You probably want to intercept the post or edit action in your config.php,
something along the lines of

    if ($action=='edit' && preg_match('/some regexp/',$pagename) {
      ...
    }

I probably need a slightly more detailed example of what you want
to happen before I can give better pointers beyond this.

The code

   $page = ReadPage('X.Y');

reads the contents of X.Y into the array $page.  $page['text'] then
contains the page's current text.  Note that as a side effect ReadPage() 
also does Lock(1), which prevents any other PmWiki process from writing 
a page until the current script has exited or executed Lock(0).
