Get FTP Filenames as XML (NLST)

Demonstrates the Chilkat Ftp2.NlstXml method, which sends NLST and returns the matching names in XML form. The only argument is appended literally; an empty string sends a bare NLST and a value like *.txt sends NLST *.txt.

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

Background: NLST is the lightweight listing command: it returns only names, with none of the sizes, dates, or type information that LIST provides. That makes it fast and simple when a bare list of filenames is all you need — for example to drive a batch of downloads. Wrapping the result as XML gives you a clean, uniform structure to iterate regardless of how the server formats the raw NLST reply.
