title: Drupal 7 updating content via a service ( external source )
body: <p>I need to create a service that will receive an XML feed at any given time that will have data related to a content-type.</p>
  
  <p>Could someone please advise me what modules i should use to develop a solution.</p>
  
  <p>So</p>
  
  <p>Another server will post a xml feed with instruction add/delete/update content in the xml</p>
  
  <p>I will require to update the content type from the XML feed post</p>
  
  <p>I have previously used the migrate module but this is run on my side through cron or manual. The main difference here is that i could receive the post from the other server at any given time or possibly multiple concurrent posts.</p>
