Here is an example:
	<status>200</status>
	<requestId>yyy-zzz-aaa</requestId>
	<photos>
	  <twitter>
	    <typeName>Twitter</typeName>
	    <url>http://example.com</url>
	   </twitter>
	</photos>
	 
	For example, you can then reference photos.twitter[0].url as the Response Attribute and then map that to any Marketo field. Let me know if that makes sense?
