Several handy programs exist like MacGPX and WinGDB3 which can convert KML and KMZ files to GPX files.
However, some KML or KMZ files don't contain (or just a few) placemarks and/or paths, while Google Earth shows them (all). In that case the file contains "Network Links". Network links are references to other KML/KMZ files, usually on the internet. MacGPX and WinGDB3 cannot handle these references, so placemarks and paths in those referenced files are not converted.
With GetKML you can combine this kind of files to a single GPX file, which in turn you can open with MacGPX or WinGDB3 for further processing.
GetKML only processes placemarks (turning them into waypoints) and paths (tracks). Polygons and other objects are not supported. Secondly the application can process network links pointing to the internet only, not references to locally stored files.
GetKML can process KML and KMZ files and even links to files on the internet, for instance those in Google Maps ("Show in Google Earth"). Open a file, type in an URL in, or drag a file or URL onto the window. Click "Convert". GetKML asks you where you want to put the GPX file and the program starts to collect the files.
When you have a slow internet connection or in case of a large amount of data it will take a while. GetKML shows which files or URLs are processed.
