This document describes several string matching operations in DataWeave including matches, startsWith, endsWith, find, match, and similar. It provides examples of the operations by showing DataWeave code that defines the operation, applies it to sample data, and outputs the results as JSON.

- 1. Data weave more operations
- 2. Matches • (':string', ':regex') ⇒ ':boolean' • Matches a string against a regular expression, and returns true or false. • %dw 1.0 • %output application/json • --- • b: "admin123" matches /(d+)/
- 3. Transform and output • { "b": false }
- 4. Starts With Returns true or false depending on if a string starts with a provided substring. • %dw 1.0 • %output application/json • --- • { • a: "Mariano" startsWith "Mar", • b: "Mariano" startsWith "Em" • }
- 6. Ends With • Returns true or false depending on if a string ends with a provided substring. • %dw 1.0 • %output application/json • --- • { • a: "Mariano" endsWith "no", • b: "Mariano" endsWith "to" • }
- 8. Find • Given a string, it returns the index position within the string at which a match was matched. If found in multiple parts of the string, it returns an array with the various idex positions at which it was found. You can either look for a simple string or a regular expression.
- 10. Match • Match a string against a regular expression. Match returns an array that contains the entire matching expression, followed by all of the capture groups that match the provided regex.
- 12. Similar • Evaluates if two values are similar, regardless of their type. For example, the string "1234" and the number 1234 aren’t equal, but they are recognized as similar.
