How to print $dollarin the output ? in MuleSoft

In MuleSoft 4, directly printing a literal dollar sign ($) in the output payload requires escaping the character to prevent it from being interpreted as a special character. Here's how to achieve this:

Escaping the Dollar Sign:

There are two main methods to escape the dollar symbol and print it as plain text:

1. Using Backslash:

• Precede the dollar sign with a backslash (\). This instructs the system to treat the following character literally.

Example:

XML

<set-payload value="This string contains \$100." doc:name="Set Payload" />

Explanation:

• The backslash (\) escapes the dollar sign, preventing it from being interpreted as a special character.

• The resulting output will be: "This string contains $100."

2. Using Unicode Escape Sequence:

• Utilize the Unicode escape sequence for the dollar sign: $.

Example:

XML

<set-payload value="This string contains $100." doc:name="Set Payload" />

Explanation:

• The Unicode escape sequence $ represents the dollar sign character.

• The resulting output will be identical to the previous method: "This string contains $100."

Choosing the Right Approach:

• Both methods are effective. Using a backslash is generally simpler and more concise.

• Unicode escape sequences might be preferred in specific scenarios where broader character encoding compatibility is required.

Additional Considerations:

• The chosen method should be consistent throughout your Mule application to avoid potential issues.

• If you're working with DataWeave, you can directly include the dollar sign without escaping within string literals.

Example (DataWeave):

%dw 2.0
---
output = "This string contains $" ++ "100."

Important Note:

While these methods allow you to print the dollar sign as plain text, it's crucial to understand that the actual functionality or interpretation of the dollar sign within your application might depend on the context and the specific component you're using.

For instance, if you're using the dollar sign within a financial context to represent currency, you might need additional logic or specific formatting based on your requirements.
