Creating a program to fill in a template?

[Jimmy422]

I want to create a program that will fill in a template of an xml file and then save that template as a completed .xml file. What language would be good to do something like this in? And how would I go about doing it?

Here's a mockup of what i'm looking to make:

Which would, for example, correspond to the following snippet of code in the XML file:

  <header watermarkAlign="SET_ALIGNMENT" backgroundColor="#SET_BACKGROUND_COLOR" textColor="#SET_TEXT_COLOR">

  </header>

Is this even possible?

Writing is easier done than said. It's possible.

Create a .xml file and output the string?

VB for the easy GUI (and if not, then C#).

Write to file:

"<header watermarkAlign='" + alignmentVar + "' backgroundColor='" + backgroundcolorvar + "' textColor='" +colorvar + "'></header>"

I'm not huge on coding, could you give me an example of how to edit the file after inputting the value by a radio button or whatever it may be?
