title: Boto MWS Python Response issue
body: <p>I am trying to use <a href="http://boto.readthedocs.org/en/latest/ref/mws.html" rel="nofollow noreferrer">Boto</a> to read an Amazon MWS Response to get matching products for ID. I have my connection working fine, and am able to get results, but having issues trying to parse the results.  It looks like Boto has built in results parsers such as <code>Response</code> and <code>ResponseFactory</code>. I just can't figure out how to transfer the information to these method so I can implement some of the pre built code.</p>
  
  <p>This code:</p>
  
  <pre><code>mws = MWSConnection(accessKeyId,secretKey,Merchant=merchantId)
  response = mws.list_matching_products(MarketplaceId=marketplaceId,Query="Beanie Babies")
  </code></pre>
  
  <p>prints out this string:</p>

  <p>I'm sure I can figure out how to parse the XML using an XML parser, but it seems like <code>Response</code> and <code>ResponseFactory</code> would make life much easier for me. I can't find any real world examples on line to copy and play with, and as I have no programming background I don't fully understand all the documentation properly.  Any help would be greatly appreciated.</p>
