Nodejs Soap api call returns "Unexpected root element of WSDL or include"

Question

I am trying to access a web api using node-soap module, but every time i run the code i get following error "Unexpected root element of WSDL or include"

var soap = require('soap');
var xml2js = require('xml2js');

var url = 'https://webservice.servcei.com/LoginXML';
var params = {
    Username:'webservice',
    Password:'Test123'
};
soap.createClient(url,params,function(err,client){
    console.log(err);
});

Answer 1

The "url" variable should point to WSDL, not the web service itself. By convention WSDL should be located on following URL: https://webservice.servcei.com/LoginXML?wsdl

So do following:

1. Check if you can access the WSDL on following URL: https://webservice.servcei.com/LoginXML?wsdl. If not, find the correct location of WSDL file
2. Check the service host is specified in WSDL xml. If not use "endpoint" parameter of createClient to point to real SOAP service.
