Saxon

Hi all,

I´m trying to pre-load a xml doc in Saxon´s cache in order to use it inside my xslt with a document() function.

This is my Java code:

Source xsltTarget = new StreamSource(xsltInput);
String path = "C:/xml";
try {
	TransformerFactory tFactory = TransformerFactory.newInstance();
	tFactory.setURIResolver(new MyResolver(path));
	Transformer transformer = tFactory.newTransformer(xsltTarget);
	Controller controller = (net.sf.saxon.Controller) transformer;
	Configuration configuration = controller.getConfiguration();
        configuration.setConfigurationProperty(FeatureKeys.PRE_EVALUATE_DOC_FUNCTION, Boolean.TRUE);

        Source source = transformer.getURIResolver().resolve("document.xml", "");
        DocumentInfo newdoc = configuration.buildDocument(source);
	configuration.getGlobalDocumentPool().add(newdoc, "document.xml");

        Source streamSource = null;
        StreamResult resultTarget = null;

	streamSource = new StreamSource(new StringReader(xml));
	resultTarget = new StreamResult(new StringWriter());
	transformer.transform(streamSource, resultTarget);

....

and my implemented URIResolver is:

    public static class MyResolver implements URIResolver {
	String base_path;

	public MyResolver(String base) {
	    this.base_path = base;
	}

	@Override
	public Source resolve(String href, String base) {
	    StringBuffer path = new StringBuffer(this.base_path);
	    if (!base_path.endsWith("/") && !base_path.endsWith("\\")) {
		path.append(File.separator);
	    }

	    path.append(href);
	    File file = new File(path.toString());
	    if (file.exists()) {
		System.out.println("Resolved!!");
		return new StreamSource(file);
	    }

	    return null;
	}

    }

Then, in my xslt, I want to define my doc variable to be accesed by xpath expressions:

...

I wanted to know if this is a correct mode to pre-cache a xml file. With that code I don´t see any performance gain between pre-caching and without pre-caching.

Am I doing right? Is there any useless code? Do I have to add anything?

Thank you in advance.

Regards.
