1757 |
* This method allows you to get access to ANY element/attribute that is a
|
1758 |
* sub-element of the opening feed tag.
|
1759 |
*
|
1760 |
* The return value is an indexed array of elements matching the given
|
1761 |
* namespace and tag name. Each element has `attribs`, `data` and `child`
|
1762 |
* subkeys. For `attribs` and `child`, these contain namespace subkeys.
|
1763 |
* `attribs` then has one level of associative name => value data (where
|
1764 |
* `value` is a string) after the namespace. `child` has tag-indexed keys
|
1765 |
* after the namespace, each member of which is an indexed array matching
|
1766 |
* this same format.
|
1767 |
*
|
1768 |
* For example:
|
1769 |
* <pre>
|
1770 |
* // This is probably a bad example because we already support
|
1771 |
* // <media:content> natively, but it shows you how to parse through

1772 |
* // the nodes.
