Python Selenium是否将数据存储到CSV中的特定列?

我有两份印刷品要写入一个 CSV 文件中,分别写入 A 列和 B 列中

我的问题是,当我同时打印(第一张和第二张)时,我只能得到一个元素,我猜多次,因为它不在循环内。

print((text), (link[0:-9]))

结果:

LMFCIIC PWFERT-BK
LMFCIIC PMFEP-BK
LMFCIIC LMF8CC-BL
LMFCIIC PMFEP-GY
LMFCIIC ASPCP-NV
LMFCIIC LWBASK-PK
LMFCIIC LWBATA-PK
LMFCIIC LWBATOP-PK
LMFCIIC LMF8CC-RD

我的第一次打印是这样的:我想将其打印到列 A

PWFERT-BK
PMFEP-BK
LMF8CC-BL
PMFEP-GY
ASPCP-NV
LWBASK-PK
LWBATA-PK
LWBATOP-PK
LMF8CC-RD

我的第二张照片看起来像这样:我想将其打印到列 B

LMFCIIC


LWBASK
LWBATA
LWBATOP
LMFCIIC

这是我的完整代码:

from bs4 import BeautifulSoup
from selenium import webdriver
import html5lib
import time
import requests

driver_path = '/usr/local/bin/chromedriver 2'
driver = webdriver.Chrome(driver_path)
driver.implicitly_wait(10)

driver.get('https://www.tenniswarehouse-europe.com/zzz/producttracker_bl.html?ccode=SWIMG030')
try:
    iframe = driver.find_elements_by_tag_name('iframe')
    for i in range(0, len(iframe)):
            f = driver.find_elements_by_tag_name('iframe')[i]
            driver.switch_to.frame(i)
            #  your work to extract link
            text = driver.find_element_by_tag_name('body').text
            text = text.replace("Code: ","")
            text = text.replace("No Copy Images to TW Server","")
            print(text)
            driver.switch_to_default_content()
finally:
    driver.quit()

resp = requests.get('https://www.tenniswarehouse-europe.com/zzz/producttracker_bl.html?ccode=SWIMG030')
soup = BeautifulSoup(resp.text,"lxml")
for frame in soup.findAll('img'):
    link = (frame['src'])
    link = link.split('=')[1] 
    print ((link[0:-9]))
  • 我使用了 www.example.com ,因为无法从我的网络访问该链接

编写driver.switch_to.frame(i)时,基本上就是在访问iframe html元素。像普通的html页面一样,您也可以访问其内部元素。

您上一个问题中的iframe就像

<body>
<a href="http://www.test2.com" target="_blank">
<img src="https://img2.test2.com/LWBAD-1.jpg"></a>
<br/>Code: LWBAD

您可以通过以下方式轻松访问图片网址

img_src = driver.find_element_by_tag_name('img').get_attribute('src')

并将其存储在csv文件中

代码:

from bs4 import BeautifulSoup
from selenium import webdriver
import html5lib
import time
import requests
import csv

driver_path = '/usr/local/bin/chromedriver 2'
driver = webdriver.Chrome(driver_path)
driver.implicitly_wait(10)

driver.get('https://www.example.com')

iframe = driver.find_elements_by_tag_name('iframe')
images = driver.find_elements_by_tag_name('img')
with open('file_name.csv', 'w', newline='') as csvfile:
    field_names = ['text', 'src']
    writer = csv.DictWriter(csvfile, fieldnames=field_names)
    writer.writerow({'text': 'text', 'src': 'src'})
    for i in range(0, len(iframe)):
        f = driver.find_elements_by_tag_name('iframe')[i]
        img_src = images[i].get_attribute('src')

        # do the src splitting here
        img_src = img_src.split('=')[1]

        driver.switch_to.frame(i)

        text = driver.find_element_by_tag_name('body').text


        text = text.replace("Code: ", "")
        text = text.replace("No Copy Images to TW Server", "")
        print(text)
        writer.writerow({'text': text, 'src': img_src})

        driver.switch_to_default_content()
driver.quit()
