Angular: Convert XML to JSON

Question

I have this method where I receive an XML response from a remote server and I need to convert the XML to JSON so that Angular 2 can work with the data:

 priv         


        

Answer 1

If you use angular-cli to bootstrap your application - it comes already with node module to convert xml.

https://github.com/Leonidas-from-XIV/node-xml2js

So you do not need to add extra modules for this. As it is classic commonJS module - you need use require to import it:

let parseString = require('xml2js').parseString;

So your code can looks like:

let parseString = require('xml2js').parseString;
let xml = "<root>Hello xml2js!</root>"

parseString(xml, function (err, result) {
  console.dir(result);
});

You will receive next output:

In any cases - if you even do not use angular-clior want to use your preffered module to parse xml - use require to load it.

Answer 2

function parseXml(xmlStr) {
    var result;
    var parser = require('xml2js');
    parser.Parser().parseString(xmlStr, (e, r) => {result = r});
    return result;
}

Answer 3

As xml2js uses sax as parser and is a native c module, I would recommend using txml. In your bundle it will only be 4kb and the api is very clean: txml.parse(xmlString)
