Malcolm Wallace and Colin Runciman have released version 1.13 of HaXml, a bug fix release of the XML processing library for the Haskell language. According to the web page,
HaXml is a collection of utilities for using Haskell and XML together. Its basic facilities include:
- a parser for XML,
- a separate error-correcting parser for HTML,
- an XML validator,
- pretty-printers for XML and HTML.
For processing XML documents, the following components are provided:
- Combinators is a combinator library for generic XML document processing, including transformation, editing, and generation.
- Haskell2Xml is a replacement class for Haskell's Show/Read classes: it allows you to read and write ordinary Haskell data as XML documents. The DrIFT tool (available from http://repetae.net/~john/computer/haskell/DrIFT/) can automatically derive this class for you.
- DtdToHaskell is a tool for translating any valid XML DTD into equivalent Haskell types.
- In conjunction with the Xml2Haskell class framework, this allows you to generate, edit, and transform documents as normal typed values in programs, and to read and write them as human-readable XML documents.
- Finally, Xtract is a grep-like tool for XML documents, loosely based on the XPath and XQL query languages. It can be used either from the command-line, or within your own code as part of the library.
