[Haskell-cafe] Converting wiki pages into pdf

[mukesh tiwari]

Thank your for reply Daniel. Considering my limited knowledge of web
programming and javascript , first i need to simulated the some sort of
browser in my program which will run the javascript and will generate the
pdf. After that i can download the pdf . Is this you mean ?  Is
Network.Browser any helpful for this purpose ? Is there  way to solve this
problem ?
Sorry for  many questions but this  is my first web application program and
i am trying hard to finish it.

Thank you
Mukesh Tiwari
