Get a Directory Listing as XML

Demonstrates the Chilkat Ftp2.GetXmlDirListing method, which retrieves a directory listing and returns the parsed entries as an XML document rooted at <remoteDir>, with a <file> element per entry. The only argument is the listing pattern; an empty string lists the current directory.

Tip: Code to parse the returned XML can be generated at Chilkat Tools.

Background: This is the parse-friendly listing: Chilkat has already interpreted the server's raw LIST output — whatever its format — into consistent XML with names, sizes, dates, and types as elements. That spares you from writing format-specific parsers and is the right choice when a program, rather than a person, consumes the listing. Load the result into a Chilkat.Xml object to iterate the entries.
