C# XML File to Datatable

Hi, I have an XML file like this.

<?xml version="1.0" encoding="utf-8" ?>
<rootelement>
  <titleform>
    <formname>title</formname>
    <controlname>tbxdescription</controlname>
    <visible>true</visible>
    <requiredfiled>true</requiredfiled>
  </titleform>
  <Memberform>
    <formname>member</formname>
    <controlname>tbxmemberid</controlname>
    <visible>false</visible>
    <requiredfiled>false</requiredfiled>
  </Memberform>
</rootelement>


now in C# I need output as follows. I Should be able to pass the form name through code and desired output should result in datatable. Example: If I pass formname as title, member should not appear in datatable. How do I do this ?

FormName      ControlName      RequiredField      Visible
title                     tbxtitle               true                      true
Member             tbxmemberid       false              false

            var rows = root.Elements().Select(n => n.Elements().Select(y => y.Value).ToArray());

            foreach (var row in rows)

Example: If I pass formname as title, member should not appear in datatable. How do I do this ?
i don't understand.
what do u mean u pass formname as titleform?
Refer this.

<titleform>
    <formname>title</formname>
    <controlname>tbxdescription</controlname>
    <visible>true</visible>
    <requiredfiled>true</requiredfiled>
  </titleform>

I should be able to pass title as input. Then output should be

FormName      ControlName      RequiredField      Visible
title                     tbxtitle               true                      true
so if the value of formname element is "title" then it shouldn't be included in the datatable?
If the value for formname element is "title" then "member" should not be included in datatable
If the value for formname element is "member" then "title" should not be included in datatable
sorry u gotta be more clear.
there are 2 elements in your xml: titleform and Memberform.
now please describe the use cases.
which element is not suppose to be insert to the datatable? and when?
from C# if i pass value as titleform, then output should be

FormName      ControlName      RequiredField      Visible
title                     tbxtitle               true                    true


from C# if i pass value as memberform, then output should be

FormName      ControlName      RequiredField      Visible
Member             tbxmemberid     false                 false
>>from C# if i pass value as titleform
what is that mean?
pass where?
should be something like

var root = XElement.Load(@"c:\temp\1.xml\title");

I mean pass to XML
U cant pass variable to xml like this.
U can have a function which accept either title or member, and the function will populate datatable accordingly.
What i failed to understand is what should the results.
Result is here

from C# if i pass value as titleform, then output should be

FormName      ControlName      RequiredField      Visible
title                     tbxtitle               true                    true


from C# if i pass value as memberform, then output should be

FormName      ControlName      RequiredField      Visible
Member             tbxmemberid     false                 false
