I'm new to Haskell and am trying to use the SAX module to parse an XML file. I'm using the following code: module FPHParser where import Data.Text as Text import Data.Maybe import Text.XML.LibXML.SAX as SAX import System.IO f :: IO (Parser IO) f = do let g = do putStrLn ("g called.") return True let h msg = do putStrLn (Text.unpack msg) return False p <- SAX.newParserIO (Just (Text.pack "test.xml")) SAX.setCallback p SAX.reportError h SAX.setCallback p SAX.parsedBeginDocument g SAX.parseComplete p return p and am getting the following error when I parse a file with the following contents: <?xml version="1.0"?> <html/> [This is the error] "Extra content at the end of the document" This error seems to be coming from the LibSAX library, which is a C library. But I think that my error is in my code, as the file is valid XML. Any help would be greatly appreciated!
