These topics introduce the concept of regular expressions and explain how to create and use them in JScript.
A regular expression describes one or more strings to match when you search a body of text. The expression serves as character pattern to compare with the text being searched. You can use regular expressions to search for patterns in a string, replace text, and extract substrings.
Clarifies how pattern-matching notation of regular expressions enables developers to quickly search large amounts of text to find specific character patterns; to extract, edit, replace, or delete text substrings; or to add extracted strings to a collection to generate a report.
