Setting a relative file reference for XmlReader
<p>Today for testing I'm using:</p>

<pre><code>XmlReader ProductDoc = XmlReader.Create(@"c:\inetpub\wwwroot\data\xml\foo\bar.xml", settings);
</code></pre>

<p>I need to make this more relative instead of a fully qualified name but can't seem to find a way to make it work.</p>

<p>I really don't have a lot of access to the web.config file and so don't want to go there.</p>

<p>Ideas?</p>
