Update the xml database using C#
<p>I have created a login form and the login details like username and password gets stored in xml database.</p>

<p>Now when a particular user wants to change his/her password. how to do that using xml database in C#. I don't have much idea on xml database. please help me out at the earliest.</p>

<p>Change password form looks like this </p>

<pre><code>User name : 
Old password:
new password:
Confirm password:

Change(button)
</code></pre>

<p>when the user provides the necessary information and clicks the change button. the old password which gets stored in xml database should get replaced by the new password..</p>
