我試圖解析rss提要。我可以得到的元素,但無論我嘗試,我無法獲得屬性!使用XDocument和LINQ讀取屬性
這是RSS提要(XML)的樣子:
<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">

我想要得到的屬性是 '圈地URL'。
這是我的嘗試:
private IEnumerable<Channel> getChannelQuery(XDocument xdoc)
{
return from channels in xdoc.Descendants("channel")
select new Channel
{
Title = channels.Element("title") != null ? channels.Element("title").Value : "",
Link = channels.Element("link") != null ? channels.Element("link").Value : "",
Description = channels.Element("description") != null ? channels.Element("description").Value : "",
//PubDate = channels.Element("pubDate") != null ? channels.Element("pubDate").Value : "",
//Enclosure = channels.Element("enclosure ") != null ? channels.Element("enclosure").Value : "",
Items = from items in channels.Descendants("item")
select new Item
{
Title = items.Element("title") != null ? items.Element("title").Value : "",
Link = items.Element("link") != null ? items.Element("link").Value : "",
Description = items.Element("description") != null ? items.Element("description").Value : "",
Guid = (items.Element("guid") != null ? items.Element("guid").Value : ""),
PubDate = (items.Element("pubDate") != null ? items.Element("pubDate").Value : ""),
Enclosure = (items.Attribute("url") != null ? items.Attribute("url").Value : "")
}
};
}
什麼我錯在這裏做什麼?
你是怎麼做到的? – Yustme 2010-10-16 11:26:29
