Dataweave - 字符串数组删除方括号

Dataweave - String array remove square brackets

我得到这个字符串数组:

["HELLO","WORLD"]

我想输出相同但没有方括号:

"HELLO","WORLD"

如何在 Mule 中用 Dataweave 替换或转换它?

可能的解决方案(在评论中归功于@jerney)

使用索引操作:

%dw 1.0
%output application/java

%var input = "[\"HELLO\", \"WORLD\"]"
---
input[1..-2]

使用正则表达式:

%dw 1.0
%output application/java

%var input = "[\"HELLO\", \"WORLD\"]"
---
input replace /^\[|\]$/ with ""

使用简单替换:

%dw 1.0
%output application/java

%var input = "[\"HELLO\", \"WORLD\"]"
---
input replace "[" with "" replace "]" with ""
