I have input containing a series of lines separated by newlines. Each line
contains fields separated by slashes. Here is a sample input:
.../24L-36R/...
.../24L /...
.../ - /...
Actually, I got the input from a Word document, i.e., I copied from Word and
pasted into a .txt file. Here's what I pasted:
.../24L-36R/...
.../24L /...
.../ - /...
Eek! See the problem? (I didn't see the problem for a long time) Instead of the
first and third fields containing three dots, they contain the Microsoft
ellipses symbol. Okay, my bad. Nonetheless, I expect Daffodil to tell me that I
have bogus symbols in the input. But Daffodil doesn't do that. Daffodil sent me
on a wild goose chase. Daffodil gave this error message:
[error] Parse Error: Failed to populate Line[1]. Cause: Parse Error: Failed to
parse infix separator. Cause: Parse Error: Found out of scope delimiter: '%NL;'
'?'
That is a horrible error message! It is completely misleading. Completely
wrong. I spent a huge amount of time trying to understand, "How in the world is
the newline separator out of scope?"
Can this be fixed please? I.e., can Daffodil provide a more useful error
message please?
Here is an excerpt from my DFDL schema:
