To Learn RegEx

Hello,

I will be working with text from files and manipulated them. Thus, I need to learn about RegEx. I know the HELP in visual studio has it and it even has examples, but those examples are not explained....all I see is a bunch of symbols that work together to get their results....They do not explain them

So, if anyone knows where I can go for better explanation of regex, that would be great.

I am working on c# visual studio 2003 .net
