Description

The XMLParser fails when stopNode is an empty (self-closing) tag. If I remove the problematic tag, everything works fine.

Input

<?xml version="1.0"?>

Code

import { X2jOptionsOptional, XMLParser } from 'fast-xml-parser';
import { readFile, writeFile } from 'fs/promises';

const PATH = `${__dirname}/ControleAcionario.xml`;

const ignoreTags = [
  /ControlesAcionariosAcionistasFilhos/i,
];

/**
 * I have also tried with:
 * ArrayOfControleAcionarioAcionista.ControleAcionarioAcionista.ControlesAcionariosAcionistasFilhos
 */
const stopNodes = [
  '*.ControlesAcionariosAcionistasFilhos',
];

const tagValueProcessor = (tagName: string, tagValue: string, jPath: string) => {
  if (ignoreTags.some((re) => re.test(jPath))) return '';
  return tagValue;
};

const options: X2jOptionsOptional = {
  tagValueProcessor,
  trimValues: true,
  stopNodes,
};

(async () => {
  const parser = new XMLParser(options);
  const xml = (await readFile(PATH)).toString();
  const json = JSON.stringify(parser.parse(xml), null, 2);
  await writeFile(`${__dirname}/test.json`, json);
})();
