node.js - Extract values from nested XML using Node JS -

i'm writing rest service in node takes xml input, when parse it, 1st level nodes displayed, nested ones displayed objects.

i cannot hard-code xml elements read because per specification there optional elements, has dynamic.

i'm using body-parser-xml parse xml.

var express = require('express'),     bodyparser = require('body-parser');  require('body-parser-xml')(bodyparser);  //var xmlparser = require('express-xml-bodyparser');  var app = express();  app.use(bodyparser.xml({   limit: '1mb',   // reject payload bigger 1 mb    xmlparseoptions: {     normalize: true,     // trim whitespace inside text nodes      normalizetags: true, // transform tags lowercase      explicitarray: false, // put nodes in array if >1      preservechildrenorder: true   } }));  // app.use(xmlparser());  app.post('/users', function(req, res, body) {   // request xml payload parsed    // , javascript object produced on req.body    // corresponding request payload.    console.log(req.body);   var parsedxml = req.body;   console.log(parsedxml.classes);   res.status(200).end(); });  var http = require('http'); http.createserver(app).listen(3000); 

my xml input rest

<?xml version="1.0" encoding="utf-8"?> <schools> <school>     <name>some name</name>     <city>some city</city>     <classes>         <class>             <name>class 1</name>             <onroll>20</onroll>             <students>                 <student>                     <name>student 1</name>                     <age>10</age>                 </student>                 <student>                     <name>student 2</name>                     <age>11</age>                 </student>             </students>         </class>         <class>             <name>class 2</name>             <onroll>30</onroll>             <students>                 <student>                     <name>student 21</name>                     <age>12</age>                 </student>                 <student>                     <name>student 22</name>                     <age>13</age>                 </student>             </students>         </class>     </classes>     <labs>         <lab>             <name>science lab 1</name>             <subject>physics</subject>         </lab>         <lab>             <name>science lab 2</name>             <subject>chemistry</subject>         </lab>     </labs>     </school> </schools> 

and output

d:\tryouts\myapp>node xmlparser.js { schools:    { school:       { name: 'some name',         city: 'some city',         classes: [object],         labs: [object] } } } undefined 

basically i'm looking @ automatically read nested xml , display it.

i'm using chrome rest plugin invoke service http://localhost:3000/users method post , content-type application/xml.

requesting resolve this.

you may want use , nice util package. try this:

const util = require('util'); // parse xml file    console.log(util.inspect(parsedxml.classes, { depth: null, showhidden: false })); 

hope helps.
