calling external code from xalan c
Good afternoon,
Is there documentation for calling external executables from xalan c?
If it's not currently possible would anyone point me toward a good starting
place to create that functionality?
Thanks,
Jay

Thanks Steven, any chance you could point me at some example code to get me
started?
msxml does it similarly to xalan java. You declare a namespace for the c#
functions and prefix function calls with it.
If they're custom functions then you need to provide a reference in a
separate xml file to the assembly(a shared library) that contains the code.
Then it knows to load it into memory at run time.

Jay,
I'm not sure how Microsoft does the linkage. There is no XPath function
in the Xalan-C library to call an external program. Hooks are available
for you to overlay the "function" class used to define XPath functions,
thus allowing you to compile your own custom program linkage. You will
need to compile your own custom XPath function and load it at runtime
into the engine.
I have written several XPath libraries in 'C/C++' that create custom
XPath extension functions. They are not yet released to the general
community.

Steven J. Hathaway

I've used msxml to run c-sharp scripts from an xslt script. I see that the
java version of xalan can run java.
I assume the xalan c version can run java scripts if java is installed.
I also saw there was a project to extend the functions available in xslt.
Is there a function/method to execute an external application? Such as
fork() or system() in c code?

Hi Jay,
What do you mean 'calling external executables' from xalan - C, could you give a more specific example of what you need to achieve?

Scott Yuan
