果再输入months或type,可能会出现较少的卡片。
by now, I know how many possible number of pages it will appear looking at "investmentCardContainer__footer", which is a class but the number of cards looks like it shows as style and I dont know how to find it using selenium webdriver.find function.到现在为止,我知道在查看“investmentCardContainer__footer”时会出现多少可能的页数,这是一个类,但卡片的数量看起来像是显示为样式,我不知道如何使用 selenium webdriver.find 函数找到它。
Here's a tip for what i'm looking for:这是我正在寻找的提示:

The idea it's to get this number of cards and use it in a loop to get the cards information aggregated in a vector.这个想法是获取这个数量的卡片并在循环中使用它来获取聚合在向量中的卡片信息。
vetor = ["cdb","lca","lci"]
dataset_boxes =[]
now = time.time()
for i in vetor:
options = Options()
options.add_argument('--headless')
url = 'https://yubb.com.br/investimentos/renda-fixa?investment_type={}&months=12\
&principal=1000000.0&sort_by=net_return'.format(i)
driver = webdriver.Chrome("C:\\Users\\yourpath\\Desktop\\PYTHON\\chromedriver.exe",options=options)
driver.get(url)
time.sleep(1)
num_pages = driver.find_element_by_class_name("investmentCardContainer__footer").text
list_pages = Convert(num_pages)
last_page = int(list_pages[len(list_pages)-3])
driver.quit()
for j in range(1,last_page+1):
url2 = 'https://yubb.com.br/investimentos/renda-fixa?collection_page={}&investment_type={}&months=12\
&principal=1000000.0&sort_by=net_return'.format(j,i)
driver = webdriver.Chrome("C:\\Users\\yourpath\\Desktop\\PYTHON\\chromedriver.exe",options=options)
driver.get(url2)
num_boxes = driver.find_element_by_class_name("investmentCardContainer__body").text
list_boxes = Convert(num_boxes)
dataset_boxes.append(list_boxes)
driver.quit()
print('idk')
later = time.time()
difference = int(later - now)
print('Processo finalizado em {} segundos.'.format(difference))
Use WebDriverWait
and following xpath
to get the no of pages
count.使用
WebDriverWait
并遵循xpath
来获取no of pages
。
print(WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'(//span[@class="page"]//a)[last()]'))).text)
You need to have following imports to execute above code.您需要有以下导入才能执行上述代码。
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
