Strings and Parser Method

• Ruby deals with strings as well as numerical data. A string may be double-quoted ("...") or single-quoted ('...').

Expression Substitution:

• Expression substitution is a means of embedding the value of any Ruby expression into a string using #{ and }.

Example:

General Delimited Strings:

• With general delimited strings, you can create strings inside a pair of matching though arbitrary delimiter characters, e.g., !, (, {, <, etc., preceded by a percent character (%). Q, q, and x have special meanings.
  

Ruby Parser:

• The Gosu and Nokogiri gem is a fantastic library that serves virtually all of our HTML scraping needs. Once you have it installed, you will likely use it for the remainder of your web-crawling career.

Example :

• I have taken Stona FIGSI 2016 website for doing parser string manipulations in Ruby programming language.

And here is the output for the above code :
