i tried to obtain the xml element from xml file using xml-js library in nodejs. but when i tried to get the element inside the xml that has colon like this code below, i can't obtain the element

<gml:boundedBy>
        <gml:Enve srsDimension="3" srsName="EPSG:31467">
        </gml:Enve>      
</gml:boundedBy>

and this is javascript code i use

const convert = require('xml-js');
const fs = require('fs');

// read file
const xmlFile = fs.readFileSync('georef.xml', 'utf8');

// parse xml file as a json object
const jsonData = JSON.parse(convert.xml2json(xmlFile, {compact: true, spaces: 2}));

const targetNode = jsonData.['gml:boundedBy'].['gml:Enve']
console.log(targetNode._attributes.srsName);  // outputs: 2

and i got this code above from this link
