xml中怎么添加noNamespaceSchemaLocation和xsi

[阿尔萨斯djw]

<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-
envelope.xsd">

XmlDocument xmldoc = new XmlDocument();
XmlElement xmlelem;
XmlElement data;
xmlelem = xmldoc.CreateElement("", "AmazonEnvelope", "");
//xmlelem.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
//xmlelem.SetAttribute("xsi","noNamespaceSchemaLocation", "amzn-envelope.xsd");
XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
XAttribute att = new XAttribute(xsi + "noNamespaceSchemaLocation", "amzn-envelope.xsd") ;

我直接用setAttribute不行
网上有一个用XDocument的但是我用的是XmlDocument，不想改了

参考: Creating attributes for root element

 XmlDocument doc = new XmlDocument();
            XmlElement root = doc.CreateElement("AmazonEnvelope");
            root.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
            root.SetAttribute("noNamespaceSchemaLocation", "http://www.w3.org/2001/XMLSchema-instance", "amzn-envelope.xsd");
            doc.AppendChild(root);
            doc.Save("TestEE.xml");

这样的结果是<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" noNamespaceSchemaLocation="amzn-envelope.xsd"> 不是我想要的 <AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn- envelope.xsd">

请问楼主 你这个问题处理了吗？ 我也遇到了。 如果有方法了 麻烦告知下！！谢谢

[SowLuo]

我已经找到方法了。。。顺便也告诉你下

// 首先要创建一个空的XML文档 ，然后在其中加入元素
                    XmlDocument doc = new XmlDocument();
                    XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
                    XmlAttribute xsispace = doc.CreateAttribute("xsi", "noNamespaceSchemaLocation", "http://www.w3.org/2001/XMLSchema-instance");
                    xsispace.Value = "Schema-3.0.xsd";
                    XmlAttribute xsi = doc.CreateAttribute("xmlns:xsi");
                    xsi.Value = "http://www.w3.org/2001/XMLSchema-instance";

                    doc.AppendChild(dec);
                    //创建一个根节点（Document）
                    XmlElement Document = doc.CreateElement("Document");
                    Document.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
                    Document.Attributes.Append(xsi);
                    Document.Attributes.Append(xsispace); 
                    Document.SetAttribute("SN", "323232323");
                    Document.SetAttribute("Version", "3.0");
                    Document.SetAttribute("License", "00120-100290-002");
                    doc.AppendChild(Document);
