I want to apply a transparent texture to an emssion node in a way that the the emission node will emit just from the not transparent parts of the image texture. How to achieve this effect ?

Here' s a Picture of it enter image description here

    $\begingroup$ Use the alpha as the factor for a mix shader of Transparent and Emision $\endgroup$ – someonewithpc Sep 15 '14 at 11:21

Are you going for something like this?

Glow with transparency

If so, then it's as simple as someonewithpc said, just an Emission shader mixed with a Transparent shader using the texture for the Fac.
