XML as datasource

[Andy]

I'm just starting to really get into xml these days. I have written a utility that will email out notifications of an event. I want to have an external list of 'subscribed' users that I can manipulate without having to re-compile everytime someone is added or deleted from the 'list'.

I figure xml is the easiest way to go. Here is what I have so far but I can't figure out how to read the nodes and create a semi-colon delimited string out of them.

<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns="http://tempuri.org/App.xsd">
    <user>[email protected]</user>
    <user>[email protected]</user>
    <user>[email protected]</user>
    <user>[email protected]</user>
</configuration>

I've looked into the xmlTextReader class and some others but i'm thoroughly confused on the subject. What advice can someone give me here?
