Ivory Tower
We learned in the last episode that "Regular Expressions" or "RegEx" is just another way of saying, "find a pattern"
We learned that we can use RegEx to search a string for that pattern according to a set of parameters and modifiers that WE determine
The usage of RegEx is as Follows:
$nameofstring =~ (Match Operator) / (expression) / (expression) / (Match Expression Operator)
$nameofstring =~ (action to take)/(pattern to match)/(pattern to replace match with)/(how to search)
m/ Match Regular Expression s/ Substitite Regular Expression tr/ Tranliterate Regular expression Useful Match Operator Modifiers
g Match globally, find ALL occurences i case insensitive m treat string as multiple lines o Evaluate the expression only once s treat string as single line x Use extended regular expressions (Allows you to use white space in the expression) Hosts: Fr. Robert Ballecer, SJ and Shannon Morse
