title: Update xml's with script and wp all import
body: <p>We are using 5 xml files for
  1.amounts.xml
  2.barcodes.xml
  3.features2.xml
  4.data.xml
  5.prices_ba.xml
  all of them updated with cronjobs on server and fetching URL of the xml it self.
  We receive 5 different xml files from the supplier. The problem is that when the xml is called it uses server resources. Is there a way to automatically save it to the server and have cronjobs calling this file for updates?</p>
