Error if a child element has no children in function CreateMarker

Hi,

I have found a small error in file loadgpx.4.js
(http://okuda.ca/googlemaps/loadgpx.4.js).
The error occurs in Internet Explorer with test file lewis_clark.gpx
(http://www.travelbygps.com/guides/lewis_clark/lewis_clark.gpx).
In function CreateMarker empty nodes are ignored by testing for nodeType =
1 (elements only).
However, an elemement "link" may still have no children, such as in
lewis_clark.gpx:

In that case, firstChild is null and an error occurs (firstChild.nodeValue).

To capture this exception, an extra test is needed:

115     // Ignore empty nodes
116     if (children[i].nodeType != 1) continue;
117     if (children[i].firstChild == null) continue; // ";

bye,
