Assign To: (was: Xalan Developers Mailing List)
type: Improvement (was: Bug)
Description:
import java.io.FileInputStream;
import javax.xml.transform.Templates;
import javax.xml.transform.sax.SAXTransformerFactory;
import javax.xml.transform.sax.TransformerHandler;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
import org.xml.sax.helpers.AttributesImpl;
public class Test {
public static void main(String[] args) {
try {
SAXTransformerFactory f = (SAXTransformerFactory)
SAXTransformerFactory.newInstance();
Templates t = f.newTemplates(new StreamSource(new
FileInputStream("in.xsl")));
TransformerHandler th = f.newTransformerHandler(t);
th.setResult(new StreamResult(System.out));
th.startDocument();
th.startElement("","foo","foo",new AttributesImpl());
th.endElement("","foo","foo");
th.endDocument();
th.startDocument();
th.startElement("","foo","foo",new AttributesImpl());
th.endElement("","foo","foo");
th.endDocument();
} catch(Exception e) {
e.printStackTrace();
}
}
}
If you run this code with any valid in.xsl file, the template is instantiated
only once.
It's true, that in JAXP-1.1 specification it is not explicitly stated that
TransformerHandlers should be reusable, but it is stated that Transformers
should be reusable, and my opinion is that it would be reasonable and natural
to be able to reuse TransformerHandlers as well.
