WebDAV - Request “Show files in folder”?

Question

I want to download all *.txt files from a WebDAV share. Is there a request/methode to get a list of files from this folder?

I´m new to WebDAV and at the w3.org WebDAV methode definition I don´t found this information. http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.3
