Generating new line inside of Generate Data operator
Guru
We currently generate text that is parsed into an XML for third party software. This software does not follow the conventions for line breaks and utilised the characters inside of the text field to split the lines.
We need to generate the following:
Get what
you want
When using the generate data operator and then the extract document operator the above gets turned into:
Get what you want
(There are two spaces (Hex: 20 20) instead of a line break (Hex: 0D 0A))
How do I correctly generate the line break using this operator?

Hi,Less convoluted, but requires a short script is the process below. I was actually somewhat surprised that there is no way to add a new line character in any form (Java, Unicode, whatever) in the parameters. But then again: How could we without introducing a special symbol or some form of quoting? It would just be represented as a new line in the underlying XML otherwise...Anyway, here are some "solutions" although I freely admit that they are all a bit weird
