What DataWeave expression transforms the array a to the XML output?

Show Suggested Answer Hide Answer
Suggested Answer: A

For such questions always look for Syntax:

I call it 'Wrap the Map'

trains:

{(

When mapping array elements (JSON or JAVA) to XML, wrap the map operations in {(..)}

-{ } are defining the object

-( ) are transforming each element in the array as a key/value pair

I've seen similar questions before, so I think I have a good strategy for this. I'll start by breaking down the problem and identifying the key elements I need to address in my DataWeave expression.

I'm a bit confused by the formatting of the options. I'll need to parse through them line by line to make sure I understand the syntax correctly. This is a good opportunity to practice my DataWeave skills.

Document steps, email steps, database steps - those all sound like reasonable options. But I'm not confident any of those are the correct answer. Guess I'll have to eliminate the ones I'm less sure about.

I'm pretty confident that Selenium is a tool for automating web testing, not for designing or implementing test cases. I think option D is the best answer here.
