Node location in an XML file with DOM?

Hi there,

hopefully a short question for an expert: how can I determine the location
of a DOM-Node (or a DOM-Element) in a document previously parsed from a
file?

My problem is, that I want to load some XML encoded configuration data from
a file to the memory and process it there by stepping through the DOM-tree.
Since the configuration data might be edited manually, there might be
logical errors in it even if it is well formed. I intend to report logical
errors in the manner 

... missing Tag <Row> below element <Grid> at line 12

I know that XML schema is a solution for such things, but I intend to have
my own program logic and logging facilities for this. In Java 5.0 I found an
Interface DOMLocator but don't know how to obtain an Object of this
interface from a living DOM-document. 

Are there any suggestions or hints?

with kind regards
Bernd
