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"
• }

5. Transform and output

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"
• }

7. Transform and output

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.

9. Transform and output

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.

11. Transform and output

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.

13. Transform and output
