[Haskell-cafe] Stuck on HXT basics

[Pēteris Paikens]

Yep, that does seem to be the case - cabal shows "Versions installed:
8.5.4, 9.1.6".
The module referenced in the website example -
Text.XML.HXT.DOM.XmlTreeFilter and function isXText - has only old
packages, so when installing hxt I got version 9.1.6, but from
hxt-filter I got hxt 8.5.4, so that's why the example fails.
