How to get value from XML string using Node.js

Let's say you have this xml:

<yyy:response xmlns:xxx='http://domain.com'> 
    <yyy:success> 
        <yyy:data>some-value</yyy:data> 
    </yyy:success> 
</yyy:response>

How do I get the value between <yyy:data>using Node.js?

Thank.

node-xml2js will help you.

var xml2js = require('xml2js');

var parser = new xml2js.Parser();
var xml = '\
<yyy:response xmlns:xxx="http://domain.com">\
    <yyy:success>\
        <yyy:data>some-value</yyy:data>\
    </yyy:success>\
</yyy:response>';
parser.parseString(xml, function (err, result) {
    console.dir(result['yyy:success']['yyy:data']);
});

You can make it easier with Camaro

const camaro = require('camaro')

const xml = '<yyy:response xmlns:xxx='http://example.com'> <yyy:success><yyy:data>some-value</yyy:data> </yyy:success></yyy:response>'

const template = {
    data: '//yyy:data'
}

console.log(camaro(xml, template))

Output:
