I have a three-line input file like this:
TEST 1
TEST 2
TEST 3
[blank line here]
How do I instruct the DFDL parser to ignore that blank last line and not throw this:
May 5, 2014, 3:01:04 PM fatal: CTDP3002E: Unexpected data found at offset 'blah' after parsing completed. Data: '0x0d...'. |

Set the group terminator to new line, can be omitted.

Can you be more specific? The wizard gave me 4 levels:
MyFormat
..sequence
....body
......sequence
........data elements start here
I can set terminators and initiators at each of these levels. I tried setting Terminator at a couple of these levels to {$dfdl:outputNewLine} but I can't change Document Final Terminator Can Be Missing from 'no'. |

| I might have accidentally gotten this to work. There were a bunch of extra settings specified at those various levels I mentioned once I exited the wizard. I tweaked each of those (i.e. removed most of them), and just set CRLF at the sequence level just above the data elements. Things appear to be working now... will keep working and post back here if problems arise. |

You need to model the final newline character(s) as a terminator ( not a separator ), and then make sure that you set documentFinalTerminatorCanBeMissing="yes".
You can still model the other newlines as separators if you like - just make sure that the optional terminator is defined on the outermost element.

Thanks for the reply... I'm looking around, but not seeing the documentFinalTerminatorCanBeMissing property. And when you say final newline character, would that be on the outermost element, or the body, or...?

Should be on the first sequence, I think.

Looks like it is on the data format, and can only be changed thereon.
Collapse all sections of your DFDL document..., navigate to the format section and edit or copy your data format.
On the dataformat details you will find Document Final terminator can be missing: set the value to yes
If your record is defined by a terminator, you will see the terminator has children. The omit last terminator is a child of the terminator...
Apply the dataformat you created to the message / sequence where you defined the documents Final Terminator...

You can set the 'documentFinalTerminatorCanBeMissing' property as follows:
- Click the 'Show all sections' button at the top of the DFDL editor
- Find the 'Data Formats' section
- Click on the <default format> entry
- You should now see the full set of DFDL properties display in the 'Representation properties' view on the right hand side.
- Find the 'Delimiters' section. The property 'DocumentFinalTerminatorCanBeMissing' is listed there.
After changing the property and saving, feel free to look at the xsd in a text editor. You should find that the anonymous format block for the schema has been changed to include the new property. |
