It offers more features than xml-parser, such as support for XML namespaces and the ability to customize the parsing process with options. xml2js is more feature-rich and configurable compared to the simpler xml-parser.

fast-xml-parser

fast-xml-parser is another XML parser for Node.js that is known for its performance. It provides fast parsing of XML data into JavaScript objects and supports various options for customization.

sax

sax is a streaming XML parser for Node.js that provides an event-driven API. It is suitable for parsing large XML files as it processes the data in chunks. Unlike xml-parser, which parses the entire XML string at once, sax allows for more control over the parsing process and is ideal for handling large or complex XML data.

README

xml-parser

Simple non-compiant XML parser because we just need to parse some basic responses and libxml takes forever to compile :D you probably don't want to use this unless you also have similar needs.

Installation

$ npm install xml-parser

Example

JavaScript:

var fs = require('fs');
var parse = require('xml-parser');
var xml = fs.readFileSync('examples/developerforce.xml', 'utf8');
var inspect = require('util').inspect;

var obj = parse(xml);
console.log(inspect(obj, { colors: true, depth: Infinity }));

XML:

<?xml version="1.0" encoding="utf-8"?>
 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
   xmlns="urn:enterprise.soap.sforce.com">
   <soapenv:Body>
      <createResponse>
         <result>
            <id>003D000000OY9omIAD</id>
            <success>true</success>
         </result>
         <result>
            <id>001D000000HTK3aIAH</id>
            <success>true</success>
         </result>
      </createResponse>
   </soapenv:Body>
 </soapenv:Envelope>

Yields:

{ declaration: { attributes: { version: '1.0', encoding: 'utf-8' } },
  root:
   { name: 'soapenv:Envelope',
     attributes:
      { 'xmlns:soapenv': 'http://schemas.xmlsoap.org/soap/envelope/',
        xmlns: 'urn:enterprise.soap.sforce.com' },
     children:
      [ { name: 'soapenv:Body',
          attributes: {},
          children:
           [ { name: 'createResponse',
               attributes: {},
               children:
                [ { name: 'result',
                    attributes: {},
                    children:
                     [ { name: 'id',
                         attributes: {},
                         children: [],
                         content: '003D000000OY9omIAD' },
                       { name: 'success', attributes: {}, children: [], content: 'true' } ],
                    content: '' },
                  { name: 'result',
                    attributes: {},
                    children:
                     [ { name: 'id',
                         attributes: {},
                         children: [],
                         content: '001D000000HTK3aIAH' },
                       { name: 'success', attributes: {}, children: [], content: 'true' } ],
