Can Views Use an External XML Source? | Mediacurrent
Sometimes the need arises to include a list of upcoming events, recent news or job postings. The problem that sometimes occurs is the data exists on another site as an XML document. Now, you could use Feeds and periodically import those into your site as nodes and then have them set to expire (because you wouldn’t want to keep these forever). But that would take up space in your database and there’s no need for that level of complexity or trouble.
