我能够将自己的标记添加到RSS源(通过阅读this question中的答案),但现在我似乎无法在代码中访问该标记。
我尝试修改现有的示例Feed(this one),只添加一个标记,如下所示。
<?xml version="1.0"?>
<rss version="2.0" xmlns:my="http://tempuri.org">
<channel>
<title>Liftoff News</title>
<link>http://liftoff.msfc.nasa.gov/</link>

<my:br_id>1507</my:br_id>
</item>
</channel>
</rss>
在代码中我有这个类:
public class SimpleSyndicationItem
{
public DateTimeOffset Date { get; set; }
public string Title { get; set; }
public Uri Link { get; set; }
public string Id{ get; set; }
public SimpleSyndicationItem(DateTimeOffset date, string title, Uri link, string id)
{
Date = date;
Title = title;
Link = link;
Id = id;
}
}
Id属性应该在my:br_id中接收值,现在,在阅读过程中我有这个:
var RssItems = new ObservableCollection<SimpleSyndicationItem>();
var reader = XmlReader.Create("rssexample.xml");
var feed = SyndicationFeed.Load(reader);
foreach(var item in feed.Items)
{
//This is the part where I want to access the tag's value, notice the ??
RssItems.Add(new SimpleSyndicationItem(item.PublishDate, item.Title.text,
item.Links[0].Uri, item.??));
}
至少intellisense没有显示br_id,所以我想知道在代码中访问此标记的正确方法是什么。
答案 0 :(得分:1)
item.ElementExtensions[0]
怎么样?
