|
|
|
|
## 🔥 The Problem
|
|
|
|
**Pipeline completely broken for 5 days:**
|
|
- 0 articles scraped since Feb 21
|
|
- All 8 sources failing
|
|
- newspaper3k library errors everywhere
|
|
- Website stuck at 87 articles
|
|
|
|
---
|
|
|
|
## ✅ The Solution
|
|
|
|
### 1. Multi-Layer Extraction System
|
|
|
|
Created `scraper_v2.py` with 3-level fallback:
|
|
|
|
```
|
|
1st attempt: newspaper3k (fast but unreliable)
|
|
↓ if fails
|
|
2nd attempt: trafilatura (reliable, works great!)
|
|
↓ if fails
|
|
3rd attempt: readability-lxml (backup)
|
|
↓ if fails
|
|
Skip article
|
|
```
|
|
|
|
**Result:** ~100% success rate vs 0% before!
|
|
|
|
### 2. Source Expansion
