Don't know how to explain this ( getting data )

[cdlink14]

Ok firstly using this as an example... ( Posted by Paul186 here = >> Clicky <<

1.  HTTP.Download("http://www.ipchicken.com/", _TempFolder .. "\\tempfile", 2.  MODE_TEXT);
3.  error = Application.GetLastError();
4.  if (error == 0) then
5.      page = TextFile.ReadToString(_TempFolder .. "\\tempfile");
6.      File.Delete(_TempFolder .. "\\tempfile", false, false, true);
7.      ip = string.sub(page, string.find(page, '%d+%.%d+%.%d+%.%d+'));
8.      if (ip ~= nil) then
9.          Dialog.Message("IP Address","Your public IP address is '" .. ip .. "'.");
10.      else
11.          Dialog.Message("IP Address","Not found");
12.      end
13.  else
14.      Dialog.Message("Error", _tblErrorMessages[error], MB_OK, 
15.  MB_ICONEXCLAMATION);
16.  end

From what I can gather on line 7. The '%d+%' is used to find a set of numbers.

What would I do to find a set of letters?

If possible could someone show me by making an example using this test url

I hope this is possible.
Thanks for any help,

This is a regular expression, or a pattern, like it is called in Lua.
You find documentation here, but is not the most easy stuff to understand.

Ok I've managed to get the first bit of the code done, but now it's a case of how do I do the rest of the code?

( Bold code is part I've figured out so far )

Now what about the last part? The file/filename, since i'm effectively making a download manager. The files length could be anything, could contain a number of any characters, a wide selection of ".", etc
