Dear Sirs,

I guess this is a very simple question. How can I convert IO [XmlTree] to just a list of XmlTree?

Quick and dirty answer: unsafePerformIO.

Please don't say that. He's a beginner. You realize that the path of least resistance will be to use it, right? You see why that's not a good thing? Even experts don't use this function. (To the O.P.: don't use it) Luke

That's an easy finding on Hoogle:

http://www.haskell.org/hoogle/?hoogle=IO+a+-%3E+a

Anyhow, as the name suggest, the function is "unsafe", so you better know what you're doing.

Bye,
