 Hi and welcome back to the next module or you can say the last module of this course. My name is Krishan Rajarana. In the previous module, we studied the regular expressions, basic elements and syntax in detail and demonstrated how you might assemble and test a regular expression pattern. So by now you know that a regular expression is nothing more than a way to describe something represented in a string of text. Now in this module, we will see some real time use cases of regex and we will see those regex syntaxes which we have learned in action. So in this module, we will cover the following use cases of regex. First we will create regex to match US zip code and then we will create regex to match SSN number and then we will create regex for credit card number and then we will create regex for matching date and then we will create regex to match a website URL and then for finding home address, we will create again another regex and then at last we will create regex to matching email address. Now to perform all these demos, we will be using online regex testing tool and PDF multi-tool provided by ByteScout. Now regarding this PDF multi-tool, we have already learned about this tool in module 1, so you can refer the previous module video. Alright, so now let's get started.
