C'mon Daniel! libxslt2!
You're looking for at least 6 months of programming and debugging
full time by someone who know the library and the associated specs.
I suggest you hire Kasimier to implement it if you really need it.
I don't have time, my employeer won't let me get 6 months off for it
and honnestly I don't blame them. Print the set of associated specs,
weight them, print the XPath1/XSLT-1 specs, weight them, It took me
around 1 year to get the latter done, compare the weights, make a
linear estimation and take into consideration experience done with
first
set. Then you can make your own estimation of how long it's gonna take
if you try to do it, or try to get someone to do it for you.
Now can you tell me why you needed that amount of work to be done
other than "I would very much like it" ?
