Parsing does not support namespace #105

Hello,

I think there is a problem when using a kml file using namespace like the 
attached example.
After searching a bit, I guess I found the problem in this piece of code :

if (!!GeometryNodes && (GeometryNodes.length > 0)) {
          for (var gn=0;gn<GeometryNodes.length;gn++) {
             if (!GeometryNodes[gn].parentNode ||
                 !GeometryNodes[gn].parentNode.nodeName) {

             } else { // parentNode.nodeName exists
               var GeometryPN = GeometryNodes[gn].parentNode;
               Geometry = GeometryPN.nodeName;

        // Extract the coordinates
        // What sort of placemark?
        switch(Geometry) {
          case "Point":
...
}

When kml document uses namespaces, the nodeName is not "Point", but 
"namespace:Point".
Instead of using the nodeName, the localName attribute whould fix the problem.

This problem prevent usage of namespaces which are regular though.

Why do you need to do that?

Hello,

We produce kml data using the java API 
http://labs.micromata.de/projects/jak.html, that produces by default xml with 
namespace.
Presence of namespace in the kml causes the parsing to fail because of the 
Geometry = GeometryPN.nodeName; that get the nodeName including namespace, 
causing the switch to use the "default" block.
As the rest of geoxml3 code supports namespace, it seems simple to me fo fix
Geometry = GeometryPN.nodeName
by changing it to Geometry = GeometryPN.localName;

I tested it and it seems ok to me.
Is it ok for you ?

Is there a chance you would consider fixing this issue, or do you think it's 
worthless ?
Thanks.

I would consider a patch that does that, if you would like to provide one, as 
long as it is backwards compatible (doesn't break existing functionality).

Hello,

Here is the requested patch. Please note that as I haven't got any unit tests, 
I can't check it, though it works for me.
Thank you.
