|
|
|
|
objective:
|
|
- Parse HTML content from RSS feed descriptions
|
|
- Extract and sanitize text content
|
|
- Convert HTML to plain text for display
|
|
|
|
deliverables:
|
|
- HTML to text conversion utility
|
|
- Sanitization function for XSS prevention
|
|
- Updated RSS parser integration
|
|
|
|
steps:
|
|
1. Create `src/utils/html-to-text.ts`
|
|
2. Implement HTML-to-text conversion algorithm
|
|
3. Add XSS sanitization for extracted content
|
|
4. Handle common HTML elements (paragraphs, lists, links)
|
|
5. Update `parseRSSFeed()` to use new HTML parser
|
|
|
|
tests:
|
|
- Unit: Test HTML to text conversion accuracy
|
|
- Integration: Test with HTML-rich RSS feeds
|
|
- Security: Test XSS sanitization with malicious HTML
|
|
|
|
acceptance_criteria:
|
|
- HTML content is converted to readable plain text
|
|
- No HTML tags remain in output
|
|
- Sanitization prevents XSS attacks
|
|
- Links are properly converted to text format
|
|
|
|
validation:
|
|
- Test with podcast descriptions containing HTML
|
|
- Verify text is readable and properly formatted
|
|
- Check for any HTML tag remnants
|
|
|
|
notes:
|
|
- Use existing `decodeEntities()` function from rss-parser.ts
|
|
- Preserve line breaks and paragraph structure
|
|
- Convert URLs to text format (e.g., "Visit example.com")
|
|
- Consider using a lightweight HTML parser like `html-escaper` or `cheerio`
