A regular expression can be viewed as a small programming language with a specific function that locates substrings in a paragraph of text. Regular expressions allow you to quickly parse large amounts of text to find specific character patterns, extract, edit, replace, or delete text substrings, or add extracted strings to the collection. The basic syntax for regular expressions can be seen in simple, regular expressions (i), and in the regular expression of the English language (II.). The
