使用C＃，我们如何从XML Schema文件中提取属性值并将其输出到CSV文件？

Question

我正在尝试获取此XM1架构文件（以下XML）中每个元素的属性值。我需要以下属性值：类型，标签，CompType，只读，隐藏和必需。

例如，这是XML文件中的元素之一：

<element type="xpowercomponent_FeaturedTiles" UID="40204fc9b5424b349e03134d777d29bc" label="Featured Tiles" readonly="false" hidden="false" default="" required="false" Component="" CompTypes="ThemedTileSetComponent;ThemedTileSetElectedComponent;" AutoEmbed="" WrappedUp="" AllowWrappingChange="" />

此元素的预期结果应该是：

xpowercomponent_FeaturedTiles，精选图块，ThemedTileSetComponent，ThemedTileSetElectedComponent，readonly =“ false”，hidden =“ false”，需要= “假”

我已经启动了C＃应用程序以获取此信息，但是它无法正确获取所有信息。您能否看一下代码，看看如何解决或改进它？有没有更好的方法来解决这个问题，也许是LINQ？最终目标是将这些属性值/数据输出到CSV文件中。

C＃

{
    static void Main(string[] args)
    {
        Parse();
    }

        xmlDoc.Load(@"D:\New Text Document.xml");

        var captureElements = new List<CustomElements>();


        var xdocument = xmlDoc.ToXDocument();
        foreach (var element in xdocument.Elements())
        {
            foreach (var node in element.Elements()) //childs...
            {

                if (node.Name.LocalName.Equals("ElementType"))
                {
                    foreach (var scopeNode in node.Elements())
                    {
                        if (scopeNode.Name.LocalName.Equals("element"))

Answer 1

您可以使用System.Xml.Linq来获取所有元素和所需的属性，如下所示

        XDocument document = XDocument.Load(@"D:\New Text Document.xml");
        var eleCollection = document.Elements("element");

        foreach (var element in eleCollection)
        {
            var type = element.Attribute("Type").Value;
        }
