I’ve been scraping the web for years. It’s a love-hate relationship: the thrill of finally pulling the data you need, followed by the despair when the site redesigns and everything breaks. Last month, I hit a wall. I needed to extract product specs from dozens of e-commerce pages. Each page had the same data (name, price, description, dimensions) but the HTML structure varied wildly. Some used <dl>, some <table>, some just <div> soup with inline CSS. My trusty regex and BeautifulSoup pipeline turned into a nightmare of conditional branches.
The regex abyss
I started optimistically. Write a few patterns, test, repeat. But soon my code looked like this:
import re
from bs4 import BeautifulSoup
