Which Haskell XML library to use?

Question

I see that there is a few of XML processing libraries in Haskell.

• HaXml seems to be the most popular (according to dons)
• HXT seems to be the most adva

Answer 1

HXT's main problem, aside from the unusual arrow syntax, is performance and memory usage. I have an app that spends 1.2 seconds processing about 1.5MB of XML, consuming about 2.3GB (!) of memory in the process. Libxml2 takes a few milliseconds on the same data. Extracting data via the css function and arrow predicates also seems very slow compared to Libxml2.
