Read Syntax?

[lmsmi1]

I have some code syntax like this:

IOSTREAM io;
io.print("Hello World!");
io.pause();

This is syntax a lot like C++, so I'm assuming it's something quite simple to do. How would I go about parsing this kind of syntax? All I need to do is get the text before the '.', after the '.' but before the '(', after the '(' but before the ')', and get the ';' (semicolon). And then I need to store it into a vector (string). Suggestions?
