Xalan in Apache 2.0 module

[David Vos]

I'm working on an Apache 2.0 module that performs xslt.  I would like to
use Xalan C++ if possible, though I am open to using other libraries if
necessary.

I've gotten Xalan C++ to work under Apache 1.3.  Now, when I'm porting the
module to Apache 2.0, it crashes when I call transform().

Does anyone have any simple, bare-bones examples of Apache 2.0 modules
that use Xalan C++?

I also found in the archives a mention that Xalan has a C API.  Could
someone give me a reference for it?  I only need to do a simple
transformation using xslt parameters.  (Preferrably using a Xalan output
handler so that I can send the result to the client).  Apache might like
it better if I do the whole project in C instead of C++.

Here is an example function that I can call from my apache handler:
void test() {
    XMLPlatformUtils::Initialize();
    XalanTransformer::initialize();
    XalanTransformer        theXalanTransformer;
    int theResult = theXalanTransformer.transform("/tmp/foo.xml",
          "/tmp/foo.xsl", "/tmp/foo.out");
    if(theResult != 0) {
        cerr << "UseStylesheetParam Error: \n" <<
theXalanTransformer.getLastError() << endl << endl;
    }

    XalanTransformer::terminate();
    XMLPlatformUtils::Terminate();
    XalanTransformer::ICUCleanUp();
}

The apache process will segfault on transform().
