.xml file is a Snap! project file, so it'll only work in Snap! derivatives.
However, you can always export your project as an
.obj file and import it into your favorite modelling software. To do so, navigate to the project menu () and select
Download 3D model as... →
What you'd be exporting is the resulting model though. The program itself is not translatable into other languages, and it'd be very hard (if not nearly impossible) to do so, as other algorithmic 3D modelling environments work in completely different ways and use totally different metaphors. I do not know of any other environment where you control a shape-generator object in first person with turtle-geometry instructions and in real time.
Note that you can also export your 2D drawings as SVG files.
Hope it helped!
