Load the SVG file as a text file and parse the XML there to get the path, hence the coordinates you want. More or less (there can be transformations...).

Yeah, that direction seems to be satisfying.
But what meens "to parse the XML"?
I tried to Open the svg in different IDEs (Text Editor, notepad++), what looks always to difficult to parse it.

I will try to find a SVG XML EDITOR, it seems to be quite simple constructed, shouldnt there be a code which I could use to translate my svgs to formated text? If not I should write it or could be already implemented in geomerative, but I have no clue where to look.

thanks

EDIT: I found the translater in Geomerative, but its too complex for me to get it. Logicaly thought an Tool to translate from SVG/XML to Processing text (JAVA) should exist, so I can just copy/paste my shapes like:

beginShape();
....
endShape();

I didn't write that parsing SVG would be simple...

Actually, looking at PShape's reference (well, the source, actually), I found a getVertex(n) method that returns an array of floats. n is between 0 and getVertexCount(). You can also use getVertexX(n), getVertexY(n) and even getVertexZ(n) if you do 3D (not in SVG...).
