Occasional EOF

I have an odd situation. I am setting up several orchestrations for a government organization. They have a simple flatfile postfix/CRLF positional flat file coming in. I set up the xsd quickly and of course it works perfectly with sample data.

Once the actual data arrived for testing from many sources, it occasionally has an EOF (0X1A) at the end. Apparently management does not want to be bothered with forcing the other agencies to meet the agree upon schema so…. I have to come up with a solution. (deep breath)

My question is: Is there a way to ignore the EOF when it occurs.

I have tried adding an element outside the root and then setting the root to infix/CRLF. This works for the ones with the EOF but fails the ones without.
Of course wrapping everything in another root delimited by EOF only works for the ones that have EOF as well.

Any suggestions?

Thanks in advance,
Scott
