Here is code for scraping the product names and prices:įrom bs4 import BeautifulSoup from selenium import webdriver import time url = '' # Change argument to the location you installed the chrome driver # (see selenium installation instructions, or get the driver for your # system from ) driver = webdriver. The product name is in a subdiv with class title, and the price is in a subdiv with the classes pull-right and price. Once the HTML has been by Selenium, each item has a div with class caption that contains the information we want. These are randomly generated at the time of writing the products were an Asus VivoBook (295.99), two Prestigio SmartBs (299 each), an Acer Aspire ES1 (306.99), and two Lenovo V110s (322 and 356). Let's use it on the page to get the product name and the price for the six items listed on the first page. The website has some fake pages to test scraping on. Use driver.page_source to get the HTML as it appears after javascript has rendered it.The driver is typically a Chrome driver, so the page is treated the same way as if you were visiting it in Chrome. Wait for the driver to finish executing the javascript, and changing the HTML.Direct the driver to the URL we want to scrape.Initialize a driver (a Python object that controls a browser window).The steps to Parse a dynamic page using Selenium are: The Python module Selenium allows us to control a browser directly from Python. finalized) HTML to python, and use the same parsing techniques we used on static sites. The easiest way of scraping a dynamic page is to actually execute the javascript, and allow it to alter the HTML to finish the page. Volia! If all you have is a static page, you are done! The straightforward way to scrape a dynamic page Please see theĬompanion informational PEP describing style guidelines for the C code The standard library in the main Python distribution. This document gives coding conventions for the Python code comprising find ( id = 'introduction' ) print ( intro_div. text, 'html.parser' ) # By inspecting the HTML in our browser, we find the introduction # is contained in.

This code demonstrates how to get the Introduction section of the Python style guide, PEP8: Let's start with an example of scraping a static page. This post will outline different strategies for scraping dynamic pages. If you use a parser on a dynamically generated page, you get a skeleton of the page with the unexecuted javascript on it. An Amazon webpage would use Javascript to load the latest reviews from its database. For example, would use Javascript to look up the latest weather.

This is common for sites that update frequently. Only once the Javascript finishes running is the HTML in its final state. The HTML includes Javascript for the browser to execute. I have an overview of BeautifulSoup here.Ī site with dynamic content is one where requesting the URL returns an incomplete HTML. A short example of scraping a static page is demonstrated below. If that's the case, then a parser like BeautifulSoup is all you need. When we request the URL, we get the final HTML returned to us. The Python documentation, wikipedia, and most blogs (including this one) use static content. Webscraping beyond BeautifulSoup and Selenium.This post is part 1 of the "Advanced Scraping" series:
