Catch output stream of xsl result-document

Question

I need a way to interfere in writting xsl result documents to avoid writting them to file system. Right now my template is writting to a temporary directory, and then i zip

You need to implement interface net.sf.saxon.OutputURIResolver
http://www.saxonica.com/documentation/javadoc/net/sf/saxon/lib/OutputURIResolver.html
You can redirect output in resolve method however you like. In my case this is how implemented class looks like.

public class ZipOutputURIReslover implements OutputURIResolver{

    private ZipOutputStream zipOut;

    public ZipOutputURIReslover(ZipOutputStream zipOut) {
        super();
        this.zipOut = zipOut;
    }

    public void close(Result arg0) throws TransformerException {
        try {
            zipOut.closeEntry();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public Result resolve(String href, String base) throws TransformerException {
        try {
            zipOut.putNextEntry(new ZipEntry(href));
        } catch (IOException e) {
            e.printStackTrace();
        }
        return new StreamResult(zipOut);
    }
}

After this you need to register net.sf.saxon.OutputURIResolver to trasnformer factory.

ZipOutputStream zipOut = new ZipOutputStream(new FileOutputStream("file.zip"));
factory.setAttribute("http://saxon.sf.net/feature/outputURIResolver", new ZipOutputURIReslover(zipOut));

When you load your template and run transformation all xsl:result-documents will be written directly to zipOutputStream.
