Scala 模式修补以替换每第二次出现

Question

I have a string that looks like the one below.

{"module":"page1":"action":"save":"FirstName":"John”}

I would like to replace every second ":" into "," to make it a valid JSON.

Could somebody please suggest on how I can achieve this scala. In this example, there are only 3 key=value pairs, but there can be more than 3 as well.

Expected:

{"module":"page1","action":"save","FirstName":"John”}

Thanks in advance

This should do it.

"""("\w*":"\w*"):""".r.replaceAllIn(str, "$1,")
