我发现很多关于将XML保存为CSV的帖子，但我的问题是我的XML中的某些节点比其他节点的元素少。这导致我的CSV列关闭，这不是很有帮助。我正在消费的XML数据来自第三方API。
这是我的代码：
internal static void XmlToCsvFile(XmlDocument doc, string fileName)
{
var xml = new XDocument();
xml = XDocument.Parse(doc.InnerXml);
StringBuilder sb = new StringBuilder(100000);
var xmlDocForHeaders = new XmlDocument();
xmlDocForHeaders.InnerXml = xml.Root.FirstNode.ToString();
var xdocForHeaders = XDocument.Parse(xmlDocForHeaders.InnerXml);
foreach (var element in xdocForHeaders.Elements().Elements())
{
sb.Append($"{element.Name},");
}
sb.Append("\n");
foreach (XElement node in xml.Descendants("Table"))
{
foreach (XElement innerNode in node.Elements())
{
foreach (XElement elements in innerNode.Elements())
{
sb.Append($"\"{elements.Value}\",");
}
sb.Append("\n");
}
sb.Remove(sb.Length - 1, 1);
sb.AppendLine();
}
var csvOut = sb.ToString();
SaveDataToCsvFile(csvOut);
}
我知道我不需要将我的XmlDocument转换为XDocument，但当时这似乎更容易。
非常感谢任何帮助！
谢谢！

如您所见，第一条记录包含lat和long元素，但第二条记录不包含。这会在转换为CSV时抛弃所有内容。
再次感谢！

根据您的所有好评，以下是最终为我工作的内容！
internal static string XmlToCsvFile(XmlDocument doc, string fileName)
{
var xml = XDocument.Parse(doc.InnerXml);
var sb = new StringBuilder();
var record = new Dictionary<string, string>();
foreach (var element in xml.Descendants("Record").Elements())
{
if (!record.ContainsKey(element.Name.ToString()))
{
record.Add(element.Name.ToString(), "");
}
}
foreach (var key in record.Keys)
{
sb.Append($"{key},");
}
sb.Remove(sb.Length - 1, 1);
sb.AppendLine();
foreach (var node in xml.Descendants("Record"))
{
foreach (var key in record.Keys.ToList())
{
record[key] = "";
}
foreach (var elements in node.Elements())
{
record[elements.Name.ToString()] = elements.Value.ToString();
}
foreach (var value in record.Values)
{
sb.Append($"\"{value}\",");
}
sb.Remove(sb.Length - 1, 1);
sb.AppendLine();
}
var csvOut = sb.ToString();
SaveDataToCsvFile(csvOut);
return csvOut;
}
答案 0 :(得分：0)
以下是我在评论中所说的内容的快速说明。由于您似乎只是一次性执行此操作，因此您可以将XML解析为匿名类型的集合，然后遍历该集合以写出CSV。
简单示例：
var records = xml.Descedants("Record").Select(r => new
{
StoreID = (string)r.Element("StoreID"),
StoreName = (string)r.Element("StoreName"),
// other elements
};
请注意显式转换为字符串 - 如果元素丢失，这将返回null，这将解决某些记录中正常缺少某些元素的问题。否则你将不得不写一堆额外的代码来检查缺少的元素，这会非常难看。
一旦你收集了匿名类型，你就可以迭代它们来写出CSV：
foreach(var record in records)
{
// Here you can access the individual properties in the currently selected record
}
