How feasible to extract data from KML/KMZ files


We have a large bunch of KML files, they are basically global cable maps. In our company they are wide-spread and everybody uses them with Google Earth.


Now there is an interest to extract information from these files, e.g. Cable Lengths. With Google Earth extracting Cable Length is a very tedious task because you need to look at each tiny segment's height profile. So I started writing a software to read those files, problem is: the quality of most of those KML/KMZs is really low. Sometimes linestrings contain too many or even duplicate coordinate-sequences. You can even see that in Google Earth.


So question: does it make sense to try to parse these KMLs to calculate cables' total length? Or is this too much asked from KML format?
