Question

早上好我正在尝试创建一个接受XML文件并在Raven数据库中导入所选数据的应用程序。

我有以下XML文件：这是XML代码的示例

<PHR> Hepatitis C virus (HCV) is the most common cause of liver cancer and the leading indication for liver transplantation in the United States, both of which are preventable by more effectively treating the etiologic infection. Current standard of care (SOC) for HCV treatment is inadequate for many patients and associated with significant toxic side effects. The goal of this project is to determine the relevant RNA secondary structures of a key RNA regulatory element in the HCV life cycle, which can form the basis for novel antiviral strategies directed at targeting key RNA elements.</PHR>

目前我使用以下代码查询xml文件：

string fm = "Some Text";
var names = from info in XMLFile.Descendants("row")
            where info.Element("FUNDING_MECHANISM").Value == fm
            select new {
            // much more to be added...
            SN=info.Element("SERIAL_NUMBER").Value,
            ICName=info.Element("IC_NAME").Value,
            TotalCost=info.Element("TOTAL_COST").Value };

问题是我一般希望查询从xml文件中找到所有标记名称，并动态地将它们放在SN ICName和TotalCost的位置。这是因为我想给我标记的所有名称及其旁边的值，而不仅仅是其中的一些。

我尝试了以下内容：

XMLFile.Element(Name) = fund_mech.Element(fund_mech.Name).Value

查询中的

但它不起作用。

此刻文件的输出如下：

{ SN = 1769, ICName = NCI, TotalCost = 2824 }
{ SN = 1679, ICName = NCST, TotalCost = 1191 }

但是，我希望以最佳方式检索xml文件中的更多标记。

有人可以帮忙吗？

我不知道你的最终目标是什么，但你可以使用xml来填充ExpandoObject。

来自MSDN：

“表示可以在运行时动态添加和删除其成员的对象。”

        var x = new ExpandoObject() as IDictionary<string, Object>;
        string fm = "Training, Individual";

        var names = from info in XMLFile.Elements("PROJECTS").Elements("row")
                    where info.Element("FUNDING_MECHANISM").Value == fm
                    select info;

         x = GetExpandoForNodes(names.Descendants());

         foreach (string key in x.Keys)
         {
             Console.WriteLine("Key: {0}, Value: {1}", key, x[key]);
         }
         Console.ReadKey();

下面的递归代码稍微修改了https://gist.github.com/asoftwareguy/1064812处的代码。在将元素名称保存为键之前，进行了更改以将元素名称转换为标题大小写并删除下划线。此外，如果有多个具有相同名称的子元素，则值将保存到通用的字符串列表中。

private static dynamic GetExpandoForNodes(IEnumerable<XElement> nodes)
    {            
        var config = new ExpandoObject() as IDictionary<string, Object>;
        foreach (XElement n in nodes)
        {
            if (n.Descendants().Count() == 0)
            {

                //create your property name from the xml tags, by converting to title-case and removing the underscore
                string propName = System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase(n.Name.ToString().ToLower()).Replace("_", "");

                var nodecount = from c in nodes
                                where c.Name == n.Name
                                select c;                    

                if (nodecount.Count() > 1)
                {
                    List<string> lst = new List<string>();
                    if ((config as IDictionary<String, object>).ContainsKey(propName))
                    {                            
                        lst = (List<string>)(config as IDictionary<String, object>)[propName];
                        lst.Add(n.Value.Trim());
                        (config as IDictionary<String, object>)[propName] = lst;
                    }
                    else
                    {
                        (config as IDictionary<String, object>)[propName] = new List<string>() { n.Value.Trim() };
                    }

                }
                else
                {
                    (config as IDictionary<String, object>)[propName] = n.Value.Trim();
                }              
            }
            else
            {
                dynamic child = GetExpandoForNodes(n.Descendants());                                        
            }
        }
        return config;
    }
