(but everyone in Google Maps. Yes. I opened with gedit, a text-editor and
find that they had different structure. The one that was able to open,,
separate the xyz with comma/space separation:

17.585642,59.8386,31.0 17.585693,59.838562,31.3 17.585735,59.838512,36.4

17.58585,59.838303,35.3 17.585823,59.838257,....

and the ones I could not open have this:
...<gx:coord>17.673456 59.870106 16.6</gx:coord><gx:coord>17.673555
59.87012 16.9</gx:coord><gx:coord>17.673653 59.870136
16.6</gx:coord><gx:coord>17.67375 59.870148

17.2</gx:coord><gx:coord>17.673935 59.870182 18.7<....

I will ask the developer about this..If he have change, or If i have
exported in different ways.

I'm totally new to use SQL/relations databases with ArcGIS and QGIS, and
are just now trie to learning. I assume that sqlite lack

the sqlite seems to lack spatial data, even if there are coordinates. Will
try to learn more about this...

Another thing was that the kml-files that opened was not placed right with
my background map (RT90 2,5 gon V (metric coordinate system) despite I
checked 'on the fly reprojection' and I thougt all kml was in WGS 84 by
default.
