I want to read specific xml tag and update it.

here is the xml file

  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
  <widget id=".ionicframework.myapp450442" version="0.0.1" xmlns="" xmlns:cdv=".0">
   <name>myApp</name>
    <description>

    <preference name="webviewbounce" value="false"/>
    <preference name="UIWebViewBounce" value="false"/>
    <preference name="DisallowOverscroll" value="true"/>
    <preference name="android-minSdkVersion" value="16"/>
    <preference name="BackupWebStorage" value="none"/>
    <feature name="StatusBar">
     <param name="ios-package" value="CDVStatusBar" onload="true"/>
    </feature>
  </widget>

I followed this similar question on stack over flow but it did n't work for me.

here is the code which i used

   fs.readFile(configFile, 'utf-8',function(err, data) {
      if (err) {
         return console.log(err);
      }

      var name="<name>"+appName+"</name>";
      var cursor = "//cursor";
      var result = data.replace(/\/\/cursor/,name);

      fs.writeFile(configFile, result, 'utf-8', function(err) {
          if (err) return console.log(err);
      });
      fs.writeFile(appIconFile, icon, 'base64', function(err) {
          if (err) return console.log(err);
      });
  });

Can somebody tell me what might be the issue here?

is there any better npm module ..?

You can parse XML to JSON, replace the need, and save back to XML.

For example, look at xml2js module:

var fs = require('fs'),
    xml2js = require('xml2js'),
    util = require('util');

var parser = new xml2js.Parser(),
    xmlBuilder = new xml2js.Builder();

fs.readFile(configFile, function(err, data) {
    parser.parseString(data, function (err, result) {

        console.log(util.inspect(result, false, null))        

        result.widget.name = ['new name'];

        var xml = xmlBuilder.buildObject(result);

        fs.writeFile(configFile, xml);

    });
});

small changes in stdob's answer

var fs = require('fs'),
    xml2js = require('xml2js');

var parser = new xml2js.Parser(),
    xmlBuilder = new xml2js.Builder();

fs.readFile(configFile, function(err, data) {
    parser.parseString(data, function (err, result) {

        console.log(result)        

        result.widget.name = ['new name'];

        var xml = xmlBuilder.buildObject(result);

        fs.writeFile(configFile, xml);

    });
});

he used unnecessary module.
