Update passed in XML doc with pl/sql xmldom

Question

Hi,
I have an xml document that is passed in through a stored procedure as CLOB. I'm trying to use the XMLParser and XMLDOM to add an additional node
The XML looks something like the following
<rowset>
<row>
<firstname>john</firstname>
</row>
<row>
<firstname>jane</firstname>
</row>
</rowset>
I need to loop through each of <mynames> nodes and then add another node <lastame> so it looks like the following
<rowset>
<row>
<firstname>john</firstname>
<lastame>smith</lastame>
</row>
<row>
<firstname>jane</firstname>
<lastame>smith</lastame>
</row>
</rowset>
I have the following code
parseClob XMLPARSER.Parser;
newNames XMLDOM.DOMDocument;
tempNode XMLDOM.DOMNode;
mye xmldom.domelement;
     item_text xmldom.DOMText;
numofrows number;
     nodeList xmldom.DOMNodeList;
     newnode xmldom.domnode;
parseClob := xmlparser.newParser;
XMLPARSER.parseClob(parseClob,names);
newNames := XMLPARSER.getDocument(parseClob);
XMLPARSER.freeParser(parseClob);
nodeList := xslprocessor.selectNodes(xmldom.makeNode(newNames), '//rowset/row');
numOfRows := xmldom.getlength(nodeList)-1;
for i in 0..numOfRows LOOP
newnode := xmldom.item(nodeList, i);
          --create the new node
mye := xmldom.createElement(newName, 'lastname');
--add it to the new node   
tempNode := xmldom.appendChild(newnode, xmldom.makeNode(mye));
--update the text in the lastname   
item_text := xmldom.createTextNode(newNames, 'smith');
tempNode := xmldom.appendChild(tempNode, xmldom.makeNode(item_text));
end loop;
what happens is that when i write out the newnode xml out to a buffer i see the <lastname> tag
but when i write out the newNames xml out to a buffer after the loop is finished the <lastname> tag is
missing. like it didn't update the newNames xml
I've seen lots of example on how to create an XML document with the DOM from scratch but nothing about updating
an passed in xml document. any help would be appreciated

Updatexml is reference in Oracle 9i, I'm sorry i should have mentioned that I am using oracle 8i. Is there something you can use in oracle 8i?
