title: Parsing parts of a Large XML File in App Engine using Blobstore?
body: <p>I'm working on an google app engine app that will have to deal with some largish ( &lt;100 MB) XML files uploaded from a form that will exceed GAE's limits -- either taking longer than 30 seconds to upload the file, or exceeding the 10 MB request size.</p>
  
  <p>The current solution I'm envisioning is to upload the file to the blobstore, and then bring it into the application (1 MB at a time) for parsing.  This could also very well exceed the 30 second limits for a request, so I'm wondering if there's a nice way to handle large XML documents in chunks, as I may end up having to do it via task queues in 30 second bursts.</p>
  
  <p>I'm currently using BeautifulSoup for other parts of the project, having switched from minidom.  Is there a way to handle data in chunks that would play nice with GAE?</p>
