XML 节点的格式不熟悉

本文关键字：不熟悉 格式 节点 XML | 更新日期: 2023-09-27 18:17:18

我正在尝试从我的 C# 代码访问由第三方设置的这个 xml。 我可以使用定义良好的节点访问 XML，它们如何进行 XML 设置对我来说并不熟悉。 有没有办法把这些数据拿出来？

下面是一个我不熟悉的 XML 示例。 谢谢。

XML 节点的格式不熟悉

它们是属性： 使用 Linq2Xml，您可以轻松解析它。

var xDoc = XDocument.Load(filename);
var result = xDoc.Descendants("HOTSPOT")
                .Select(h => new
                {
                    Name = (string)h.Attribute("NAME"),
                    Media = (string)h.Attribute("MEDIA"),
                    X = (int)h.Attribute("X"),
                    // .......
                })
                .ToList();

这些是属性值。 使用"@"进行查询，如下所示：

XmlDocument xdoc = new XmlDocument();
xdoc.LoadXml(text);
Console.WriteLine(xdoc.SelectSingleNode("/DATA/HOTSPOTSETUP/@LISTTITLE").Value);

你可以做这样的事情：

        XmlDocument doc = new XmlDocument();
        try { doc.Load("c:''temp''test.xml"); }
        catch (Exception ex) { }
        XmlElement root = doc.DocumentElement;
        foreach (XmlNode node in root.SelectNodes("/DATA"))  //could eliminate this outer loop if only one "DATA" block exists (adjust the other XPath to compensate)
        {
            foreach (XmlNode child in node.ChildNodes)
            {
                String attrValue = child.Attributes["XSCALE"].Value;
            }
        }

foreach (XmlElement hotspot in doc.SelectNodes("//HOTSPOT"))
{
    foreach (XmlAttribute attribute in hotspot.Attributes)
        Console.WriteLine("{0}={1}", attribute.Name, attribute.Value);
    Console.WriteLine("");
}

顺便说一句，如果您寻找 XPath 教程，您会发现您的任务更容易。

XML 文件看起来很好。使用 LINQ to SQL 读取它

string Path = "YourURLorFileLocation";
XDocument doc = XDocument.Load(Path);
//To read the HOTSPOT elements
var HotSpotElements = doc.Element("DATA").Elements("HOTSPOT");
//OR you can use
//var HotSpotElements = doc.Descendants("HOTSPOT")
//Element(s) looks at immediate child while Descendants look at all children
foreach (var element in HotSpotElements)
{
    //This is how you will read the attributes
    var ID = element.Attribute("ID").Value;                    
}

XmlDocument doc = new XmlDocument();
    doc.Load(Server.MapPath("~/hotspots.xml"));
    XmlNode root = doc.DocumentElement;
    XmlNodeList nodeList = root.SelectNodes("HOTSPOT");
    foreach (XmlNode node in nodeList)
    {
        XmlNode idNode = node.SelectSingleNode("@ID");
        //nodeText = node.SelectSingleNode("ID").ToString();
        if(idNode != null)
        {
            ddlXml.Items.Add("Item - " + idNode.InnerText);
        }
    }
