Regular Expression Testing

 

 
    In this document, there is a lot of text that can be matched  
    using regex. The benefit of using a regular expression is much 
    more flexible — albeit complex — syntax for text 
    pattern matching. 

 

 
    After you get the hang of regular expressions, also called  
    regexes, they will become a powerful tool for pattern matching.
