Where can I find com.sun.xml.tree?

Question

Recently I was using java to achieve the transformation process from XML document to HTML document. The XML processor is Xalan-J. Of course, I also used Java API for XML(JAXP). During the process, I would use XMLDocument object, which need the help of com.sun.xml.tree, but I cannot find this package.
Could you please tell me where I can find it?
SDK's version:1.4.1
Xalan-J's version:2.5
JAXP's version:1.2

To DevMentee: Thanks for your codes.
I also coded pieces of programme to achieve my goal avoiding that package:
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
public class SimpleTransform
public static void main(String[] args)
throws TransformerException, TransformerConfigurationException,
FileNotFoundException, IOException
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new StreamSource("transform.xsl"));
transformer.transform(new StreamSource("myfile.xml"), new StreamResult(new FileOutputStream("myfile.html")));
System.out.println("*** The result is myfile.html ***");
