here code 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 tell me might issue here?

is there better npm module ..?

you can parse xml json, replace need, , save xml.

for example, @ 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);      }); });
