The code given in the book for XMLBuilder DLS returns the below output - not the one given in the book:

Eich

Gosling

Matz

The below else part of the toString method -

“”"$indent<$name$attributesValues>
|${children.joinToString("\n") { it.toString(indentation + DEPTH) }}
|$indent</$name>""".trimMargin()

has to be changed a bit, with joinToString taking a prefix of a new line (\n) along with the new line separator, like below -

“”"$indent<$name$attributesValues>
|${children.joinToString("\n")("\n") { it.toString(indentation + DEPTH) }}
|$indent</$name>""".trimMargin()

To get the necessary output:

Please correct me if I am wrong.

Thanks.
