On 7.April I asked here and on the wikipedia help-desk how to get such a list: link
I now downloaded the file "commonswiki-20150417-all-titles".
Then I get all entries that end with ".svg".
So far, so good.
First problem: But how can I automatically find out the path to the real svg-file and not just a preview site with a png or jpg file? The all-titles file only gives the file name, and not the path.
Example: Preview site: commons.wikimedia.org/wiki/Blason_ville_fr_Servigny-l%C3%A8s-Sainte-Barbe_57.svg
Real svg-file: upload.wikimedia.org/wikipedia/commons/c/c5/Blason_ville_fr_Servigny-l%C3%A8s-Ste-Barbe_57.svg
Second problem: Some files seem to need to be added a "File:" prefix to to find the preview site. For example: 11-cube_t0_B5.svg
But that "File:" is not needed for the real svg-file path.
How is this dump-file used?
In short: How to get the real path to the real svg-files?
