Easy HTML parsing for Haskell
Current Status: Usable and stable. Needs GHC 7.6. Please file bugs!
HandsomeSoup is the library I wish I had when I started parsing HTML in Haskell.
It is built on top of HXT and adds a few functions that make it easier to work with HTML.
Most importantly, it adds CSS selectors to HXT. The goal of HandsomeSoup is to be a complete CSS2 selector parser for HXT.
cabal install HandsomeSoup
Nokogiri, the HTML parser for Ruby, has an example showing how to scrape Google search results. This is easy in HandsomeSoup:
import Text.XML.HXT.Core import Text.HandsomeSoup
main = do let doc = fromUrl "http://www.google.com/search?q=egon+schiele" links >> css "h3.r a" ! "href" mapM_ putStrLn links
let doc = fromUrl "http://example.com"
Easily extract elements usingcss
Here are some valid selectors:doc <<< css "a" doc <<< css "*" doc <<< css "a#link1" doc <<< css "a.foo" doc <<< css "p > a" doc <<< css "p strong" doc <<< css "#container h1" doc <<< css "img[width]" doc <<< css "img[width=400]" doc <<< css "a[class~=bar]" doc <<< css "a:first-child"
Easily get attributes using(!)doc <<< css "img" ! "src" doc <<< css "a" ! "href"
