Retrieve equation objects from plain text

[gerasimosRagkavanis]

Hello, I am new in VMA programming so I am facing a problem. I have received some huge files that contain a lot of equations but what happens is that there was the original one, then saved as pdf and then from pdf editor I received the word version. So as you can understand the equations now are plain text because when I highlight all the equation objects with VMA for a file i just created and inserted equations it works. My script highlights every equation but when I do it with one of the document I have received even though I can see some equations when I run the same script nothing is highlighted. I would really appreciate any help any if what I am trying to do is even possible.



Thanks in advance.
