Parsing a XML Document

Question

I am using Visual Studio 2010 Ultimate Evaluation. In the "Web test" environment
I have a web service called "Add".
It simply takes 2 numbers, sums them, and gives a result. (example 1+1)
The result is loaded in a stand-alone page with a URL "http://localhost:xxxx/MathService.asmx/Add
And the result is given by xML :
<?xml version="1.0" encoding="utf-8" ?>

My Question is "how do I parse the result ,2, within the XML"?

I am a newbie at C#

You are using webService you dont need to parse Result of method you can Call method By simply Creating Intance of WebService and call the method like below public static void Main(String[] args) { MyService mySvc = new MyService(); Console.WriteLine(Calling Add(2 3) Service:  + mySvc.Add(2 3).ToString()); }

Ok I have attached a zip file of my project. Things to know: The web service ADDS 2 values (a and b) from an Excel spreadsheet called Math.csv (included in zip) The ADD Result is always given on a new page as an integer at the URL http://localhost:xxxx/MathService.asmx/Add And the URL result page will include the answer and will look like this : xml version=1.0 encoding=utf-8 ?> int xmlns = http://tempuri.org/  > 2 int > I want to always be able to parse the result...in this case 2

Provide me your Whole project with Webservice in (zip) at kirtan007@gmail.com i will look at it :)

I see what you mean but I want my code to execute dynamically for any result XML file. This web service always Adds two numbers so the code needs to be dynamic. How do I make the code dynamically read ALL data? The Add answer page is a URL http://localhost:xxxx/MathService.asmx/Add  that generates the answer XML...in this case the answer was 2 (example 1+1) xml version=1.0 encoding=utf-8 ?> int xmlns = http://tempuri.org/  > 2 int >

Hi  you have to take string XMLDataGotFromWebService =  xml version=1.0 encoding=utf-8 ?> int xmlns = http://tempuri.org/  > 2 int >; Whole String not first Line only to work Code .. Thanks :) thats why its not working ..

Web Test Code is attached

Here is my Web Service Test Code...You will see I am initially posting 3 values ab and Result from my CSV file Once I parse the xml for the result 2  then I want to compare it the the Result column in the CSV file... So essentially xml parsed string 2 == Result string 2 in CSV How does the code look for this? thanks !

Kirtan Patel · Answer

If you still want to do it by parsing then here i written code for it int result; string XMLDataGotFromWebService =  ; //Write data in XML File for Parsing File .WriteAllText( temp.xml  XMLDataGotFromWebService); //Load the File and Parse the Needed thing XmlDocument doc = new XmlDocument (); doc.Load( temp.xml ); foreach ( XmlNode n in doc.ChildNodes) { if (n.Name == int ) { result= int .Parse(n.InnerText); break ; } }

My intention is to get the result 2 from the webservice and compare it to a known expected value from a CSV spreadsheet I'd really like to parse the xml OR be able to use a rule to generate the C# code. Once I have the web service result 2 I will compare it to an expected value 2 loaded from a CSV spreadsheet. Example: Web Service result == (this.Context[ mathdata.MathData#csv.Result )].ToString());
