Hello Experts,
IIB 10.0.0.9
Windows

I am consuming a webservice where I receive Base64Binary string response in one element.
I have to write this Base64Binary string to a file. I have created dfdl and defined an element as string and representation as text.
Dfdl doesn't support Base64Binary type elements.
How do I write Base64Binary value to a file?
Thanks

Why are you using the DFDL parser for this data? Are you modifying the message tree before you write it to the file? Are you changing the text encoding?
If the answer to both of those questions is 'no' then you can just use the BLOB domain to write the received bytes into the file.

By definition, a Base64 encoded string consists of printable ASCII characters, it does not contain any strange binary codes. Or am I missing something here?

No, you're not missing anything. Base64 is just characters. But if the message flow is not modifying those characters, then there is no point in parsing them at all. So the BLOB domain is the correct choice.
