MiniScalp

This is my learning experiment to build a Haskell HTML scraping interface on top of zenacy-html, inspired by scalpel but with more correct (according to the spec) HTML parsing.

Don't expect this package to be in any form complete or production ready!

Example

module Main (main) where

import Control.Monad
import Data.Maybe
import Data.Text
import MiniScalp.Predicates
import MiniScalp.Query
import MiniScalp.Sources
import MiniScalp.Types

data MensaLine = MensaLine Text [Text] deriving (Show)

mensaScraper :: Scraper [MensaLine]
mensaScraper = chroot ("id" @= "canteen_day_1") $ do
  chroots (tag "tr" @& hasClass "mensatype_rows") $ do
    name <- chroot ("td" @: [hasClass "mensatype"]) text'
    meals <- chroots ("td" @: [hasClass "menu-title"]) text'
    return $ MensaLine name meals

main :: IO ()
main = do
  scraped <- fromJust <$> scrapeFile "mensa.html" mensaScraper
  forM_ scraped $ \(MensaLine name meals) -> do
    putStrLn $ unpack name
    forM_ meals $ \meal -> putStrLn ("  " ++ unpack meal)
    putStrLn ""
