Editing xml file ;swapping nodes

[KUTTAN]

I have an xml file as follows

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

<Nodes>

<Nodes1>

<siteMapNode title="Product Cataloge">

<siteMapNode title="ManagePr oducts" url="~/Admin/Products.aspx" />

<siteMapNode title="ManageCa tegory" url="~/Admin/Category.aspx"/>

</siteMapNode>

</Nodes1>

<Nodes2>

<siteMapNode title="Orders">

<siteMapNode title="RFQ" url="~/Admin/ManageQut.aspx" />

<siteMapNode title="Orders" url="~/Admin/ManageOrder.asp x" />

</siteMapNode>

</Nodes2>

</Nodes>



See the above shows one of my xml file in my application

I am using them to populate data in a tree(no problem)



Now in this xml file for example

ManageProducts is the first item under Product Cataloge

But I want to change it in a server side event

I want to make

ManageCategory as the first item under Product Cataloge and

ManageProducts as the second item under Product Cataloge



Ie I want two swap nodes in a xml file

What is the best way to do this
