HL7 parser

Usage: How to parse a HL7 message

var hl7 = require('sam-utility').hl7;
var objMsg = new hl7.Message(strMsg);

objMsg has a number of properties like:

• messageType
• triggerEvent
• version
• length (the number of segments)

It also has methods to find segments:

• findSegment(:segmentName)
• findAllSegments(:segmentName)
• filterSegment(:callback) (callback = function(currentSegment, currentIndex) => bool)

How to parse a segment

var segment = new hl7.Segment(str);

segment has the following properties:

• name
• length (the number of fields)

It also supports get and set methods:

• get([fieldIndex, [fieldEntryIndex, [componentIndex, [subComponentIndex]]]])
• set(newValue, [fieldIndex, [fieldEntryIndex, [componentIndex, [subComponentIndex]]]])

How to parse a field

var field = new hl7.Field(str);

field also supports get and set methods:

• get([fieldEntryIndex, [componentIndex, [subComponentIndex]]])
• set(newValue, [fieldEntryIndex, [componentIndex, [subComponentIndex]]])

How to parse a component

var component = new hl7.Component(str);

component also supports get and set methods:

• get([componentIndex, [subComponentIndex]])
• set(newValue, [componentIndex, [subComponentIndex]])

sub-component is plain string
