The '''scripted SVG parser''' basically just maps the SVG xml structure to the property tree by adding corresponding Canvas elements as child nodes.

There's a tiny Nasal module named svg.nas (see $FG_ROOT/Nasal/Canvas) that will read those SVG/XML files and convert them into Canvas nodes (OpenVG/ShivaVG paths) - in other words, depending on the nature of the differences in the output, it should be possible to patch up the svg parser to also support the new format. | |||
To make changes to that module, you need to understand how parsing works and how a stack works (the data structure). | |||
