How can an external table handle data with line feed between delimiters?

Question

I have defined an external table as below. My data is pipe delimited and comes from a DOS system.
I already remove any carriage returns before putting the file into the DATA_DIR for reading. But
I have found that some of my VARCHAR fields have embeded line feeds.
Is it possible to have a definition that would remove any line feed characters between the delimiters?
Below I also threw together a sample data set there ID #2 has that extra character. Yes, I could
write an awk script to pre-process all my data files. But I am hoping there is a way for Oracle
to also do this.
I understand the LDTRIM to remove any leading and trailing spaces in the delimited field. Is there a
REPLACE or TRANSLATE option. I did a bit of searching but I must be asking the wrong things.
Thanks for any help

Answer 1

Thanks for looking. But that relates to the record delimiter which in my case is the pipe character '|'. In my various data sets this is consistent. I expect each record to be one per line. But between two delimiters some data has a line feed. So I'm looking for a method that will "cleanup" the field data as it gets imported.
I was hoping there was an option that would ignore any embedded line feeds (\n) characters. I.e., those not at the end of the line.
