将包含重复标记的XML文件转换为CSV

Question

我正在寻找一种方法，将XML文件转换为CSV文件，并将标记名称作为标题。但是，我的问题是XML文件有一些重复的标签，所以它使解析文件的过程和＆＃34;发现＆＃34;元素很难。我的问题出在<File>标签上。

这是我尝试转换的文件的片段。另外，请注意<File>标记是动态的，因此它可以包含0个甚至10个<File>标记。

我有一个将其转换为CSV的解决方案，但它不会处理重复的标记。它只是继续使用第一个<File>标记的详细信息。因此，在我的CSV文件中会有3个文件的标签，但它们都会有第一个标签的详细信息。

var xml = XDocument.Load(@"C:/path/7123451_53957.xml");
string program = "Program";

Func<XDocument, IEnumerable<string>> getFields =
    xd =>
        xd
            .Descendants(program)
            .SelectMany(d => d.Descendants())
            .Select(e => e.Name.ToString());

var headers =
    String.Join(",",
        getFields(xml)
            .Select(f => csvFormat(f)));

var programQuery =
    (from programs in xml.Descendants(program)
        select string.Join(",",
            getFields(xml)
        .Select(f => programs.Descendants(f).Any()
            ? programs.Descendants(f).First().Value
            : "")
        .Select(x => csvFormat(x))))
    .ToList();

我认为问题出在programs.Descendants(f).First().Value部分。
