Soap Parsing in Windows Phone 8 c#

Introduction

SOAP, originally defined as Simple Object Access Protocol, is a protocol specification for exchanging structured information in the implementation of Web Services in computer networks. It relies on XML Information Set for its message format, and usually relies on other Application Layer protocols, most notably Hypertext Transfer Protocol (HTTP) or Simple Mail Transfer Protocol(SMTP), for message negotiation and transmission.

 However This section explains how to use the SOAP functions to parse information from incoming requests.

Building the Sample

No need of any other external dll's or library.We just need to add following helper class for removing the extra name spaces from soap reponce 

1)Removing soap name space's and making the proper xml nodes

Removing the namespaces from SOAP request in windows phone 8 c#

                   (or)
How to parse soap responce into xml nodes in windows phone 8 c#

C#

 public class RemoveNameSpace 
    { 
 
        public static string RemoveAllNamespaces(string xmlDocument) 
        { 
            XElement xmlDocumentWithoutNs = RemoveAllNamespaces(XElement.Parse(xmlDocument)); 
 
            return xmlDocumentWithoutNs.ToString(); 
        } 
 
        private static XElement RemoveAllNamespaces(XElement xmlDocument) 
        { 
            if (!xmlDocument.HasElements) 
            { 
                XElement xElement = new XElement(xmlDocument.Name.LocalName); 
                xElement.Value = xmlDocument.Value; 
                return xElement; 
            } 
            return new XElement(xmlDocument.Name.LocalName, xmlDocument.Elements().Select(el => RemoveAllNamespaces(el))); 
        } 
 
    }

 Example for use this class:

 string Notificationdata = RemoveNameSpace.RemoveAllNamespaces(reader.ReadToEnd()); 

2)Creating Ui for showing responce data

XAML

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"> 
            <ListBox HorizontalAlignment="Left" Name="aboutlist" Height="696" VerticalAlignment="Top" Width="456"> 
                <ListBox.ItemTemplate> 
                    <DataTemplate> 
                        <Grid Width="456"> 
                            <Grid.RowDefinitions> 
                                <RowDefinition Height="Auto"/> 
                                <RowDefinition Height="Auto"/> 
                                <RowDefinition Height="Auto"/> 
                                <RowDefinition Height="Auto"/> 
                            </Grid.RowDefinitions> 
                            <TextBlock TextWrapping="Wrap" Grid.Row="0" Text="{Binding Text3}"/> 
                            <TextBlock TextWrapping="Wrap" Grid.Row="1" Text="{Binding Text2}"/> 
                            <TextBlock TextWrapping="Wrap" Grid.Row="2" Text="{Binding Text1}"/> 
                            <Rectangle Fill="White" Height="10" Grid.Row="3"/> 
                        </Grid> 
                    </DataTemplate> 
                </ListBox.ItemTemplate> 
            </ListBox> 
        </Grid>

3)ScreenShot

Description

Note: Here i am using "HttpWebRequest" for requesting the web service.You may also try to request the web service using WebClient. However in this sample i had taken Url is "http://sygnetinfosol.com/webservice.asmx".and i don't give guarantee for this url will work in future.And so please replace this url with your own web service url

We have to follow some little bit steps to parse the soap response
1)Creating HttpWebRequest object request

C#

HttpWebRequest spAuthReq = HttpWebRequest.Create("http://sygnetinfosol.com/webservice.asmx") as HttpWebRequest;

2)Need to mention Soap action

C#

spAuthReq.Headers["SOAPAction"] = "http://tempuri.org/HelloWorld";//here i want call the hellworld method so i kept this soap action

 3)Need to mention content type

C#

 spAuthReq.ContentType = "text/xml; charset=utf-8";

4)Generating the soap request

C#

string AuthEnvelope = 
                          @"<?xml version=""1.0"" encoding=""utf-8""?> 
            <soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/""> 
            <soap:Body> 
            <HelloWorld xmlns=""http://tempuri.org/"" /> 
          </soap:Body> 
            </soap:Envelope>";

5)Removing the namespace from soap response with above helper class name is "RemoveNameSpace"

C#

 string Notificationdata = RemoveNameSpace.RemoveAllNamespaces(reader.ReadToEnd()); 

 6)Total code is
