Is there any way of getting a list/array of XML files from a server?

There will be a folder sat somewhere on the internet that will house multiple XML files. I want to be able to point to the URL and scrape all the XML files from it for parsing.

I had a look at the WWW class and from what I can tell you can only grab one thing at a time? And I want to do all this in WebGL.

I’d appreciate any help at all!

If you wish to run multiple downloads at same time you would need to use threading.

You can run several downloading coroutines in parallel just fine without messing with threads yourself.
Finding all files in a folder on some web address is not possible from the client. You must supply the list of files from the server. Simply downloading another file that contains a list of all the addresses to the other files should do the trick.
