What's the best way to parse HTML/XML efficiently with lxml Python? or How do you handle large XML fi

If you're dealing with *huge* XML/HTML files, `iterparse()` is a lifesaver. It parses incrementally, so you don't load the entire file into memory.

Pro tip: Clean up elements you don’t need with `elem.clear()` to save memory.

For HTML, I prefer the `html` module in lxml Python—it’s more forgiving with messy markup. But `etree` is faster for well-formed XML.

Check out the official docs (lxml.de) for advanced optimizations.
