            </script>

I would suggest getting a local copy of geoxml3.js, Zipfile.complete.js and ProjectedOverlay.js, rather than linking to the tip of the SVN tree. Those versions may change at any time.

Tried to use this code and this only highlights the poly from the first KML file when using multiple kml files ... any suggestion?

Note
Rectangle 27 0

javascript Change the KmlLayer colour in the Google Maps?

                    document.getElementById("sidebar").innerHTML = sidebarHtml;         //show to all link

            </script>

I would suggest getting a local copy of geoxml3.js, Zipfile.complete.js and ProjectedOverlay.js, rather than linking to the tip of the SVN tree. Those versions may change at any time.

Tried to use this code and this only highlights the poly from the first KML file when using multiple kml files ... any suggestion?
