[jdom-interest] Transformation differences when using a JDOMResult vs. a DOMResul t

[Sexton Michael]

Hi, 

I have a need to transform an XML document into an XSL document, in
preparation for a final transformation on an XML document.

I have written a test class that transforms a file (empty.xml) using another
file (test.xsl).  The Document returned is different, and incorrect, if I
use a JDOMResult instead of a DOMResult.

Using DOMResult returns: 
<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<foo:myelement xmlns:foo="http://www.mywebsite.org">content blah
blah</foo:myelement> 

Using JDOMResult returns: 
<?xml version="1.0" encoding="UTF-8"?> 
<foo:myelement xmlns:foo="http://www.mywebsite.org"
foo="http://www.mywebsite.org">content blah blah</foo:myelement> 

Notice the extra attribute returned using the JDOMResult
(foo="http://www.mywebsite.org"). 

Is there a way to make the JDOMResult not have the extra attribute? 

Thanks in advance,

Michael

Example info below

I am using jdk 1.3.1, xerces 1.3, xalan 2.1.0, and I have downloaded the
latest code from cvs.jdom.org this morning. 

Here is my empty.xml file: 
======================================================================== 
<!-- edited with XML Spy v3.5 NT (http://www.xmlspy.com) by Maggie (OGI) -->

<root>empty</root> 
======================================================================== 

Here is my test.xsl file: 
======================================================================== 
<?xml version="1.0"?> 
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

                        xmlns:foo="http://www.mywebsite.org"> 
        <xsl:template match="/"> 
                <foo:myelement>content blah blah</foo:myelement> 
        </xsl:template> 
</xsl:stylesheet> 
======================================================================== 

Here is my test program:
