Hi Stuart, I was going to suggest the same as Roman, this is a "known problem" on Windows. But the good news is that withSocketsDo is implemented as "id" if you are on Unix, so you could still write multi platform programs without worrying about platforms and preprocessor flags. Hope this helps! Alfredo On 21 January 2014 23:14, Roman Cheplyaka wrote:

Here is the source by the way: {-# LANGUAGE OverloadedStrings #-}

import Network.HTTP.Conduit (simpleHttp) import qualified Data.Text as T import Text.HTML.DOM (parseLBS) import Text.XML.Cursor (Cursor, attributeIs, content, element, fromDocument, child, ($//), (&|), (&//), (>=>))

-- The URL we're going to search url = "http://www.bing.com/search?q=school+of+haskell"

-- The data we're going to search for findNodes :: Cursor -> [Cursor] findNodes = element "span" >=> attributeIs "id" "count" >=> child

-- Extract the data from each node in turn extractData = T.concat . content

-- Process the list of data elements processData = putStrLn . T.unpack . T.concat

cursorFor :: String -> IO Cursor cursorFor u = do page <- simpleHttp u return $ fromDocument $ parseLBS page

-- test main = do cursor <- cursorFor url processData $ cursor $// findNodes &| extractData

I copied and pasted some html parsing demo source from FP School.

While the code works on the FP demo site (in the IDE), I get the

Thanks
