How to only show text?

Question

I have a document for a student research project and want to know how many pages content without figures, listings and tables i have.
My university does differentiate between content and figures,... and we are supposed to write a specific number of content pages.

Therefor i woud like to deaktivate/disable/don't show/... any figure, listing and table.

Is this somehow possible?

EDIT: (I have a finished document. If i have to apply something to every figure, table and listing than it's more work than just making a copy and deleting everything.) But if you have a solution that works without compromise but with consideration from the start, then pls still feel free to share, even it doesn't help my problem.

Here's a LuaLaTeX-based solution. It defines a Lua function called hide_stuff which "gobbles" the contents of all figure, table, and lstlisting environments. The only input-related requirements are: (a) the environments' begin and end statements must not occur on one and the same input line, and (b) there's only one begin{...} or end{...} statement per input line.
Note that it's not necessary to modify or "prime" any of the existing figure, table, and lstlisting environments. All you need to do (besides using LuaLaTeX to compile the document) is to copy the code block from usepackage{luacode} to AtBeginDocument{...} into the preamble of your LaTeX document.

% !TEX TS-program = lualatex
documentclass{article}
usepackage{listings} % for 'lstlistings' environment    
usepackage{luacode} % for 'luacode' environment
begin{luacode}

in_group = false  -- initialize a Boolean variable
function hide_stuff ( buff )
  if string.find ( buff, "begin{figure}" ) or 
     string.find ( buff, "begin{table}" ) or
     string.find ( buff, "begin{lstlisting}" ) then 
            -- start gobbling
            buff = buff:gsub ( "begin%b{}.-$" , "" )
            in_group = true
  elseif string.find ( buff, "end{figure}" ) or 
         string.find ( buff, "end{table}" ) or
         string.find ( buff, "end{lstlisting}" ) then
            buff = buff:gsub ( "^.-end%b{}" , "" )
            in_group = false -- end gobbling
  elseif in_group == true then  
            buff = "" -- keep gobbling
  end
  return buff
end

end{luacode}  
%% Assign the fuction to LuaTeX's "process_input_buffer" callback
AtBeginDocument{directlua{luatexbase.add_to_callback (
   "process_input_buffer", hide_stuff, "hide_stuff" )}}

begin{document}

aaabegin{figure}
caption{AAA} end{figure}

bbb

begin{table} caption{BBB}
end{table}ccc

begin{lstlisting}
CCC
end{lstlisting}

uuubegin{figure} % empty "figure" environment
end{figure}vvv

end{document}

This can be solved by using booleans.

You define a boolean variable which states whether you want to include figures and tables or not. Each figure and table statement has to be surrounded by an if statement testing for the boolean variable.

The simplest way to do this is:

documentclass{article}
usepackage{graphicx}

newififplotfig  % you can also call it ifplottab or ifplotfigtab
plotfigtrue      % uncomment for 'setting' it to false

begin{document}
  Some text with reference to Fig.~ref{fig:myLabel}

begin{figure}[h]
    centering
    ifplotfig
      includegraphics[width=0.65textwidth]{./SOMEFIGURE.pdf}
    fi
    caption{Test Caption}label{fig:myLabel}
  end{figure}

Some more text with reference to Table~ref{tab:myLabel}...

begin{table}
    caption{Tables Caption}label{tab:myLabel}
    centering
    ifplotfig
      begin{tabular}{c|c c}
        Grid & Some Value & Another Value   hline
        CD24 & -1398 & -1191 
        CD72 & -1926 & -2655
      end{tabular}
    fi
  end{table}
end{document}

This solution comes from this and this answers. Here you will find an alternative solution.

In order to reduce the time spend on adding the if clauses you search & replace

begin{tabular} by ifplotfig begin{tabular},
end{tabular} by end{tabular} fi and 
includegraphics{...} by ifplotfig includegraphics{...} fi.

For the latter replacement you need regular expressions or a search & replace functions that uses non-regex wildcards. If you have no experience with these, you replace

includegraphics with ifplotfig includegraphics and 
.pdf} with .pdf} fi. The pdf needs to be replaced by the appropriate file ending of your figure files.

You can use e.g. environ to collect the body and throw them away:

documentclass[]{article}
usepackage{environ,listings}

RenewEnviron{table}{}
RenewEnviron{lstlisting}{}
RenewEnviron{figure}{}
begin{document}
abllbl

begin{figure}
figure
end{figure}

begin{table}
table
end{table}

begin{lstlisting}
abc
end{lstlisting}

end{document}

If you don't want to throw away the whole content, you can redefine the commands you want to ignore, e.g. renewcommandincludegraphics[2][]{}.
