Moving points from the height text in rhino

Hello!

I've got a file with the terrain elevations (quite complex) in 2D: in rhino they are a point with a text (with the quote) nearby.

In order to generate the 3d surface of the terrain I have to move all those points on the Z axis of the value that is written in the rhino text nearby. 

I was wondering if there is a way to do this in grasshopper in order not to move every (453!!) point one by one!

Thank you!

best!
