怎么读取RSS RDF中的dc:date数据

Question

例如
http://www.syokenshimpo.co.jp/rss/summary_kokunai.rdf#
在这个网页中能读到description,但是读不到dc:dateXmlNamespaceManager nsMgr = new XmlNamespaceManager(xml.NameTable);
nsMgr.AddNamespace("rdf", "http://www.w3.org/1999/02/22-rdf-syntax-ns#");
nsMgr.AddNamespace("rss", "http://purl.org/rss/1.0/"); 
XmlNodeList nodes = xml.SelectNodes("/rdf:RDF/rss:item", nsMgr);
_description = nodes[c].SelectSingleNode("rss:description",nsMgr).InnerText.Replace("<p>","");//正确
d_description = nodes[c].SelectSingleNode("rss:dc:date",nsMgr).InnerText.Replace("<p>","");//错误
d_description = nodes[c].SelectSingleNode("dc:date",nsMgr).InnerText.Replace("<p>","");//错误
d_description = nodes[c].SelectSingleNode("rss:date",nsMgr).InnerText.Replace("<p>","");//错误
d_description = nodes[c].SelectSingleNode("date",nsMgr).InnerText.Replace("<p>","");//错误
请问应该怎么读dc:date这个标签.

nsMgr.AddNamespace("dc", "http://purl.org/dc/elements/1.1/");
d_description = nodes[c].SelectSingleNode("dc:date",nsMgr).InnerText.Replace("<p>","");
