Bugs are evident™ - MATRIX️

NodeJS LTS is supported

Built on NodeJs version

v22.3.0

Description

Simple XML2JSON Parser

The info about the fork

The buglabs#180 maintainers (buglabs, no e-mail, no GitHub) are not responsive. So, I created a small fix, that works perfectly, it is named as p3x-xml2json. It is the same as the original, just works with NodeJs 12.
I am open to merge pull requests. I maintain. Please free, to contact me.

Besides, I have upgraded all packages to the latest versions.

Verbose description

It does not parse the following elements:

• CDATA sections (*)
• Processing instructions
• XML declarations
• Entity declarations
• Comments

This module uses node-expat which will require extra steps if you want to get it installed on Windows. Please refer to its documentation.

Installation

$ npm install p3x-xml2json

Usage

var parser = require('p3x-xml2json');

var xml = "<foo attr=\"value\">bar</foo>";
console.log("input -> %s", xml)

// xml to json
var json = parser.toJson(xml);
console.log("to json -> %s", json);

// json to xml
var xml = parser.toXml(json);
console.log("back to xml -> %s", xml)

API

parser.toJson(xml, options);

parser.toXml(json);

Options object for toJson

Default values:

var options = {
    object: false,
    reversible: false,
    coerce: false,
    sanitize: true,
    trim: true,
    arrayNotation: false
    alternateTextNode: false
};

• object: Returns a Javascript object instead of a JSON string
• reversible: Makes the JSON reversible to XML (*)
• coerce: Makes type coercion. i.e.: numbers and booleans present in attributes and element values are converted from string to its correspondent data types. Coerce can be optionally defined as an object with specific methods of coercion based on attribute name or tag name, with fallback to default coercion.
• trim: Removes leading and trailing whitespaces as well as line terminators in element values.
• arrayNotation: XML child nodes are always treated as arrays NB: you can specify a selective array of nodes for this to apply to instead of the whole document.
• sanitize: Sanitizes the following characters present in element values:

var chars =  {
    '<': '&lt;',
    '>': '&gt;',
    '(': '&#40;',
    ')': '&#41;',
    '#': '&#35;',
    '&': '&amp;',
    '"': '&quot;',
    "'": '&apos;'
};

• alternateTextNode: Changes the default textNode property from $t to _t when option is set to true. Alternatively a string can be specified which will override $t to what ever the string is.

Options object for toXml

Default values:

var options = {
    sanitize: false,
    ignoreNull: false
};

• sanitize: false is the default option to behave like previous versions
• ignoreNull: Ignores all null values

(*) xml2json tranforms CDATA content to JSON, but it doesn't generate a reversible structure.
