在 C# 中修改单个 XML 属性 [英] Modify a single XML attribute in C#

问题描述

我已经很好地编写了 XML 文档，它看起来像这样

I've got it writing the XML doc fine, and it will look something like this

<Team>
  <Character Name="Bob" Class="Mage"/>
  <Character Name="Mike" Class="Knight"/>
</Team>

我试图找到一种方法来访问单个字符的类"属性并对其进行修改.到目前为止，我已经到了可以精确定位特定字符的地步，但我不知道如何访问 'Class' 属性并为字符修改它.

I'm trying to find a way to access "Class" attribute of a single character and modify it. So far, i've got it to the point where I can pinpoint a specific character, but I can't figure out how to access the 'Class' attribute and modify it for the char.

void Write(string path, string charName, string varToChange, string value){

    XmlNode curNode = null;
    XmlDocument doc = new XmlDocument();
    doc.Load(path);

    XmlElement rootDoc = doc.DocumentElement;
    curNode = rootDoc;

    if(curNode.HasChildNodes){

        for(int i=0; i<curNode.ChildNodes.Count; i++){

            if(charName == curNode.ChildNodes[i].Attributes.GetNamedItem("Name").Value){

                // Code would go here
            }
        }
    }
    return;
}

推荐答案

使用 XPATH:

XmlDocument doc = new XmlDocument();
doc.Load(path);

var nodes = doc.SelectNodes(String.Format("/Team/Character[@Name=\"{0}\"]", charName));

foreach (XmlElement n in nodes)
{
    n.SetAttribute(varToChange, value);
}
