hvr / xml

Haskell XML library

XML

Light-weight library for simple parsing and creation of XML documents. It only depends on base, bytestring and text.

The library primarily uses the String type, which makes it rather inefficient for large files.

Example

{-# LANGUAGE RecordWildCards #-}
import Text.XML.Light

data Package = Package
  { pOrderNo  :: String
  , pOrderPos :: String
  , pBarcode  :: String
  , pNumber   :: String
  }

-- | Create XML from a Package
instance Node Package where
  node qn Package {..} =
    node qn
      [ unode "package_number" pNumber
      , unode "package_barcode" pBarcode
      , unode "order_number" pOrderNo
      , unode "order_position" pOrderPos
      ]
