Function: parseCx()

parseCx(rep, enc): CX

Parse an HL7 v2 CX repetition into a structured CX object. Components are returned verbatim (already decoded once by the tokenizer: never re-unescaped). Absent / empty components are OMITTED from the result (exactOptionalPropertyTypes semantics). Component 4 (assigningAuthority) is parsed as a nested HD; see component table in the CX interface JSDoc for the v1 simplifications on components 6/9/10.

Parameters​

rep​

RawRepetition

enc​

EncodingCharacters

Returns​

CX

Example​

import { parseCx, DEFAULT_ENCODING_CHARACTERS } from "@cosyte/hl7";
const rep = { components: [
  { subcomponents: ["123"] },
  { subcomponents: [""] },
  { subcomponents: [""] },
  { subcomponents: ["EPIC", "1.2.840.114350", "ISO"] },
  { subcomponents: ["MR"] },
] };
const cx = parseCx(rep, DEFAULT_ENCODING_CHARACTERS);
console.log(cx.idNumber);                       // "123"
console.log(cx.assigningAuthority?.namespaceId); // "EPIC"
