        <ContentNode type="CustomApplicationComponent" name="Sub App Component2" url="subappcomponent2.html" tag="c2532e51-704f-45e9-abc7-f8a2a7b1f428">

推荐答案

您需要使用XMLReader来读取XML.检查以下代码.

You need to use XMLReader to read the XML. check following code.

System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(\\XML_File_path);
while(xmlReader.Read())
{
   if(XmlNodeType.Attribute)
   {
     //get AttributeName and Value
     Response.Write(xmlReader.Name.ToString()+ ": " + xmlReader.Value.ToString()));                    
    }
}

尝试

XmlNodeList elemList = doc.GetElementsByTagName(...);
   for (int i = 0; i < elemList.Count; i++)
   {
       string attrVal = elemList[i].Attributes["AttributeName"].Value;
   }

或者您也可以尝试
XmlTextReader:读取所有属性 [读取C#中的XML节点属性数据 [

or you can also try
XmlTextReader: read all attributes[^]
Read XML node attributes data in C#[^]

一种简单得多的方法:

a much simpler way:

foreach (XmlNode n1 in list)
            {
                string str = n1.Attributes["name"].Value;
            }

这个字符串 str 将具有每个节点的属性 name 的值，同样，只需给出您想要的属性的名称，我们就可以访问该值.这么简单:)

this string str will have the value of the attribute name of each node, likewise just give the name of the attribute u want and we can access the value.so simple :)
