title: List connection strings from external configuration file
body: <p>In my <strong>App.config</strong>, I have a reference to an external configuration file, containing connection strings for <strong>Enterprise Library</strong>:</p>
  
  <pre><code>&lt;enterpriseLibrary.ConfigurationSource selectedSource="File Configuration Source"&gt;
      &lt;sources&gt;
          &lt;add name="File Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" 
              filePath="\\path\to\my\Connections.config" /&gt;
      &lt;/sources&gt;
  &lt;/enterpriseLibrary.ConfigurationSource&gt;
  </code></pre>
  
  <p>Is there a way to list all connection strings in this file?</p>
