Hi All,
My config file structure is like below
<pre class="prettyprint lang-vb <configuration>
<Applications>
<ApplicationName>App1</ApplicationName>
<ApplicationName>App2</ApplicationName>
<ApplicationName>App3</ApplicationName>
/Applications>
</configuration>[/code]
I want to remove the all child nodes(ApplicationName) from this parentnode(Applications)
I have tried most of the common methodology but still not able to get success.
Can anyone help me on this ?
