Scraping job postings and locations using Ruby and Nokogiri
Scraping job postings and their locations is a common task for market research or recruitment platforms. Ruby’s Nokogiri library is excellent for parsing HTML and extracting data from job boards or company career pages. Most job listings are structured with job titles, company names, and locations in consistent HTML tags. For dynamic pages, using Ruby alongside Capybara can handle JavaScript-rendered content effectively. Additionally, handling pagination is crucial for scraping all available job postings
require 'nokogiri' require 'open-uri' url = 'https://example.com/jobs' doc = Nokogiri::HTML(URI.open(url)) doc.css('.job-item').each do |job| title = job.css('.job-title').text.strip location = job.css('.job-location').text.strip puts "Job Title: #{title}, Location: #{location}" endFor efficiency, adding error handling and validating extracted data ensures reliability. How do you address frequently changing HTML structures when scraping job data?

To adapt to changing structures, I use flexible CSS selectors or XPath queries. Regularly testing the scraper on the site helps catch changes early.

Saving the scraped data in a database like PostgreSQL allows me to analyze job trends or filter by location and industry efficiently.

To avoid blocks, I use rotating proxies and implement rate-limiting in the scraper. Mimicking human behavior reduces the chances of being flagged.

To avoid IP bans, I rotate proxies and add random delays between requests. These techniques mimic real user behavior and reduce the risk of being flagged.
