a6e043ff AD |
1758 | * This method allows you to get access to ANY element/attribute that is a |
1759 | * sub-element of the opening feed tag. | |
1760 | * | |
1761 | * The return value is an indexed array of elements matching the given | |
1762 | * namespace and tag name. Each element has `attribs`, `data` and `child` | |
1763 | * subkeys. For `attribs` and `child`, these contain namespace subkeys. | |
1764 | * `attribs` then has one level of associative name => value data (where | |
1765 | * `value` is a string) after the namespace. `child` has tag-indexed keys | |
1766 | * after the namespace, each member of which is an indexed array matching | |
1767 | * this same format. | |
1768 | * | |
1769 | * For example: | |
1770 | * <pre> | |
1771 | * // This is probably a bad example because we already support | |
1772 | * // <media:content> natively, but it shows you how to parse through | |
1773 | * // the nodes. | |

6335 | * placeholder for audio files before they're loaded (QuickTime-only). | |
6336 | * Can be any relative or absolute URL. Defaults to blank. | |
6337 | * - `bgcolor` (string): The background color for the media, if not | |

6341 | * and it is recommended that you use this default. | |

6343 | * Defaults to `false`. | |
6344 | * - `mediaplayer` (string): The location of the included | |
6345 | * `mediaplayer.swf` file. This allows for the playback of Flash Video | |
6346 | * (`.flv`) files, and is the default handler for non-Odeo MP3's. | |

6353 | * and it is recommended that you use this default. | |
6354 | * - `widescreen` (boolean): Is the enclosure widescreen or standard? | |
6355 | * This applies only to video enclosures, and will automatically resize | |
6356 | * the content appropriately. Defaults to `false`, implying 4:3 mode. | |
6357 | * | |
