FTP XML Directory Listing / Download Most Recently Modified Files

Demonstrates how to retrieve a directory listing in XML format, sort it by last-modified date, and download the 5 most recently modified files.

Note: This example relies upon a new feature added to the GetXmlDirListing method. Namely, the resultant XML includes a "full" attribute with a date/time that is in a sortable format. This feature is available in the pre-release, or in new versions released after 20-May-2008.
