3DXML Files?

Okay, I’ve looked around, asked in places and haven’t received a single answer or anything that works so far.

Basically I’ve been trying to get models through 3DVia printscreen. Other than flipped normals, the models rip just fine. The only problem is, the format. 3DXML doesn’t seem to be supported by any other program. And any scrips I find are either outdated, do nothing, don’t show up even when installed or just give errors.

Basically has anyone got a WORKING script or plugin for importing 3Dxml files into either 3DSmax2010 or Blender 2.49b?
