XNA curve import from Maya?

I am trying to import a movement curve from Maya into my XNA game, but I cannot figure out how. Basically I want to catch the curve by it's name, and look up its values at different points of time.

Are curves exported 开发者_运维百科into FBX at all? And, if not, then how to catch it?

Edit: Maya can export to Maya ASCII, and I tried to parse it, but I am not sure what formula I should use to recreate the curve.

Here is a Maya ASCII segment defining a typical curve:

createNode transform -name "curve1";
createNode nurbsCurve -name "curveShape1" -parent "curve1";
    setAttr -keyable off ".visibility";
    setAttr ".cached" -type "nurbsCurve"

        ;

I managed to find the file format reference somewhere, the important info here is the knot indexes (16 0 0 0 1 2 3 4 5 6 7 8 9 10 11 11 11) and the coordinates (all lines containing three numbers).

But, I still have no idea how to recreate the curve. I googled a lot for nurbscurves, bsplines etc, but could not successfully match the result in Maya with any code I could find.

I've achieved this in 3dsmax by exporting the curve in Ascii format and parsing the text manually, does Maya have any such exporter?
