使用.NET删除带有冒号的XML节点

Question

我正在尝试删除带有冒号的XML节点，我的意思是一个名为“ saml：EncryptedAssertion”的节点。我想从saml:EncryptedAssertion删除到/saml:EncryptedAssertion

这是XML文件：

这是我已经尝试过的：

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.PreserveWhitespace = true;
xmlDoc.Load("XMLAssertionEncrypted.xml");

XmlNode product = xmlDoc.SelectSingleNode("//saml:EncryptedAssertion");

xmlDoc.RemoveChild(product);
