To make use of flat files, Biml will require one or more flat file formats as well as the corresponding flat file connections. A flat file connection is nothing but a link between a flat file format and the path to a flat file. While in real life, you might rather want to loop across multiple files using the same format, we’ll keep it simple for now and assume that we’ll have one file per format (which is the case here anyway due to our AdventureWorks sample data).
For reasons of readability and also the ability to easily reuse our code, we’ll make use of a new extension method called GetFlatFileFormatfromXML. If you have not read our post on creating your own extension methods, you may want to do that first.
Getting the extension method in place is about 90% of the solution. Read on to see the whole thing.
