Math & Science ⇒ Extract math expressions

[rbolliger]

Hello,

I am writing my PhD thesis and I have lot of equations in my text. In order to check that I used the right syntax everywhere, I would like to compile a document that only contains mathematical expressions. In particular all:

• $xxx$
• \begin{eqauation}xxx\end{equation}
• eqnarray
• IEEEqnarray
• ...

My question is: Is there any package or technique to perform such job?

Thank you for the reply

Raffaele
