我的XML是的XPath與元素結腸元素名稱

我想改變地址元素值
XmlDocument fedMetaDocument = new XmlDocument();
fedMetaDocument.Load(federatedMetadataFile);
XmlNamespaceManager mgr = new XmlNamespaceManager(fedMetaDocument.NameTable);
mgr.AddNamespace("fed", "http://docs.oasis-open.org/wsfed/federation/200706");
foreach (XmlNode targetScopeNode in fedMetaDocument.SelectNodes("TargetScopes/EndpointReference/Address", mgr))
{
targetScopeNode.Value = tsakListUrl;
}
foreach (XmlNode PassiveRequestorEndpointNode in fedMetaDocument.SelectNodes("TargetScopes/EndpointReference/Address", mgr))
{
PassiveRequestorEndpointNode.Value = tsakListUrl;
}
我得到一個錯誤
