Question

我试图用C＃编写一个工具，该工具将接收任何XML文件（具有未定义的结构），并将生成名称和值的列表。除了XML包含其中包含标记的description节点的实例外，我基本上都能正常工作。以下面的XML示例为例：

<TESTROOT>
  <MAIN>
    <TITLE>This is a test title</TITLE>
    <VERSION>v1.0</VERSION>
  </MAIN>
  <CONTACT>
    <NAME>Some contact person</NAME>
    <ADDRESS>
      <LINE1>Address line 1</LINE1>
      <LINE2>Address line 2</LINE2>
      <TOWN>Some town here</TOWN>
      <POSTCODE>AN1 WH3</POSTCODE>
    </ADDRESS>
  </CONTACT>
  <DETAIL>
    <NOTES>
      <P>Some text may appear like this in markup tags.</P>
      <P>But is all contained within the NOTES node.</P>
      <P>These may appear in different places, not necessarily called NOTES.</P>
      <P>And may contain <a href="#">Some hyperlinks</a></P>
    </NOTES>
  </DETAIL>
</TESTROOT>

我正在使用以下代码逐步浏览上述XML，并获取节点路径和值：

public void RunMe()
{
    XmlDocument doc = new XmlDocument();
    doc.LoadXml(testxmlstring);

    // Get root node
    XmlNode root = doc.SelectSingleNode("//TESTROOT");

    // Get node info recursive
    GetNode(root, "");
}

public void GetNode(XmlNode parent, string path)
{
    foreach(XmlNode n in parent.ChildNodes)
    {
        if (n != null)
            Console.WriteLine(String.Format("{0} = {1}", path, n.Value));

        if (parent.HasChildNodes)
            GetNode(n, path + @"\" + n.Name);
    }
}

使用该示例XML和上面的代码，我得到以下输出：

\MAIN\TITLE = This is a test title
\MAIN\VERSION = v1.0
\CONTACT\NAME = Some contact person
\CONTACT\ADDRESS\LINE1 = Address line 1
\CONTACT\ADDRESS\LINE2 = Address line 2
\CONTACT\ADDRESS\TOWN = Some town here
\CONTACT\ADDRESS\POSTCODE = AN1 WH3
\DETAIL\NOTES\P = Some text may appear like this in markup tags.
\DETAIL\NOTES\P = But is all contained within the NOTES node.
\DETAIL\NOTES\P = These may appear in different places, not necessarily called NOTES.
\DETAIL\NOTES\P =     And may contain 
\DETAIL\NOTES\P\a = Some hyperlinks

如您所见，由于P标签（或其中出现的任何HTML标签），NOTES节点被分成多行。我真正想要的是这个...

\MAIN\TITLE = This is a test title
\MAIN\VERSION = v1.0
\CONTACT\NAME = Some contact person
\CONTACT\ADDRESS\LINE1 = Address line 1
\CONTACT\ADDRESS\LINE2 = Address line 2
\CONTACT\ADDRESS\TOWN = Some town here
\CONTACT\ADDRESS\POSTCODE = AN1 WH3
\DETAIL\NOTES = <P>Some text may appear like this in markup tags.</P><P>But is all contained within the NOTES node.</P><P>These may appear in different places, not necessarily called NOTES.</P><P>And may contain <a href="#">Some hyperlinks</a></P>

因此，在冗长的介绍之后，我的问题是-有没有办法获得上面显示的输出。是否可以检查标记并将节点内的所有标记作为一个值获得？

谢谢， S

我写了这个：

class Program
{
    static void Main(string[] args)
    {
        XmlMapper xmlMapper = new XmlMapper("xml.xml");
        Console.WriteLine("TEST WITHOUT BLACKLIST:\n");
        xmlMapper.PrintMap();
        Console.WriteLine("\nTEST WITH BLACKLIST:\n");
        xmlMapper.PrintMap(new List<string>() { "P" });
    }
}

class XmlMapper
{
    public string FilePath { get; private set; }
    public XDocument XDocument { get; private set; }

    public XmlMapper(string filePath)
    {
        LoadXML(filePath);
    }

    public void LoadXML(string filePath)
    {
        this.FilePath = filePath;
        this.XDocument = XDocument.Load(FilePath);
    }

    public void PrintMap(List<string> blacklist = null)
    {
        PrintElements(XDocument.Elements().ToList(), "", blacklist);
    }

    private void PrintElements(List<XElement> elements, string path, List<string> blacklist = null)
    {
        foreach (XElement element in elements)
        {
            string elementPath = path + "\\" + element.Name;

            if (blacklist != null && blacklist.Contains(element.Name.LocalName) == true)
            {
                Console.WriteLine(string.Format("{0} = {1}", elementPath, element?.ToString()));
                continue;
            }
            else
            {
                Console.WriteLine(string.Format("{0} = {1}", elementPath, element?.Value));
            }

            if (element.HasElements)
            {
                PrintElements(element.Elements().ToList(), elementPath, blacklist);
            }
        }
    }
}

输出：
