OK, now I understand a bit better...and then not. The output format to use depends on what the process who does the ingestion can handle or expects to be there. XML? RTF? Some flat file with markup other than XML?
If this is for an app crafted with VS you may want to look into generating resx files. There is the resgen tool (
https://msdn.microsoft.com/en-us/librar ... 2147217396) that can take a text file and craft a resx file from it. From what I get from the article the text file contains plain key/value pairs. That would address the content, but not the formatting.
If that's not it you need to wait for someone else to chime in, but from my experience of 20 years in software development I do not know of any standard means on how to accomplish this. While Flare has many benefits it seems to be not the right tool for this job.
A few years back I was working with a desktop app that used ini files and simple control characters (such as /b text /b for bold) in the value strings. We also used purely numerical keys so that the ini files could be spellchecked without tripping over the keys. Maybe that works?
