Re: Re: text() word lists

Thank you Mike and David,

Both stylesheets are performing extremely well. I ran them on the complete 
xml version of Hamlet and the results are: 657 milliseconds and 781 
milliseconds -- respectively David's and Mike's transformation. Even though 
my computer was 3GHz 2GB RAM these results are fantastic.

I think, these XSLT 2.0 examples completely disspell the myth that XSLT is 
not to be used for (efficient) text processing.


Cheers,

Dimitre Novatchev.
