In this blog, we will explore how conditional statements can be implemented with For Each in MuleSoft.
Understanding Conditional Statements
Conditional statements are used to execute specific code based on certain conditions. In MuleSoft, conditional statements are commonly used to filter and process data based on certain criteria. The most commonly used conditional statements are If-else, Switch and When statements.
Using Conditional Statements with For Each
The For Each loop can be used to iterate over a collection of data and execute specific code based on certain conditions. By using conditional statements within the loop, developers can filter and process data based on specific criteria. This can help businesses connect and integrate systems that use different data formats, such as JSON, XML, or CSV.
For example, consider a scenario where an API returns a JSON array of customer data, and we want to process only the records where the customer age is greater than 18. We can achieve this by using the For Each loop and an If-else statement.
Here is an example code snippet:
<foreach collection="#[payload]" doc:name="For Each"> <choice doc:name="Choice"> <when expression="#[payload.age > 18]"> <!-- Process the record --> </when> <otherwise> <!-- Skip the record --> </otherwise> </choice> </foreach>
