Function: parseXtn()

parseXtn(rep, enc): XTN

Parse an HL7 v2 XTN repetition into a structured XTN object. Components are returned verbatim (already decoded once by the tokenizer: never re-unescaped). Absent / empty components are OMITTED from the result (exactOptionalPropertyTypes semantics). Components past position 12 are silently ignored in v1.

Parameters

rep

RawRepetition

enc

EncodingCharacters

Returns

XTN

Example

import { parseXtn, DEFAULT_ENCODING_CHARACTERS } from "@cosyte/hl7";
const rep = { components: [
  { subcomponents: ["555-1234"] },
  { subcomponents: ["PRN"] },
  { subcomponents: ["PH"] },
] };
const xtn = parseXtn(rep, DEFAULT_ENCODING_CHARACTERS);
console.log(xtn.telephoneNumber); // "555-1234"
