1815 * Get data for an feed-level element |
|
1816 * |
|
1817 * This method allows you to get access to ANY element/attribute that is a |
|
1818 * sub-element of the opening feed tag. |
|
1819 * |
|
1820 * The return value is an indexed array of elements matching the given |
|
1821 * namespace and tag name. Each element has `attribs`, `data` and `child` |
|
1822 * subkeys. For `attribs` and `child`, these contain namespace subkeys. |
|
1823 * `attribs` then has one level of associative name => value data (where |
|
1824 * `value` is a string) after the namespace. `child` has tag-indexed keys |
|
1825 * after the namespace, each member of which is an indexed array matching |
|
1826 * this same format. |
|
1827 * |
|
1828 * For example: |
|
1829 * <pre> |
|
1830 * // This is probably a bad example because we already support |
|
1831 * // <media:content> natively, but it shows you how to parse through |
|
1832 * // the nodes. |
|
1833 * $group = $item->get_item_tags(SIMPLEPIE_NAMESPACE_MEDIARSS, 'group'); |
|
1834 * $content = $group[0]['child'][SIMPLEPIE_NAMESPACE_MEDIARSS]['content']; |
|
1835 * $file = $content[0]['attribs']['']['url']; |
|
1836 * echo $file; |
|
1837 * </pre> |
