How to Use

1. Fetch Raw RSS Feed

curl -s "https://hnrss.org/frontpage" | head -100

2. Parse RSS with xmllint

Extract titles from RSS feed:

curl -s "https://hnrss.org/frontpage" | xmllint --xpath '//item/title/text()' - 2>/dev/null

Extract titles and links:

curl -s "https://hnrss.org/frontpage" | xmllint --format - | grep -E '<title>|<link>' | head -20

3. Get Items with Details

curl -s "https://hnrss.org/frontpage" | xmllint --xpath '//item' - 2>/dev/null | xmllint --format - | head -50

4. Parse Atom Feeds

Atom feeds use <entry> instead of <item>:

curl -s "https://github.com/blog.atom" | xmllint --xpath '//entry/title/text()' - 2>/dev/null

Guidelines

Check feed format: Use head first to see if it's RSS or Atom
Use xmllint: Best tool for XPath queries on XML
Handle errors: Some feeds may be slow or rate-limited
Respect robots.txt: Don't hammer feeds with requests
Cache results: Feeds don't update every second
