我有一个文档如下：

<title>How I really feel about Cheese</title>
<description><p>
I was asked in a comment why I reallydo
n't like cheese...</description>
</item>
</rdf:RDF>
但我在使用
SelectSingleNode("//channel"
的时候，其结果都是空，访问其它节点SelectSingleNode("//title",SelectSingleNode("//rdf:RDF/channle/title"也都是返回NULL，我看到有文章介绍在.Net里面可以通过nsMgr = new XmlNamespaceManager(feedXml.NameTable);
nsMgr.AddNamespace("rdf", "http://www.w3.org/1999/02/22-rdf-syntax-ns#"
nsMgr.AddNamespace("dc", "http://purl.org/dc/elements/1.1/"
nsMgr.AddNamespace("rss", "http://purl.org/rss/1.0/"
来实现，但我Javascript里面怎么处理呢？MSXML根本就没有XmlNamespaceManager这个接口
