* Get data for an feed-level element |

|
* |
|
* The return value is an indexed array of elements matching the given |
|
* namespace and tag name. Each element has `attribs`, `data` and `child` |
|
* subkeys. For `attribs` and `child`, these contain namespace subkeys. |
|
* `attribs` then has one level of associative name => value data (where |
|
* `value` is a string) after the namespace. `child` has tag-indexed keys |
|
* after the namespace, each member of which is an indexed array matching |
|
* this same format. |
|
* |
|
* For example: |
|
* <pre> |

* // This is probably a bad example because we already support |
|
* // <media:content> natively, but it shows you how to parse through |
|
* // the nodes. |
