Salam for all,
For example :
Input SVG : One layer (root) with n groups
Output SVG : n layer (each layer contains one group

There is a simple way to do it with python ? python/xml ?

Thanks and best regards

Layers are (technically) groups in Inkscape.

You just need to add inkscape:groupmode="layer" attribute to each group <g> node.

Any language that can open an xml file and process it should be able to handle the task (outside of inkscape).

Beware of nested groups. You should only add the above to the outer-most groups. I don't know what Inkscape would do if it thought an inner group was a layer.

No problem. Inkscape supports sublayers (right from the layer dialog, insert a new layer before, after or as a sub-layer)

Gee, you learn something new every day. Thanks.

Thanks ! Happy to find a solution easier than I expected.
From your answer, I modify (with text editor) :

To :

How to use the <i> attribute ?

Sorry - the <i> and </i> came because I posted from elsewhere and it didn't get converted to bbcode.

What you show is exactly what you need - you don;t even need the label line.

Here is one I did with search/replace in a text editor, each group in the original layer ended up as a sublayer of the original "Layer 1":

Great , It's so easy to do.
I summarize (case of an SVG file that has one layer) :
1- Create groups
2- In a text editor, remove :

and the last

3- replace all :

with :


See the two attached captures.
Thanks !
