XSLT Compiler for C/C++?

[unclejemima]

Does anyone know of an existing XSLT Compiler for C or C++, such that it takes as input an XSL stylesheet and outputs some form of executable code, binary, compiled C code, assembly, shared library, etc. which can then be directly executed to convert XML files?

http://sourceforge.net/projects/xsltc/

is a proof-of-concept implementation that has been dead since the year 2000.
I realize there are java, HTML compilers out there that perform the task, but I am under a C/C++ constraint with a speed/efficiency priority, worst case would be using an interpreter or doing inter process communication with a fast java compiler like Gregor/XSLT.

Anyone got any tips or ideas?

Have you actually downloaded and built the xsltc project? After a quick look at the code, it seems pretty clean, and might be faster to fix (see the known bugs list) and optimize than to find something newer/more mature. I admit, I did not look at it closely enough to determine how complete it is.

Don't invest too much time in this before you test the hypothesis that this will create any additional speed or efficiency.

Especially if you can find a C/C++ library that will convert an XML file and an XSL file into another file of your choice of type in this many calls:

            DocumentBuilder builder = factory.newDocumentBuilder();
            document = builder.parse(datafile);

            // Use a Transformer for output
            TransformerFactory tFactory = TransformerFactory.newInstance();
            StreamSource stylesource = new StreamSource(stylesheet);
            Transformer transformer = tFactory.newTransformer(stylesource);

            DOMSource source = new DOMSource(document);
            StreamResult result = new StreamResult(outfile);
            transformer.transform(source, result);

(This is the brains of a nice little Java proggie called Stylizer from the Sun site. You can google for it with the search string "stylizer.java".)

See Xalan

http://xml.apache.org/xalan-c/

especially compiled stylesheets.

XalanCompiledStylesheet* compiledStylesheet = 0;
compiledStylesheet = theXalanTransformer.compileStylesheet("foo.xsl");
assert(compiledStylesheet!=0);
theXalanTransformer.transform("foo1.xml", *compiledStylesheet, "foo1.out.");
theXalanTransformer.transform("foo2.xml", *compiledStylesheet, "foo2.out");
...

Most likely, Xalan is a heavy-weight solution but it's stabe and fast one.
