I want to get the value of a tag in mi app.config that is in the configuration of a trace listener

<?xml version="1.0" encoding="utf-8"?>

<configuration>

    <system.diagnostics>

        <sources>

            <source name="System.ServiceModel.MessageLogging" switchValue="Warning,ActivityTracing">

                <listeners>

                    <add type="System.Diagnostics.DefaultTraceListener" name="Default">

                        <filter type="" />

                    </add>

                    <add name="ServiceModelMessageLoggingListener">

                        <filter type="" />

                    </add>

                </listeners>

            </source>

        </sources>

        <sharedListeners>

            <add initializeData="c:softwareapp_messages.svclog" 

                 type="System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp">

                <filter type="" />

            </add>

        </sharedListeners>

        <trace autoflush="true" />

    </system.diagnostics>

    <startup> 

        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />

    </startup>

    <system.serviceModel>

      <diagnostics>

        <messageLogging      

          logMessagesAtTransportLevel="true"

          logMessagesAtServiceLevel="false"

          logMalformedMessages="true"

          logEntireMessage="true"

          maxSizeOfMessageToLog="65535000"

          maxMessagesToLog="500" />

      </diagnostics>



    </system.serviceModel>

  <runtime>

    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

      <dependentAssembly>

        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />

        <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />

      </dependentAssembly>

    </assemblyBinding>

  </runtime>

</configuration>

the Line that I wanna get is:

<add initializeData="c:softwareapp_messages.svclog" 

I need to modify the the app_messages.svclog and read and write like this:

string logFilePath = ConfigurationManager.sharedListeners("initializeData")



 using (var fileStream = new FileStream(logFilePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))

 {.....

Using xml linq :

class Program

{

    const string FILENAME = @"c:temptest.xml";

    static void Main(string args)

    {

        XDocument doc = XDocument.Load(FILENAME);



        string change = doc.Descendants("add")

                           .Where(x => x.Attribute("initializeData") != null)

                           .Select(x => (string)x.Attribute("initializeData"))

                           .FirstOrDefault();

    }     

}
