Make a Captions Page

I want to know if there is an easy way to extract the captions of one latex file with the numbers of the figures they are from. For example if I hav开发者_如何学编程e 3 figures in defined in my latex file, I need to create a document with the captions of those figures, e.g.,

Fig. 1. Caption of Fig. 1 
Fig. 2. Another caption
Fig. 3. Yet another caption

Is there any way of doing this using latex? or should I do it with other program? I have several figures, so I don't want to go and extract the captions one by one, because I have to number them manually.

Solution. I solve the problem with a work around. I use another file to include the list of figures and process them separately. The file that I included contains a modified list of figures as follows

{\renewcommand*\numberline[1]{Fig.\,#1:\space}
\makeatletter
\renewcommand*\l@figure[2]{\noindent#1\par}
\makeatother
\listoffigures}

Then, I include it in the original file with \include command. Then it creates the list of figures file as file.lof, I used that file to compile a minimal file to produce the list of figures separately.

\documentclass{article}
\usepackage{subfigure}       % This avoids problems with subfigures captions
\usepackage{amsmath,amssymb} % I used math in my captions
\nofiles                     % This makes the aux and lof file not to be deleted
\begin{document}
\include{list}               % Includes the same file as before
\end{document}

I was using a different class, other than article, therefore, I need to copy some redefinitions in the auxiliar file. Rename the file.lof to this new file, so latex find it and it will do the work. I put all this in a script and now it works automatically. Hth.

The \listoffigures control sequence may help you.
