Setting Up Your Scraping Arsenal
Before we embark on our web scraping adventure, it’s crucial to set up the environment. This section covers the configuration of the Firefox WebDriver, installation of necessary Python packages, and the creation of essential functions.
Prerequisites
– Preparing Your Product List
Before diving into the world of AliExpress reviews scraping, make sure you have your product list ready. Create a CSV file containing ali_id
and woo_id
columns. Each row should represent a product, with ali_id
being the AliExpress product ID and woo_id
as the corresponding WooCommerce ID if you plan to import the reviews to your Woo store.
– Downloading GeckoDriver
To harness the power of Selenium with Firefox, you’ll need GeckoDriver, the Firefox WebDriver. If you haven’t installed it yet, you can download it here. Make sure to place it in a directory accessible by your system.
– Creating an AliExpress Account
To begin, you need an AliExpress account. If you don’t have one, head over to AliExpress and sign up. Don’t worry; it’s a quick and straightforward process.
– Obtaining Your AliExpress Member ID
Once you’ve successfully registered, navigate to the account settings page. Click on “Edit Profile,” where you’ll find your Member ID.
Now, locate the numerical values in the Member ID section. We’ll need this ID for our scraping adventure.
2.1 Importing Libraries
If you haven’t installed Python on your machine, fear not! You can download it from python.org. Follow the installation instructions provided for your operating system.
Our secret weapons for this journey are Selenium and BeautifulSoup. Install them using the following commands:
pip install selenium pip install beautifulsoup4
We begin by importing the necessary libraries. Selenium is our go-to tool for web automation, while BeautifulSoup assists in parsing HTML structures. Additionally, we include modules for handling time, CSV file operations, and more.
# Code snippet for importing libraries from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.firefox.options import Options from selenium.webdriver.firefox.service import Service as FirefoxService from bs4 import BeautifulSoup import time import csv
2.2 Creating a Shared Firefox WebDriver
To interact with AliExpress dynamically, we create a shared Firefox WebDriver instance using Selenium. This instance will facilitate headless browsing, ensuring a seamless and non-intrusive scraping process.
def get_driver(): """ Creates and returns a single shared Firefox WebDriver instance. """ firefox_options = Options() firefox_options.add_argument('-headless') firefox_options.add_argument('user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 12.5; rv:114.0) Gecko/20100101 Firefox/114.0') geckodriver_path = 'driver/firefox/geckodriver' #Replace with the path of the downloaded geckodriver firefox_service = FirefoxService(geckodriver_path) return webdriver.Firefox(service=firefox_service, options=firefox_options)
Now that our arsenal is ready, let’s move on to the next section where the real action begins.
3. Fetching HTML Content
Now that our environment is set up, it’s time to fetch the HTML content of AliExpress product reviews. This section guides you through defining the function responsible for this task and handling potential errors that may arise during the process.
3.1 Defining the Function
In this step, we’ll create a function that navigates to the specified AliExpress product page, iterates through the desired number of review pages, and retrieves the HTML content of each page. The function, get_html_content
, ensures a graceful handling of potential errors.
def get_html_content(driver, url, page_num): try: driver.get(url) driver.implicitly_wait(10) # Set a default implicit wait time all_reviews_html = [] # List to store all collected reviews for page in range(1, page_num + 1): # Wait for the reviews container to be present try: reviews_container_locator = (By.CSS_SELECTOR, "#transction-feedback > div.feedback-list-wrap") WebDriverWait(driver, 20).until(EC.presence_of_element_located(reviews_container_locator)) except Exception as e: print(f"Error waiting for reviews container on page {page}: {str(e)}") break # Execute JavaScript to get the outerHTML of the reviews container reviews_container_script = 'return document.querySelector("#transction-feedback > div.feedback-list-wrap").outerHTML;' reviews_outer_html = driver.execute_script(reviews_container_script) all_reviews_html.append(reviews_outer_html) if page < page_num: # Click the next page button try: next_page_button_locator = (By.CSS_SELECTOR, "#complex-pager > div > div > a.ui-pagination-next.ui-goto-page") WebDriverWait(driver, 20).until(EC.element_to_be_clickable(next_page_button_locator)).click() # Wait for the next page to load time.sleep(10) # Adjust the sleep time based on the time it takes to load the next page except Exception as e: print(f"Error clicking next page button on page {page}: {str(e)}") break # Concatenate all collected reviews into a single string all_reviews_combined = '\n'.join(all_reviews_html) return all_reviews_combined except Exception as e: print(f"Error in get_html_content: {str(e)}") return None
3.2 Handling Errors
Web scraping is an adventure, and like any adventure, we might encounter obstacles along the way. To ensure a smooth journey, our script incorporates error-handling mechanisms. The
function gracefully manages errors, such as missing review containers or difficulties in navigating to the next page.get_html_content
Stay tuned as we move on to the next section, where we’ll delve into parsing the retrieved HTML content.
4. Parsing Reviews with BeautifulSoup
Now that we’ve successfully fetched the HTML content, it’s time to roll up our sleeves and dive into parsing the reviews. This section guides you through understanding the structure of a review element and extracting valuable review data.
4.1 Review Element Structure
Before we extract data, it’s essential to understand how a review is structured in the HTML. In our case, reviews are encapsulated within a div
element with the class
. Nested within this structure are various sub-elements holding information such as user details, ratings, and feedback content.feedback-item clearfix
4.2 Extracting Review Data
With the structure in mind, we proceed to extract valuable information from each review. The
function utilizes BeautifulSoup to navigate the HTML tree and extract relevant data. Here’s a glimpse of the code:parse_reviews
def parse_reviews(html_content, product_id, woo_id): """ Parses the HTML content and extracts review data using BeautifulSoup. """ try: soup_html = BeautifulSoup(html_content, 'html.parser') reviews = [] for review_element in soup_html.find_all('div', class_='feedback-item clearfix'): p_title_box = review_element.find('div', class_='fb-user-info') user_name_span = p_title_box.find('span', class_='user-name') if user_name_span: username_anchor = user_name_span.find('a') if username_anchor: username_text = username_anchor.text.strip() p_main = review_element.find('div', class_='fb-main') rate_info_div = p_main.find('div', class_='f-rate-info') star_view_span = rate_info_div.find('span', class_='star-view') if star_view_span: width_style = star_view_span.find('span')['style'] width_percentage = int(width_style.split(':')[-1].strip('%')) if 0 <= width_percentage < 20: r_star = 1 elif 20 <= width_percentage < 40: r_star = 2 elif 40 <= width_percentage < 60: r_star = 3 elif 60 <= width_percentage < 80: r_star = 4 else: r_star = 5 else: r_star = None p_content = p_main.find('div', class_='f-content') b_rev = p_content.find('dl', class_='buyer-review') b_rev_fb = b_rev.find('dt', class_='buyer-feedback') pic_rev = b_rev.find('dd', class_='r-photo-list') p_img = pic_rev.find('ul', class_='util-clearfix') if pic_rev is not None else None media_list = [img['data-src'] for img in p_img.find_all('li', class_='pic-view-item')] if p_img else None media_links = ','.join(media_list) if media_list else '' productId = woo_id if not None else product_id display_name = username_text display_name = 'Store Shopper' if display_name == 'AliExpress Shopper' else display_name email = "demo@demo.demo" review_data = { 'review_content': b_rev_fb.find('span', class_=None).get_text(strip=True), 'review_score': r_star, 'date': b_rev_fb.find('span', class_='r-time-new').get_text(strip=True), 'product_id': productId, 'display_name': display_name, 'email': email, 'order_id': None, 'media': media_links } reviews.append(review_data) return reviews except Exception as e: print(f"Error in parse_reviews: {str(e)}") return []
This function elegantly navigates the HTML structure and extracts essential information, including review content, score, date, and more.
Stay with us as we continue our journey into automating AliExpress reviews scraping with Python. Next, we’ll explore saving the scraped data into a convenient CSV format.
5. Saving Data to CSV
Congratulations on reaching this point! Now that we’ve mastered the art of extracting reviews, it’s time to preserve our findings. In this section, we’ll guide you through saving the scraped data into CSV files, making it easily accessible and organized.
5.1 Successful Reviews
When reviews are successfully scraped, we want to store them in a structured CSV file. The
function takes care of this process:save_to_csv
# Code snippet for saving successful reviews to CSV def save_to_csv(reviews, filename): with open(filename, 'w', newline='', encoding='utf-8') as csvfile: fieldnames = ['review_content', 'review_score', 'date', 'product_id', 'display_name', 'email', 'order_id', 'media'] writer = csv.DictWriter(csvfile, fieldnames=fieldnames) writer.writeheader() writer.writerows(reviews)
This function creates a CSV file with appropriate headers and populates it with the review data, neatly organized for further analysis or sharing.
5.2 Skipped Reviews
Not all heroes wear capes, and not all reviews are scrapable. Fear not! We gracefully handle scenarios where reviews cannot be fetched, and we save the day by providing a CSV file indicating the skipped reviews:
# Code snippet for saving skipped reviews to CSV def e_save_to_csv(filename, fieldnames): with open(filename, 'w', newline='', encoding='utf-8') as csvfile: writer = csv.DictWriter(csvfile, fieldnames=fieldnames) writer.writeheader() writer.writerow({fieldname: 'null' for fieldname in fieldnames})
This function creates a CSV file for skipped reviews, ensuring that no data is left behind, and our scraping adventure continues seamlessly.
Stay tuned for the final leg of our journey—putting it all together and unleashing the power of Python to automate AliExpress reviews scraping!
6. Automating the Process
We’re almost there! In this section, we’ll unveil the grand finale—automating the entire process. Brace yourself for an exciting ride as we dive into the world of automating AliExpress reviews scraping with Python.
6.1 Reading Product List from CSV
Before we embark on our automated journey, we need a list of products to scrape. The
function comes to our aid, reading product details from a CSV file and preparing them for the upcoming adventure:read_product_csv
def get_correct_url(product_id, ali_member_id): base_url = 'https://feedback.aliexpress.com/display/productEvaluation.htm?v=2&productId=' url = f'{base_url}{product_id}&ownerMemberId={ali_member_id}&page=1' driver = get_driver() try: driver.get(url) driver.implicitly_wait(10) return driver.current_url finally: driver.quit() # Close the driver after use def read_product_csv(csv_filename): products = [] with open(csv_filename, 'r', newline='', encoding='utf-8') as csvfile: reader = csv.DictReader(csvfile) for row in reader: product_id = row.get('ali_id') woo_id = row.get('woo_id') if product_id and woo_id: products.append((product_id, woo_id)) return products
This piece of the puzzle ensures that your script knows exactly which products to target, setting the stage for an efficient and accurate scraping performance.
6.2 Scraping Reviews for Multiple Products
Now, let's orchestrate the grand performance. The scrape_products
function will lead us through the captivating experience of automating reviews scraping for multiple products:
def get_reviews(product_id, woo_id, page_num, ali_member_id): driver = get_driver() if woo_id is None: f_name = product_id else: f_name = woo_id try: url = get_correct_url(product_id, ali_member_id) html_content = get_html_content(driver, url, page_num) reviews = parse_reviews(html_content, product_id, woo_id) if reviews: csv_filename = f'reviews/{f_name}_reviews.csv' save_to_csv(reviews, csv_filename) print(f"Reviews scraped and saved to {csv_filename}") else: e_csv_filename = f'reviews/{f_name}_reviews_skipped.csv' e_save_to_csv(e_csv_filename, fieldnames=['review_content', 'review_score', 'date', 'product_id', 'display_name', 'email', 'order_id', 'media']) print("No reviews found.") finally: driver.quit() def scrape_products(product_list, page_num, ali_member_id, delay_seconds): for product_id, woo_id in product_list: print(f"Scraping reviews for AliExpress ID: {product_id}, WooCommerce ID: {woo_id}") get_reviews(product_id, woo_id, page_num, ali_member_id) print(f"Waiting for {delay_seconds} seconds before the next scraping iteration...") time.sleep(delay_seconds)
In this culmination, the script takes the reins, navigating through your list of products and automating the entire review scraping process. Each function plays a vital role in this dance of automation, bringing us to the grand finale of our AliExpress reviews scraping adventure.
