c# - 如何在C#中显示元素子节点的属性值？

Question

我应该如何显示元素的子节点属性中包含的值？请考虑以下示例：

 <?xml version="1.0" encoding="utf-8"?>
    <Segments>
        <Segment ID="AAA">
            <Elements>

                <Element ID ="11" />

                <Element ID ="22" El/>

                <Element ID ="33" />
            </Elements>
         </Segment>
    </Segments>    

C# 代码

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(MyXMLFileLocation);

XmlNodeList xnList = xmlDocument.SelectNodes(/Segments/Segment[@ID='AAA']/Elements);
foreach (XmlNode xn in xnList)
{
    if (xn.HasChildNodes)
    {
        foreach (XmlNode childNode in xn.ChildNodes)
        {

            // How should I fetch the attributes of childnodes here. I have to show the value contained in ID attributes
         }
    }  
}

Answer 1

尝试childNode.Attributes["ID"].Value;这样你就可以获得它的价值。

Answer 2

尝试这个：

XmlDocument xmlDocument = new XmlDocument();
    xmlDocument.LoadXml(xml);

    XmlNodeList xnList = xmlDocument.SelectNodes("/Segments/Segment[@ID='AAA']/Elements");
    foreach (XmlNode xn in xnList)
    {
        if (xn.HasChildNodes)
        {
            foreach (XmlNode childNode in xn.ChildNodes)
            {
                string id = childNode.Attributes["ID"].Value;
            }
        }
    }
