Provide an example of parsing a segment_field and/or subfield from the message column

[MartinChavezNC]

Given a dataframe that loads the HL7 files, can you provide an example of parsing a segment_field and/or subfield from the message column?

val repro = spark.read.format("hl7").load("...")

Would love to see an example as well. In my particular case, the event id is in the message header and that is needed to define schema of segments

Message is stored as a string so you can parse the header information in it with native Spark split() functions to get what you need.
