At work we are going to be receiving XML files from a supplier via FTP (Push to our server) I need to think about best practice here...

I need this received XML file to be accessible to remote databases in order to pull into filemaker.

I was thinking about applescripting a remote mac to pull down the xml then instruct FileMaker to import it but I'm still a little unsure of the exact/best process to do this.

You might be able to do it all from within Filemaker:

I think the SmartPill php plugin has some ftp functions and does a number of other things:

You can also look at the ftpit plugin:
