It looks like you haven't initialized the networking subsystem. See

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 following error on my Windows 7 64 bit:
InternalIOException getAddrInfo: does not exist (error 10093).
Thanks
