Text.XML.HaXml.XmlContent.Haskell
Contents
Description
The class XmlContent is a kind of replacement for Read and Show:
it provides conversions between a generic XML tree representation
and your own more specialised typeful Haskell data trees.
If you are starting with a set of Haskell datatypes, use DrIFT to derive instances of this class for you: http://repetae.net/john/computer/haskell/DrIFT and use the current module for instances of the standard Haskell datatypes list, Maybe, and so on.
If you are starting with an XML DTD, use HaXml's tool DtdToHaskell to generate both the Haskell types and the corresponding instances, but _do_not_ use the current module for instances: use Text.XML.HaXml.XmlContent instead.

Whole-document conversion functions
toXml :: XmlContent a => Bool -> a -> Document () Source
Convert a fully-typed XML document to a string (with or without DTD).
fromXml :: XmlContent a => Document Posn -> Either String a Source
Read a Haskell value from an XML document, ignoring the DTD and using the Haskell result type to determine how to parse it.
readXml :: XmlContent a => String -> Either String a Source
Read a fully-typed XML document from a string.
showXml :: XmlContent a => Bool -> a -> String Source
Convert a fully-typed XML document to a string (without DTD).
fpsShowXml :: XmlContent a => Bool -> a -> ByteString Source
Convert a fully-typed XML document to a ByteString (without DTD).
fReadXml :: XmlContent a => FilePath -> IO a Source
Read an XML document from a file and convert it to a fully-typed Haskell value.
fWriteXml :: XmlContent a => FilePath -> a -> IO () Source
Write a fully-typed Haskell value to the given file as an XML document.
fpsWriteXml :: XmlContent a => FilePath -> a -> IO () Source
Write any Haskell value to the given file as an XML document, using the FastPackedString interface (output will not be prettified).
hGetXml :: XmlContent a => Handle -> IO a Source
Read a fully-typed XML document from a file handle.
hPutXml :: XmlContent a => Handle -> Bool -> a -> IO () Source
Write a fully-typed XML document to a file handle.
fpsHPutXml :: XmlContent a => Handle -> Bool -> a -> IO () Source
Write a fully-typed XML document to a file handle, using the FastPackedString interface (output will not be prettified).
