Question

我有一个xml文件：

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<root>
  <level>
    <node1 />
    <node2 />
    <node3 />
  </level>
</root>

在node1，node2，node3中插入值的最简单方法是什么？

Answer 1

你走了：

XmlDocument xmldoc = new XmlDocument();
xmldoc.LoadXml(@"
    <root>
        <level>
            <node1 />
            <node2 />
            <node3 />
        </level>
    </root>");
XmlElement node1 = xmldoc.SelectSingleNode("/root/level/node1") as XmlElement;
if (node1 != null)
{
    node1.InnerText = "something"; // if you want a text
    node1.SetAttribute("attr", "value"); // if you want an attribute
    node1.AppendChild(xmldoc.CreateElement("subnode1")); // if you want a subnode
}

Answer 2

//Here is the variable with which you assign a new value to the attribute
    string newValue = string.Empty 
    XmlDocument xmlDoc = new XmlDocument();

    xmlDoc.Load(xmlFile);

    XmlNode node = xmlDoc.SelectSingleNode("Root/Node/Element");
    node.Attributes[0].Value = newValue;

    xmlDoc.Save(xmlFile);

使用AppendChild方法在节点内插入子项。
