Could someone summarize the pros and cons of HXT versus HaXml versus HSX?
From my perspective (therefore perhaps important but hardly comprehensive), HXT vs HaXml:
HXT provides arrows. The con is you have to learn arrows. The pro is the arrows provided have the same capability as monads of state and IO. Dually, HaXml does not provide arrows or equivalent. The provided functions of type "Content -> [Content]" ("Content" is the node type) are not very flexible or helpful if you want to thread a state through a parse tree, e.g., a recent question in haskell-cafe on how to insert random numbers as attribute values into a document using HaXml. (I lied about the con of HXT. You don't have to learn arrows if you really resist --- monads of the same capability are provided too.) I have no comment on HSX, and you already know the language vs library contrast.
