Fast XML/HTML for Haskell: XML TypeLift

Abstract

The paper presents and compares a range of parsers with and without data mapping for conversion between XML and Haskell. The best performing parser competes favorably with the fastest tools available in other languages and is, thus, suitable for use in large-scale data analysis. The best performing parser also allows software developers of intermediate-level Haskell programming skills to start processing large numbers of XML documents soon after finding the relevant XML Schema from a simple internet search, without the need for specialist prior knowledge or skills. We hope that this unique combination of parser performance and usability will provide a new standard for XML mapping to high-level languages.
