This is the XML add-on for UN/EDIFACT module of edi4r (hence ’::E’)

It leaves all real work to the base classes. Only the UNA information is treated in a special way (as a "Parameter" element of the header) and dealt with here.

Methods

edi_split  

Classes and Modules

Class EDI::E::CDE
Class EDI::E::DE
Class EDI::E::EDISyntaxError
Class EDI::E::Interchange
Class EDI::E::Message
Class EDI::E::MsgGroup
Class EDI::E::Segment
Class EDI::E::UNA

Constants

Illegal_Charset_Patterns = Hash.new(/[^-A-Za-z0-9 .,()\/=!%"&*;<>'+:?\xa0-\xff]+/)   Use pattern for allowed chars of UNOC charset if none given explicitly

Public Instance methods

edi_split( str, s, e, max=0 )

Utility: Separator method for UN/EDIFACT segments/CDEs

The given string typically comprises an EDIFACT segment or a CDE. We want to split it into its elements and return those in an array. The tricky part is the proper handling of character escaping!

Examples: 

 CDE = "1234:ABC:567"        --> ['1234','ABC','567']
 CDE = "1234::567"           --> ['1234','','567']
 CDE = ":::SOMETEXT"         --> ['','','','SOMETEXT']
 Seg = "TAG+1++2:3:4+A?+B=C" --> ['TAG','1','','2:3:4','A+B=C']

NOTE: This function might be a good candidate for implementation in "C"

Also see: ../../test/test_edi_split.rb

str:String to split
s:Separator char (an Integer)
e:Escape / release char (an Integer)
max:Max. desired number of result items, default = all

Returns: 

  Array of split results (strings without their terminating separator)
