I second @Alan-Kilborn 's remarks, IMO you should no longer be considered a beginner. After the amount of questions you posted related to regular expressions and the answers you got based on goodwill of other community member(s) (i.e. @guy038), you’ve had plenty of time to learn the basics.
There are lots of sites available for regular expression related questions specifically, to name some:
Learn regular expressions the hard way Regular Expressions 101 Regular-Expressions.info (by RegexBuddy author/developer).Furthermore, one doesn’t have to be a programmer to learn and use regular expressions.
