For example if my business logic takes 300 msec and my xslt trasform
takes 30 msec, I'm happy because even if xslt trasform takes 10% I
have separated data from presentation. The same logic in perl takes
600 msec, and xslt trasform takes always 30 msec or similar and so on.
So I'd like to use saxon in c because it offers xslt2 support but in
the same way I'd like to continue to use c because my business logic
is faster.
This my modest opinion.
Do you make provision for porting saxon in c?
I think you are missing the point here. Performance and separation of
logic have little to do with one another. Some people already have
stressed that there will not be a port to C++, let alone C. Of course, I
cannot talk for Michael, but since .NET and Java together cover close to
99% of the operating systems, including embedded ones, I doubt he will
ever go through the trouble of rewriting everything: the only thing to
gain is a loss of portability, which cannot be considered a gain.
And like you say above: if your business logic take 300 msec and your
xslt transform takes 30 msec, there is nothing more you need to do. Make
sure you cache the compiled stylesheets, that will save you a lot of
overhead.
I have no idea why you think "xslt transform always takes 30 msec",
because there is not such a thing (unless your input is always the same,
in which case you won't need to re-transform, in which case you go down
to 0 msec). XSLT is an interpreted language and transforms certain input
into certain output and each input is different and so is the
performance + running time.
Perl is, like XSLT an interpreted language. Perl will be much faster in
many respects, in other respects, XSLT will be. C will only be faster in
cases where you optimize as much, but you will loose your flexibility.
If you use C for your transformations, you do not need XSLT. Saying that
"XSLT in C" is faster than Perl, sounds like you miss the point that,
regardless your host language, XSLT remains an interpreted language
(like Perl is an interpreted language, and is written C as well).
But if you are so fond of C, you should stick to .NET on Linux, because
.NET itself is written in C++ by the Microsoft guys. Perhaps the same is
true for Mono. Then you have Linux + Mono + .NET + XSLT. Of which all
are written C/C++ (apart from XSLT of course, which is still just XSLT:
an XML file that is interpreted as a declarative language).
