Basically what I would like is a possibility to copy-paste the LaTeX code of a formula from a PDF document (that has been created with LaTeX), for using it in another LaTeX document. Is this possible?

I'm not aquainted enough with the pdf format to know if this is feasible, I was thinking along the lines of the Text underlay archived works use.

Edit: What I was thinking of was something similar to MathJax
