What is Regular Expressions, an Introduction to Regular Expressions

They are often used to perform complex search-and-replace operations, and to validate that text data is well-formed.

The default behavior of most regular expression engines is to return just the first match. Though this regex can match the second "o" too. Most regex implementations provide a mechanism by which we can obtain a list of all matches when the regex engine start searching through the string after the first match.

What is Regular expression engines
