刮时由于<br>标记而使文本分成新行

问题描述

您好，我正在尝试抓取页面和页面中的数据，但由于文本中存在br标签，因此无法在一行中获取预期的数据，因此，数据将移至新行，可能会有所帮助赞赏。

以下是我的代码：

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
import time
import random
import re

driver = webdriver.Chrome(r"C:\Users\Acer\AppData\Local\Programs\Python\python36-32\chromedriver.exe")
with open(r"E:\office\Zoro\Zoro11.txt",'r')as f:
    content = f.readlines()
    content = [x.strip() for x in content]
    currentIndex = 0
    with open(r"E:\office\Zoro\Zoro16.csv",'a')as f1:
        f1.write("Product Url" + "," + "Main category"+"," + "Sub category"+"," + "Leaf category"+","+"Title" + "," + "Prodcutid"+","+"Manufacturer Name" + "," + "Manufacturer's number"+","+"reviews"+","+"Price"+","+"smalldesc"+","+"Product Dimensions"+","+"Main Image"+","+"Sub Image")
        f1.write("\n")
        for link in content[currentIndex:]:
            driver.get(link)
            time.sleep(5)
            aj = driver.find_element_by_class_name('zcl-breadcrumb__list').text.replace("Home\n","").replace("\n",">").replace(",","")
            try:
                title = driver.find_element_by_xpath("//*[@data-za='product-name']").text.replace(","")
            except:
                title = "No title"
            try:
                brand = driver.find_element_by_xpath("//*[@data-za='product-brand-name']").text.replace(","")
            except:
                brand = "No Brand"
            try:
                productid = driver.find_element_by_xpath("//*[@data-za='PDPZoroNo']").text.replace(","")
            except:
                productid = "No productid"

            maincategory = aj[:aj.find(">")]
            Leafcategory = aj[aj.rindex('>')+1:]
            Subcategory = aj[(aj.find(">"))+1:aj.rindex('>')]
            mfrnu = driver.find_element_by_xpath("//*[@data-za='PDPMfrNo']").text.replace(","")
            try:
                mainimage = driver.find_element_by_xpath('//*[@id="app"]/div[3]/div[2]/div/div/main/div[1]/div[3]/div/div[1]/div/div/div/div/div/img').get_attribute('src')
            except:
                mainimage = "No mainimage"
            try:
                price = driver.find_element_by_class_name('product-price__price').text
            except:
                price = "No price"
            try:
                smalldesc = driver.find_element_by_class_name('product-attributes').text.replace("\n",";").replace(","")
            except:
                smalldesc = "No desc"
            try:
                specification = driver.find_element_by_css_selector('.product-specifications__table.table.table-striped').text.replace("\n","").strip()
                print(specification)

            except:
                specification = "No sepcs"
            try:
                productdesc = driver.find_element_by_css_selector('.product-description__text').text.replace(","")
                
            except:
                productdesc = "No productfields"
            f1.write(link + "," + maincategory + "," + Subcategory + ","+ Leafcategory + ","+title + "," + productid + "," + brand + "," + mfrnu + "," + price +"," + smalldesc +"," + specification +"," + productdesc +"," + mainimage +"\n")

在productdesc中的上述代码中，我得到以下输出

Pro Series Swivel Head LED Work Light
  280 lumens
Beam distance 54 meters
Run time 3 hrs

预期输出全部与空格成一行 我用来抓取的链接是https://www.zoro.com/dorcy-pro-s-swivel-head-led-worklght-187-lumen-41-2392/i/G9576141/

解决方法

您似乎只需要更新该行即可阅读说明。像在其他字段中一样添加换行符：

更改此：

productdesc = driver.find_element_by_css_selector('.product-description__text').text.replace(",","")

对此：

productdesc = driver.find_element_by_css_selector('.product-description__text').text.replace("\n",";").replace(","")
