Problem with getting the nodevalue

Question

Hi all,
I have the following xml-file:
<ROOT>
<ROW1>
<Outer> Outer1 <Inner>Inner</Inner> Outer2 </Outer>
</ROW1>
</ROOT>
I need to get the full-nodevalue of <Outer> (Outer1 <Inner>Inner</Inner> Outer2).
I do not use the XMLDB and XMLType.
I parse the XML-File using xmlparser and xmldom packages from pl/sql.
Any ideas?
Regards

set serveroutput on
declare
p xmlparser.Parser;
doc xmldom.DOMDocument;
procedure traverse( node in xmldom.DOMNode, nivo in integer )
is
nl xmldom.DOMNodeList;
begin
nl := xmldom.getChildNodes( node );
for j in 0 .. xmldom.getLength( nl ) - 1
loop
if xmldom.getnodetype( xmldom.item( nl, j ) ) = xmldom.text_node
then
dbms_output.put_line( rpad( '.', nivo * 3 ) || xmldom.getNodeValue( xmldom.item( nl, j ) ) );
else
dbms_output.put_line( rpad( '.', nivo * 3 ) || xmldom.getNodeName( xmldom.item( nl, j ) ) );
traverse( xmldom.item( nl, j ), nivo + 1 );
end if;
end loop;
end;
begin
p := xmlparser.newParser;
xmlparser.parsebuffer( p, '<ROOT><ROW1><Outer> Outer1 <Inner>Inner</Inner> Outer2 </Outer></ROW1></ROOT>' );
doc := xmlparser.getDocument( p );
xmlparser.freeParser( p );
traverse( xmldom.makeNode( doc ), 0 );
xmldom.freeDocument( doc );
end;
ROOT
. ROW1
. Outer
. Outer1
. Inner
. Inner
. Outer2
