XmlNode与XmlElement区别 转载的

//XmlNode生成XML
XmlDocument xmlnDoc = new XmlDocument();
XmlNode xmlnRoot = xmlnDoc.CreateNode(XmlNodeType.Element, "nRoot", String.Empty);
XmlNode itemNode = null;
for (int i = 0; i < 3; i++)
{
     itemNode = xmlnDoc.CreateNode(XmlNodeType.Element, "Customer", String.Empty);
     XmlNode codeNode = xmlnDoc.CreateNode(XmlNodeType.Element, "Code", String.Empty);
     codeNode.InnerText = "Code"+i.ToString();
     XmlNode nameNode = xmlnDoc.CreateNode(XmlNodeType.Element, "Name", String.Empty);
     nameNode.InnerText = "Name"+i.ToString();
     itemNode.AppendChild(codeNode);
     itemNode.AppendChild(nameNode);

     xmlnRoot.AppendChild(itemNode);
 }
xmlnDoc.AppendChild(xmlnRoot);

生成的结果为：

<nRoot>
    <Customer>
       <Code>Code0</Code>
       <Name>Name0</Name>
    </Customer>
    <Customer>
       <Code>Code1</Code>
       <Name>Name1</Name>
    </Customer>
    <Customer>
       <Code>Code2</Code>
       <Name>Name2</Name>
    </Customer>
</nRoot>

//XmlElement生成XML
XmlDocument xmleDoc = new XmlDocument();
XmlElement xmleRoot = xmleDoc.CreateElement("eRoot");
xmleDoc.AppendChild(xmleRoot);
for (int i = 0; i < 3; i++)
{
    XmlElement xmlEle = xmleDoc.CreateElement("Customer");
    xmlEle.SetAttribute("Code","Code"+i.ToString());
    xmlEle.SetAttribute("Name", "Name" + i.ToString());

    xmlEle.InnerText = "Code" + i.ToString();
    xmleRoot.AppendChild(xmlEle);
 }

生成的结果为：

<eRoot>
   <Customer Code="Code0" Name="Name0">Code0</Customer>
   <Customer Code="Code1" Name="Name1">Code1</Customer>
   <Customer Code="Code2" Name="Name2">Code2</Customer>
</eRoot>
