The feed we are loading is this : http://www.tfl.gov.uk/tfl/syndication/feeds/cycle-hire/livecyclehireupdates.xml – It updates once every 3 mins.\r\n\r\nIf the data is loaded as the app boots, that causes a lot of instant crashes.\r\n\r\nWhen it does fail, the feed is still valid.\r\n\r\n\r\nI have attached two log files, one where it crashed, and one where it works, but some of the nodes fail to parse.\r\n\r\nIn the Failed to Parse in Loop file, the two points of interest are: (our errors)\r\n\r\n\r\n[INFO] about to convert XML node to JS node number 6\r\n[INFO] about to convert XML node to JS node number 7\r\n[INFO] about to convert XML node to JS node number 8\r\n{color:red} [ERROR] Retreiving Node name lat failed on XML object.
