The hexpat package

[Tags: bsd3, library]

This package provides a general purpose Haskell XML library using Expat to do its parsing ( - a fast stream-oriented XML parser written in C). It is extensible to any string type, with String, ByteString and Text provided out of the box.

Basic usage: Parsing a tree (Tree), formatting a tree (Format).

Other features: Helpers for processing XML trees (Proc), trees annotated with XML source location (Annotated), XML cursors (Cursor), more intelligent handling of qualified tag names (Qualified), tags qualified with namespaces (Namespaced), SAX-style parse (SAX), and access to the low-level interface in case speed is paramount (IO).

The design goals are speed, speed, speed, interface simplicity and modular design.

For examples, see Text.XML.Expat.Tree module. For benchmarks,

INSTALLATION: Unix install requires an OS package called something like libexpat-dev. On MacOSX, expat comes with Apple's optional X11 package, or you can install it from source. To install on Windows, first install the Windows binary that's available from, then type (assuming you're using v2.0.1):

cabal install hexpat --extra-lib-dirs=C:\Program Files\Expat 2.0.1\Bin --extra-include-dirs=C:\Program Files\Expat 2.0.1\Source\Lib

Ensure libexpat.dll can be found in your system PATH (or copy it into your executable's directory).
