Best practice for converting FLAT file to XML in CPI

0 Kudos

Hello, I'm a newc to this community, and I need to convert a flat file (like the example provided below) into XML format in CPI. I've found various blogs that suggest using Groovy scripts, while others recommend a combination of Palette functions and Groovy scripts. I'm unsure about the best practice to follow in CPI for handling this kind of scenario.


Looking for assistance from the community to meet this requirement using the best practices in CPI. Any assistance would be highly appreciated.

Hi @ag3silaus,

Thanks for getting back to me. After reviewing your blog, it seems that we're currently treating the incoming message as a String, which will store the entire payload in memory. However, I need to handle large amounts of FLAT file data, which could potentially lead to processing time issues. Is it possible to use a Reader to read the data line by line within the same code? If so, could you please provide an example for reference?

Thanks and regards,
