Using regular expressions is the way to go for these kind of problems, so you are on the right track already.
I suggest you take some time and introduce yourself into regular expressions, believe me it is a time well spent. There is an introduction by MathWorks here, but Im sure you will find many other useful introductions online (at quick glance, the MathWorks introduction is probably not suited for people who never worked with regular expressions before). When you are familiar with the basics have a look at 'capture groups', this is what you need when you want to extract information from a string.
I'd like to suggest that you use more family friendly examples next time. These might keep some people from answering your questions...
