how can i convert a color from hex code (#ff00ff) to RGB vector?

split the hex into three parts, two characters each

ie. #FF00FF is
R - FF
G - 00
B - FF

then convert those parts to decimal

R - 255
G - 0
B - 255

you can use the calculator under Windows, switch to scientific mode in the menu:

Start > Run > calc

hmm.. why blender exporter is creating RGB colours with values <1 ?

colour
Sets the RGB reflectance (albedo). All components should be in the range [0, 1)
Each component will be silently clamped to the range (after reverse gamma correction) [0, 0.9].
As of 0.7 test2, the RGB colour will be 'reverse gamma corrected' – all components will be
converted to display values by raising to the power of 2.2.
type: real 3-vector
restrictions: Each component should be in the range [0, 1)
units: dimensionless

From manual....

Then divide the result by 256 !

exactly
very simple

If you maximum result is 255, but it SHALL be 1, just divide by 256 (the +1, 'cause of 0 also is a value)
