Hi, I am very new to MEL script.

I have a simple NURBS plane and I use this command to query the world CV positions:

getAttr surfaceInfo.controlPoints["*"];

The results I got is
X1 Y1 Z1 X2 Y2 Z2 X3 Y3 Z3 ...

I need to print it out in this format:
X1 Y1 Z1
X2 Y2 Z2
X3 Y3 Z3

May I know how should I approach this?
Hope you guys can help me. Thanks!

$cvs = `getAttr surfaceInfo.controlPoints["*"]`;
for(int $i=0;$i<size($cvs);$i+=3)
{
print ($cvs[$i] + " " +$cvs[$i+1] + " " +$cvs[$i+2] + "\n");
}
