I'm quite stuck on getting HXT working to do my xml parsing, can you help me to get started? Even in http://www.haskell.org/haskellwiki/HXT#Getting_started:_Hello_world_examples the basic filter example that's given there in section 6: import Text.XML.HXT.Core import Text.XML.HXT.DOM.XmlTreeFilter selectAllText :: ArrowXml a => a XmlTree XmlTree selectAllText = deep isXText fails with the following error message. What could I be doing wrong? Couldn't match expected type `Data.Tree.NTree.TypeDefs.NTree XNode' with actual type `hxt-8.5.4:Data.Tree.NTree.TypeDefs.NTree hxt-8.5.4:Text.XML.HXT.DOM.TypeDefs.XNode' Expected type: a (Data.Tree.NTree.TypeDefs.NTree XNode) XmlTree Actual type: Text.XML.HXT.DOM.XmlTreeTypes.XmlFilter In the first argument of `deep', namely `isXText' In the expression: deep isXText On the other hand, perhaps you can suggest something other than HXT - my needs would be taking "heavy" XML's (a lot of little-neccessary structure, but correctly validated), extracting text tokens from it and outputting them with some light tagsoup annotation.
