How to extract a tags content using DOMParser in PL/SQL

Question

The structure of my xml-document is as below:
<Reply>
<Errors>
<Error Number="0">No Error Occured</Error>
</Errors>
</Reply>
Using DOMParser in PL/SQL iam able to extract the value associated with the 'Number' attribute in the <Error> tag, but i am unable to extract the text (error message => "No Error Occured") embedded in the <Error> tag.
How should i go about? Provide any hints, if possible sample code.
Thanks in Advance.

In order to get the text, you need to check the child node, as the text really lives by itself.
For example I modified the DOMSAMPLE to dislay the text not just the attributes. I have included the code below.
I hope that this helps you.
for i in 0..len-1 loop
n := xmldom.item(nl, i);
dbms_output.put(xmldom.getNodeName(n) || ' ');
n := xmldom.getfirstchild(n);
IF xmldom.getnodetype(n) = xmldom.Text_Node THEN
v_val := xmldom.getnodevalue(n);
dbms_output.put_line(v_val);
END IF;
end loop;
I really think that the XML tools in Oracle would be much more useful, is they were accompanied by complete documentation.
