Serializing XML Documents(not Java Serialization)

Question

Hi,
Iam looking for a class that can serialize the XML documents.
Heres the problem in detail:
- I need to create an XML String from scratch taking data from a database.
- I created the XML Document adding the childs and attributes.
- I need an XML string from the document. Iam not exactly sure how to do this. But Apache Xerces package provides an XMLSerializer class where we can convert the document into a string.
Is there any functionality provided. If so where can i find it.
Thanks,
-Rao

Not sure if this is a bug or not (filing one just in case it is) but the following program demonstrates that with 2.0.2.9 the internal subset is serialized correctly if the document was parsed with validationMode set to true. If set to false only the entities show up in the internal subset.
package xmlbugs;
import java.io.*;
import org.w3c.dom.*;
import oracle.xml.parser.v2.*;
public class TestSerializeLocalSubset {
private static final String xml =
"<?xml version='1.0' encoding='UTF-8'?>"+
"<!DOCTYPE bar ["+
"<!ENTITY bar 'baz'>"+
"<!ELEMENT foo EMPTY >"+
"<!ELEMENT bar (foo) >"+
"]>"+
"<bar><foo/></bar>";
public static void main(String[] a_ ) throws Exception {
System.out.println("Test with parser in validation mode = false");
DOMParser d = new DOMParser();
d.setPreserveWhitespace(false);
d.setValidationMode(false);
d.parse( new StringReader(xml));
Document x = d.getDocument();
XMLDocument xx = (XMLDocument) x;
xx.print(System.out);
System.out.println("Test with parser in validation mode = true");
DOMParser d2 = new DOMParser();
d2.setPreserveWhitespace(false);
d2.setValidationMode(true);
d2.parse( new StringReader(xml));
x = d2.getDocument();
xx = (XMLDocument) x;
xx.print(System.out);
}
