[Ruby-hl7-users] Empty sections?

[Christian Baumann]

Hello,

I´ld like to know how to handle empty segments?
Everytime I try to create a Message-object with the following code:

raw_input = open( "sample.hl7" ).readlines
msg = HL7::Message.new( raw_input )

I get this error message:

c:/ruby/lib/ruby/gems/1.8/gems/ruby-hl7-0.1.23/lib/ruby-hl7.rb:253:in `generate_segments': undefined method `to_sym' for nil:NilClass (NoMethodError)
