Automatic XML output generation

Question

i am trying to generate automatic xml output for a report. report dsnt take any parameters. i have written a xml definition
<report name="XML Report date spec GRFS03" DTDVersion="1.0">
<layout>
<section name="main">
<groupLeft name="G_LOC_CODE" >
<group>
<field name="LOC_CODE" source="loc_code"/>
<field name="QTTY" source="qty"/>
<field name="STK_NO" source="stk_no"/>
<field name="UNIT_COST" source="unit_cost"/>
<field name="USER_CODE" source="user_code"/>
</group>
</groupLeft>
</section>
</layout>
<customize>
<object name=”Gary D” type=”Report”>
//<properties>
//<property name=”beforeReportType”>File</property>
//<property name=”beforeReportValue”>C:\xmlreport.html
//</property>
</object>
</customize>
</report>
i have used SRW.APPLY_DEFINITION(xml_report.xml) for runtime customization but when i run report i get error : REP-6106: error in XML report definition at line 3 in 'xml_report.xml'
Root element name must match the DOCTYPE name.
can anyone suggest a solution to this?

JDOM has an XMLOutputter.
DOM Level 3 allegedly supports outputting from the DOM itself.
However if you don't want to use JDOM, and you don't have access to DOM Level 3, there is a way to do it using transformers. I'm not sure if this is a trick or whether it's considered the standard way to do it.
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
Document dom; // this is what you want outputted
OutputStream stream; // this is where you want it outputted
Transformer identity = TransformerFactory.newInstance().newTransformer();
identity.transform(new DOMSource(dom), new StreamResult(stream));Note that it's not actually much code if you keep the identity transform around for reuse. JDOM's approach is a lot simpler though. :-)
