使用beautifulSoup，Python在h3和div标签中刮取文本 [英] Scraping text in h3 and div tags using beautifulSoup, Python
问题描述
我对python，BeautifulSoup，Selenium等没有任何经验，但是我很想从网站上抓取数据并将其存储为csv文件. 我需要的单个数据样本编码如下(一行数据).
I have no experience with python, BeautifulSoup, Selenium etc. but I'm eager to scrape data from a website and store as a csv file. A single sample of data I need is coded as follows (a single row of data).
<div class="box effect">
<div class="row">
<div class="col-lg-10">
<h3>HEADING</h3>
<div><i class="fa user"></i> NAME</div>
<div><i class="fa phone"></i> MOBILE</div>
<div><i class="fa mobile-phone fa-2"></i> NUMBER</div>
<div><i class="fa address"></i> XYZ_ADDRESS</div>
<div class="space"> </div>
<div style="padding:10px;padding-left:0px;"><a class="btn btn-primary btn-sm" href="www.link_to_another_page.com"><i class="fa search-plus"></i> more info</a></div>
</div>
<div class="col-lg-2">
</div>
</div>
</div>
我需要的输出是
Heading,NAME,MOBILE,NUMBER,XYZ_ADDRESS
我发现这些数据没有ID或类，但仍以常规文本形式出现在网站中. 为此，我分别尝试使用BeautifulSoup和Python Selenium，在这两种方法中我都被困于提取方法，因为我没有看到任何教程，却引导我从这些方法和标签中提取文本
I found those data don't have a id or class yet being in website as general text. I'm trying BeautifulSoup and Python Selenium separately for that, where I got stuck to extract in both the methods as no tutorials I saw, guided me to extract text from these and tags
我的代码使用BeautifulSoup
My code using BeautifulSoup
import urllib2
from bs4 import BeautifulSoup
import requests
import csv
MAX = 2
'''with open("lg.csv", "a") as f:
w=csv.writer(f)'''
##for i in range(1,MAX+1)
url="http://www.example_site.com"
page=requests.get(url)
soup = BeautifulSoup(page.content,"html.parser")
for h in soup.find_all('h3'):
print(h.get('h3'))
我的硒代码
import csv
from selenium import webdriver
MAX_PAGE_NUM = 2
driver = webdriver.Firefox()
for i in range(1, MAX_PAGE_NUM+1):
url = "http://www.example_site.com"
driver.get(url)
name = driver.find_elements_by_xpath('//div[@class = "col-lg-10"]/h3')
#contact = driver.find_elements_by_xpath('//span[@class="item-price"]')
# phone =
# mobile =
# address =
# print(len(buyers))
# num_page_items = len(buyers)
# with open('res.csv','a') as f:
# for i in range(num_page_items):
# f.write(buyers[i].text + "," + prices[i].text + "\n")
print (name)
driver.close()
推荐答案
您可以使用CSS选择器来查找所需的数据.
在您的情况下，div > h3 ~ div将找到直接位于div元素内并以h3元素开头的所有div元素.
You can use CSS selectors to find the data you need.
In your case div > h3 ~ div will find all div elements that are directly inside a div element and are proceeded by a h3 element.
import bs4
page= """
<div class="box effect">
<div class="row">
<div class="col-lg-10">
<h3>HEADING</h3>
<div><i class="fa user"></i> NAME</div>
<div><i class="fa phone"></i> MOBILE</div>
<div><i class="fa mobile-phone fa-2"></i> NUMBER</div>
<div><i class="fa address"></i> XYZ_ADDRESS</div>
</div>
</div>
</div>
"""
soup = bs4.BeautifulSoup(page, 'lxml')
# find all div elements that are inside a div element
# and are proceeded by an h3 element
selector = 'div > h3 ~ div'
# find elements that contain the data we want
found = soup.select(selector)
# Extract data from the found elements
data = [x.text.split(';')[-1].strip() for x in found]
for x in data:
print(x)
要刮掉标题中的文本.
heading = soup.find('h3')
heading_data = heading.text
print(heading_data)
或者您可以通过使用如下选择器来一次获取标题和其他div元素:div.col-lg-10 > *.这样会在col-lg-10类的div元素内找到所有元素.
Or you can get the heading and other div elements at once by using a selector like this: div.col-lg-10 > *. This finds all elements inside a div element that belongs to col-lg-10 class.
soup = bs4.BeautifulSoup(page, 'lxml')
# find all elements inside a div element of class col-lg-10
selector = 'div.col-lg-10 > *'
# find elements that contain the data we want
found = soup.select(selector)
# Extract data from the found elements
data = [x.text.split(';')[-1].strip() for x in found]
for x in data:
print(x)
