Description:

The Haskell XML Toolbox bases on the ideas of HaXml and HXML, but
introduces a more general approach for processing XML with Haskell.
The Haskell XML Toolbox uses a generic data model for representing XML
documents, including the DTD subset and the document subset, in
Haskell. It contains a validating XML parser, a HTML parser, namespace
support, an XPath expression evaluator, an XSLT library, a RelaxNG
schema validator and funtions for serialization and deserialization
of user defined data. The library makes extensive use of the arrow
approach for processing XML.
