Question

I have a xml as below:

<?xml version="1.0" encoding="ISO-8859-1"?>
<TestCase Name="1.7 Bus01">
 <Action Word="Login" Text="Login" TestCaseId="MPD_QS_06">
    <Parameter Name="userName" Value="user1"/>
    <Parameter Name="userPwd" Value="user1"/>
    <Parameter Name="Tenant" Value="tnt1"/>
    <Parameter Name="expectedResult" Value="Login success"/>
 </Action>
 <Action Word="AddOrganisation" Text="AddOrganisation">
    <Parameter Name="name" Value="MAHNEWX"/>
    <Parameter Name="senderId" Value=""/>
    <Parameter Name="address" Value="77 Westferry Circus"/>
    <Parameter Name="postCode" Value="E77 4 HB"/>
    <Parameter Name="city" Value="London"/>
    <Parameter Name="country" Value="United Kingdom"/>
    <Parameter Name="state" Value=""/>
    <Parameter Name="email" Value=""/>
    <Parameter Name="telCountryCode" Value=""/>
    <Parameter Name="telNumber" Value=""/>
    <Parameter Name="telExtension" Value=""/>
    <Parameter Name="faxCountryCode" Value=""/>
    <Parameter Name="faxNumber" Value=""/>
    <Parameter Name="faxExtension" Value=""/>
    <Parameter Name="roleList" Value="MAH"/>
    <Parameter Name="expectedResult" Value="Organisation is added"/>
  </Action>
  <Action Word="NewValidationRegistration" Text="NewValidationRegistration">
    <Parameter Name="registrationname" Value="FusionUnion"/>
    <Parameter Name="AS2Identifier" Value="MPTVC"/>
    <Parameter Name="expectedResult" Value="Registration is validated"/>
  </Action>
  <Action Word="NewSubmissionRegistration" Text="NewSubmissionRegistration">
     <Parameter Name="registrationname" Value="FusionUnion"/>
     <Parameter Name="AS2Identifier" Value="MPTVC"/>
     <Parameter Name="expectedResult" Value="Registration is submitted"/>
  </Action>
  <Action Word="Logout" Text="Logout">
     <Parameter Name="expectedResult" Value="Logout success"/>
  </Action>
</TestCase> 

For each Action Word I have a method. How can I read this xml and execute the methods dynamically with parameters. The Parameter Name s are actual variables in my methods. The number of parameters differs each time. Precisely, I want to read the xml and get the list of action words and then execute them using the values.
Thanks for ur help in advance.

object obj = this; //your object containing methods
XDocument xDoc = XDocument.Parse(xml);
Type type = obj.GetType(); 

foreach (var action in xDoc.Descendants("Action"))
{
    MethodInfo mi = type.GetMethod(action.Attribute("Word").Value);

    var dict =  action.Descendants().ToDictionary(
                                         d=>d.Attribute("Name").Value,
                                         d=>d.Attribute("Value").Value);

    object[] parameters = mi.GetParameters()
        .Select(p => Convert.ChangeType(dict[p.Name],p.ParameterType))
        .ToArray();

    var expectedResult = mi.Invoke(obj, parameters);

    Debug.Assert(expectedResult.Equals(dict["expectedResult"]));
}
