There's no way to extend the C API to allow for extension functions, since
they rely on classes. You cannot use classes in C, so it's impossible.
There should be no problem writing an Apache module in C++, so you can just
use the XalanTransformer class.
The Xalan extensions we ship with the product are already installed if you
use the C API or the XalanTransformer class.

Please respond to
xalan-dev
Okai, sorry if my question was stupid ... but I am using XalanCAPI to
write an ApacheXSLTModule of my own and I like to install external
function of Xalan extension librairies ( external:FunctionDistinct() ),
or in the future ( in I find a new idea you don't already implement )
build my own extension.
So did I miss something, I'm not an expert in relation between c and
c++, but what do you think is the best:
- extend the xalanCAPI
- use c++ and XalanTransformer to write my module with something
like : http://wolfgang.groogroo.com/apache-cplusplus/
- another solution?
If you find my question really out of Xalan topic, I apologize.
Still many thanks.
Olivier
