讀取多級XML並寫回單個數據庫表

Question

我是一個帶有asp.net的nube。這是我想要實現的。我想將以下XML數據寫入sql server數據庫的單個表中。

是否有人可以告訴我怎麼在我的XML文件的讀取和扁平化的數據，並將其插入到合適的表中的SQL數據庫。 在此先感謝。

Answer 1

在網上搜索，有很多關於您的要求描述的文章。試試這個：

而且

Answer 2

首先，你必須解析XML，並存儲到定製的C＃對象，或者您可以將XML直接傳遞到你的存儲過程，並做在那裏編碼保存到DB中。

將xml傳遞給存儲過程並對其進行操作有點困難，所以我建議在C＃中解析它，然後獲取自定義對象。一旦你得到它，你可以做任何你想做的事情。

這是我的文章，解釋到底你需要什麼。 Read XML file in ASP.NET(C#)

以下是解析XML文件並從中生成自定義C＃對象的示例代碼。

public CatSubCatList GenerateCategoryListFromProductFeedXML() 
{ 
    string path = System.Web.HttpContext.Current.Server.MapPath(_xmlFilePath); 

    XDocument xDoc = XDocument.Load(path); 

    XElement xElement = XElement.Parse(xDoc.ToString()); 


    List<Category> lstCategory = xElement.Elements("Product").Select(d => new Category 
    { 
     Code = Convert.ToString(d.Element("CategoryCode").Value), 
     CategoryPath = d.Element("CategoryPath").Value, 
     Name = GetCateOrSubCategory(d.Element("CategoryPath").Value, 0), // Category 
     SubCategoryName = GetCateOrSubCategory(d.Element("CategoryPath").Value, 1) // Sub Category 
    }).GroupBy(x => new { x.Code, x.SubCategoryName }).Select(x => x.First()).ToList(); 

    CatSubCatList catSubCatList = GetFinalCategoryListFromXML(lstCategory); 

    return catSubCatList; 
}
