SAX startElement() namespaceURI is null

           Summary: SAX startElement() namespaceURI is null
           Product: XalanJ2
           Version: 2.5Dx
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.transformer
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: jmercay@scdi.org


When using a SAXResult in a Transformer.transform(), the first startElement()
event (representing the root node) contains a null namespaceURI. From the SAX
spec., it must be the empty string instead of null. 

I can reproduce this on the Xalan bundled with JDK 1.4.1 and Xalan 2.5D1.
Below is a simple example:

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

import javax.xml.transform.sax.SAXResult;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.stream.StreamSource;
import java.io.File;

public class SAXTest {

    public static void main(String[] args) throws Exception {

        Transformer trans = TransformerFactory.newInstance().newTransformer(new
StreamSource(new File("stylesheet.xsl")));
        trans.transform(new StreamSource(new File("input.xml")), new
SAXResult(new DefaultHandler() {
            public void startElement(String uri, String localName,
                                     String qName, Attributes attributes)
                    throws SAXException {
                System.out.println("uri="+uri+" name="+localName);
                super.startElement(uri, localName, qName, attributes);
            }
        }));
    }
}


stylesheet.xsl:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
        <xsl:copy-of select="/root/*"/>
    </xsl:template>
</xsl:stylesheet>


input.xml:
<root>
    <note>
        <to>Tove</to>
        <from>Jani1</from>
        <heading>Reminder</heading>
        <body>Don't forget me this weekend!</body>
    </note>
</root>

Result:
uri=null name=note
uri= name=to
uri= name=from
uri= name=heading
uri= name=body
