에서 간단한 XML 문서를하고 난이

XmlNamespaceManager manager = new XmlNamespaceManager(xmlDoc.NameTable); 
manager.AddNamespace("rdf", "http://www.w3.org/1999/02/22-rdf-syntax-ns#"); 
manager.AddNamespace("cb", "http://centralbanks.org/cb/1.0/"); 
manager.AddNamespace("dcterms", "http://purl.org/dc/terms/"); 
manager.AddNamespace("xsi", "http://www.w3c.org/2001/XMLSchema-instance"); 
XmlNode valueNode = xmlDoc.SelectSingleNode("descendant::cb:value", manager); 
string v = valueNode.InnerText;

어떤 조언을위한

많은 감사는 다음과 같습니다

http://www.cbwiki.net/wiki/index.php/Specification_1.1

사용하는 동안 :

http://centralbanks.org/cb/1.0/

에 대한 네임 스페이스 관리자.

코드에서 네임 스페이스를 업데이트하면 문제가 해결 될 수 있습니다.
