Writing XML Into Page

I have been dealling with XML a lot lately and becasue of that I am trying to get better in it. My XML file looks like the following...

<main>
 <sec1>
  <part1>Name1</part1>
  <part2>Name2</part2>
 </sec1>
 <sec2>
  <part3>Name1</part3>
  <part4>Name2</part4>
 </sec2>
</main>

I want use ASP to write the value. I mean I want to be able to target saying sec1.part1.text will give me Name1. I can actually do it by using the following code. But I am going to have duplicate names under each section and that will creates name problems.

 Set xml = Server.CreateObject("Microsoft.XMLDOM")
 xml.async = False
 xml.load (Server.MapPath("page.xml"))

sec1 = xml.documentElement.childNodes(part1).text

Again what I want to do is

sec1 = xml.documentElement.sec1.part1.text
