Detailed Description
The xml_node_rss_item class is used to represent a node processing object for item elements of RSS channels.Instantiating an object of this type will register itself with the xml_text_reader_by_node object (specified in the constructor) as the handler for the item element (not item sub-elements).
This class counts items as they are encounted in an RSS feed file. If no new item (to be added to the RSS feed) is specified, then that is all this class does. If a new item is specified, that new item will be added to the feed before any existing items.
This class can thus be used for two purposes -- for counting items and for adding a new item. If it is used to add a new item and no existing items are found in the feed, that new item will not be added.
