RUBY - REGEX
Say for example, you have saved a long paragraph in a file. And you want to search if a particular block of String is present in it or not.
Or maybe you have stored some data in a Collection(Say, List, Set e.t.c.).
Well! We have seen some ways of searching the data. But now, let us see a better one.
And as said, Regex provides a better searching experience with some pattern.
Note : Don't get panicked by the below Functions. We will provide a detailed explanation for the below Functions, once we start learning the Regex patterns.
-
scan()
scan() Method returns the searched results as an Array.
-
match()
match() Method returns a Match Data if the pattern is matched.
-
split()
split() Method returns the searched results as an Array, splitted by the search pattern.
-
sub()
The sub() Method is used to replace the first occurrence of the searched pattern with a given text.
-
gsub()
The gsub() Method is used to replace the searched pattern with a given text.
In the next tutorial, let us look Regex Patterns and see how the above Functions works.
