Common Problems with newspaper3k and How to Overcome Them

The newspaper3k package is a powerful tool for extracting and processing news articles from the web. However, users may encounter several issues. Here's a quick guide to common problems and solutions, with code snippets.

1. Incomplete or Incorrect Article Extraction

Problem

newspaper3k may miss key information like the headline, author, or main text due to varied HTML structures.

Solution

Custom Configuration

import newspaper from newspaper import Config

config = Config() config.memoize_articles = False config.fetch_images = False config.language = 'en'

article = newspaper.Article('https://example.com/article-url', config=config) article.download() article.parse() print(article.title)

Manual Parsing:

from bs4 import BeautifulSoup import requests

url = 'https://example.com/article-url' response = requests.get(url) soup = BeautifulSoup(response.content, 'html.parser') title = soup.find('h1').text print(title)

2. Handling Dynamic Content

Problem

newspaper3k might not capture dynamically loaded content.

Solution

Use Selenium: This does not guarantee that we can collect data from the web page

from selenium import webdriver from newspaper import Article

url = 'https://www.wsj.com/livecoverage/trump-biden-rnc-election-2024?mod=hp_lead_pos7' driver = webdriver.Chrome() driver.get(url) html = driver.page_source driver.quit()

article = Article(url) article.set_html(html) article.parse() print(article.text)

3. Slow Performance on Large Datasets

Problem

Processing large numbers of articles sequentially can be slow.

Solution

Parallel Processing

import newspaper from concurrent.futures import ThreadPoolExecutor

def fetch_article(url): article = newspaper.Article(url) article.download() article.parse() return article

urls = ['https://abcnews.go.com/US/trump-assassination-attempt-investigation-continues-new-details/story?id=112020474', 'https://abcnews.go.com/US/rust-armorer-hannah-gutierrez-seeks-new-trial-after/story?id=112012187'] with ThreadPoolExecutor(max_workers=10) as executor: articles = list(executor.map(fetch_article, urls))

for article in articles: print(article.title)

4. Limited Language Support

Problem

Limited support for non-English languages.

Solution

Custom Parsers and NLP Models

import newspaper from newspaper import Config

config = Config() config.language = 'fr' article = newspaper.Article('https://www.goodmorningamerica.com/news/story/former-nfl-star-terrell-davis-speaks-wrongful-handcuffing-112021507', config=config) article.download() article.parse() print(article.text)

5. Dependency Issues and Installation Problems

Problem

Dependency conflicts during installation.

Solution

Virtual Environments

pip install virtualenv

virtualenv venv

source venv/bin/activate

pip install newspaper3k

Manual Dependency Installation

pip install lxml Pillow pip install newspaper3k

6. Handling Paywalls and Captchas

Problem

Paywalls and Captchas can block scraping.

Solution

Subscription APIs: Use official APIs for subscribed users.
Human Intervention: Semi-automated approaches for Captchas. However, this keeps getting worse, ex: https://2captcha.com/

Conclusion

While newspaper3k is powerful, it has challenges. These code snippets provide solutions to common problems, enhancing the reliability and efficiency of your scraping projects.
