nr:
I have some XML things to take care of, and I had hoped to use a nice functional language with combinators. But I'm having trouble getting HaXml to do anything useful. Here is a program that I wrote just to read in the XML and prettyprint it. But it fails with an error message. The 'expat' tool 'xmlwf' claims the XML is well formed, and the XML was generated from gpsbabel, a tool I trust to behave properly. And yet:
: nr@curlycoat 10429 ; xmlwf 2006-12-27-backup.gpx : nr@curlycoat 10430 ; $AWD/Main 2006-12-27-backup.gpx Main: Parse error: unexpected EOF
Here is Main.hs:
module Main where import qualified Text.XML.HaXml as X import qualified Text.XML.HaXml.Parse as XP import qualified Text.XML.HaXml.Pretty as XPP import qualified IO import qualified System
load :: String -> IO X.Document load fn = do handle <- IO.openFile fn IO.ReadMode contents <- IO.hGetContents handle IO.hClose handle return $ XP.xmlParse fn contents
main = do [xml] <- System.getArgs d <- load xml IO.putStrLn $ show $ XPP.document $ d
I'm using HaXml version 1.13.2-5 as distributed by Debian, with GHC 6.6.
Does anyone have thoughts or suggestions? Is there software I should prefer to HaXml? (I notice that HaXml does not understand XML Schema, which I seem to be stuck with...)
You might also want to have a peek at HXT, the XML toolbox. That's been used to good effect recently, for a little RSS aggregator: http://cale.yi.org/index.php/HRSS -- Don P.S. Redirected to the -cafe
