Package Exports

fast-xml-parser

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fast-xml-parser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

fast-xml-parser

Parse XML to JS/JSON very fast without C/C++ based libraries and no callback

How to use

Installation $npm install fast-xml-parser or using yarn $yarn add fast-xml-parser

Usage

var fastXmlParser = require('fast-xml-parser');
var jsonObj = fastXmlParser.parse(xmlData);

// when a tag has attributes
var options = {
        attrPrefix : "@_",
        textNodeName : "#text",
        ignoreNonTextNodeAttr : true,
        ignoreTextNodeAttr : true,
        ignoreNameSpace : true
    };
var jsonObj = fastXmlParser.parse(xmlData,options);

//Intermediate obj
var tObj = fastXmlParser.getTraversalObj(xmlData,options);
var jsonObj = fastXmlParser.convertToJson(tObj);

To use from command line

$xml2js [-ns|-a] <filename> [-o outputfile.json]

To use it on webpage

Download and include parser.js

var jsonObj = xml2json(xmlData);

Give me a star, if you really like this project.

I decided to created this library when I couldn't find any library which can convert XML data to json without any callback and which is not based on any C/C++ library.

Liraries that I compared

xml-mapping : fast, result is not satisfactory
xml2js : fast, result is not satisfactory
xml2js-expat : couldn't test performance as it gives error on high load. Instalation failed on traivs and on my local machine using 'yarn'.
xml2json : based on node-expat which is based on C/C++. Instalation failed on travis.
fast-xml-parser : very very fast.

Why not C/C++ based libraries? Instalation of such libraries fails on some OS. You may require to install missing dependency manually.

Don't forget to check the performance report on comparejs.

Limitation

This tool doesn't check if the XML is valid or not. If the XML is not valid you may get invalid result.
