Hi,

I like to edit pdf architectural plans with Inkscape, sometimes I use it as workaround to dwg/dxf conversion issues and usually these pdf have many empty groups in the object list, is there any way to select all these empty groups?

thanks

I'd try a text editor.

Find and replace: <g></g>

(Replace with nothing.)

Thanks.

I've found a graphical way to achieve it:
. box select the entire drawing > in this way the empty groups are not selected;

. menu edit, invert selection > this selects all the empty groups;

. delete.

Gcodetools made a couple of thousand empty groups for me, which I wanted to delete. Selecting the empty groups in the layer tree made the whole program bog down way too long for my patience..  box selecting everything, and invert selection/delete made it in seconds :)
Thank you!
