Concept: Regular Expressions in Prism
Regular expressions vary in complexity using a combination of basic constructs to
describe a string matching pattern. This reference describes the most common regular expression
matching patterns, but is not a comprehensive list.
Regular expressions, also referred to as regex or regexp, are a
standardized collection of special characters and constructs used for matching strings of
text. They provide a flexible and precise language for matching particular characters, words,
or patterns of characters.
Prism Analytics regular expressions are based on the pattern matching syntax of the Java
programming language. For more in depth information on writing valid regular expressions,
refer to the Java regular expression pattern
documentation.
You can use regular expressions in Prism calculated field expressions that use either the
REGEX
or REGEX_REPLACE
functions.
