Parsing RSS Feeds by XmlListModel
It's true that we now have categories, but they don't seem to be involved with RSS at all. Also, if you dig deeper, you'll find that the RSS feeds are in fact the XML documents. Qt already provides a useful type to help us parse them. We don't need to reinvent the wheel. This powerful type is the so-called
