從dtd或xsd甚至xml文檔本身的NHibernate映射

我已經搜索和搜索，但找不到任何東西，甚至遠程類似於答案。從dtd或xsd甚至xml文檔本身的NHibernate映射

我有一個XML文檔類型（我的文檔類型，沒有NHibernate相關）的DTD（xml-dtd），我想將給定文檔類型的所有文檔存儲到關係模型中。不，我不想將XML文件本身作爲某種varchar或XML字段或某種類型存儲到數據庫中，這會破壞目的 - 我希望將其分解爲其元素和屬性，並將其存儲爲THAT，作爲一個適當的關係模型。而XML支持。

我可以在Visual Studio 2015中從給定的DTD創建XSD，然後使用該XSD創建反映給定XSD（以及擴展原始DTD）的C＃類。文件解析，一切都OK。

現在的問題是如何通過NHibernate將這些XML文檔存儲到RDBMS中，而無需（大量）手工編碼，從而所有關係都以這種方式存在？通過使用自動映射功能必須有一個簡單的方法，但是原來的DTD（一些IDREF的東西等關係的東西）存在一些「侷限性」，我想將它們「轉換」爲關係並且具有適當的與其他類的關係，而不是將「code」存儲爲字符串類型的值。

所以基本上，我需要一個NHibernate的& & XML & & DTD & & XSD大師在同一時間，以闡明如何可以很容易地取得了一些光。至少在過去的10 - 15年裏，我確信這種事情與hibernate和nhibernate是「正常的」（我從未嘗試過，似乎是我第一次需要將XML文檔存儲在數據庫中）到他們的組成部分而不是整體）。

如果這樣的事情是不可能的，那麼是否還有NHibernate的「XML文檔驅動程序」這樣的事情，以便它不必進入RDBMS，而是保留爲文件系統上的XML文檔？（例如，SGML/XML專家在那裏查看IDREF和NMTOKEN，他們爲什麼只是「字符串」，而不是他們應該去的地方的適當關係，即另一個類或用法或變體或其他什麼？）：最終結果是：

我期望的參考是「類」與「代碼」（或ID）G117本身（如public virtual Class Reference { get; set; }

實際結果：只是一個字符串「代碼」與價值「G117 「如在

中

[System.Xml.Serialization.XmlAttributeAttribute(DataType="NMTOKEN")] 
    public string code { 
     get { 
      return this.codeField; 
     } 
     set { 
      this.codeField = value; 
     } 
    }

XML文件：

<Class code="G117" kind="process"> 
    <SuperClass code="G"/> 
    <Rubric id="13-223" kind="preferred"> 
     <Label xml:lang="en">A preferred label</Label> 
    </Rubric> 
    <Rubric id="13-224" kind="shortTitle"> 
     <Label xml:lang="en">Short title</Label> 
    </Rubric> 
    <Rubric id="13-225" kind="exclusion"> 
     <Label xml:lang="en">There is some exclusion text with a reference here <Reference>G12</Reference></Label> 
    </Rubric> 
    <Rubric id="13-226" kind="criteria"> 
     <Label xml:lang="en">Some criteria text goes here</Label> 
    </Rubric> 
</Class> 

<Rubric id="56-327" kind="exclusion"> 
    <Label xml:lang="en">This is some thext that might refer someplace <Reference>G117</Reference>; and another piece of text that refers to another place <Reference>BF9</Reference>; Another text describing something and there might be a reference from this piece of text somewhere else too <Reference>AB7</Reference></Label> 
</Rubric>

DTD：

<!ELEMENT Class (Meta*,SuperClass*,SubClass*,ModifiedBy*,ExcludeModifier*,Rubric*,History*)> 
<!ATTLIST Class code NMTOKEN #REQUIRED kind IDREF #REQUIRED usage IDREF #IMPLIED variants IDREFS #IMPLIED> 
<!ELEMENT Rubric (Label+,History*)>

那麼，奧斯卡，和其他誰可能對這樣的事情感興趣，它花了我12天，但最終我弄明白了，它的工作原理。它需要幾秒鐘（也許2）來創建映射，數據庫，並用XML中的數據填充它，但它然後運行得非常好。仍然不確定如何將「IDREF」類型映射到真實ID，但這與我在過去幾天的經歷相比，是一個小問題。

我很困惑 - 看來你是矛盾的你自己。有一次，你聲明「如何通過NHibernate將這些XML文檔存儲到RDBMS中？「然後稍後問你」是否還有像NHibernate的「XML文檔驅動程序」這樣的東西，以便它不必進入RDBMS，而是作爲文檔系統上的XML文檔？「這看起來像確切與第一個問題相反

在任何情況下--NHibernate是一個用於映射對象模型和可以使用SQL查詢的各種關係數據庫系統的框架如果您發現一個使用XML文件存儲數據和暴露的RDBMS這些文件的SQL外觀，也許你可以爲它編寫一個NHibernate驅動程序，但是NHibernate本身並不包含像定位XML文件的查詢引擎之類的任何東西。至於映射到NHibernate的RDBMS，我懷疑你的最好的辦法是寫一些產生的東西NHibernate的映射配置。通過轉換爲NHibernate的XML配置，或者通過發佈代碼映射或FluentNHibernate。

我忘了說「萬一這樣的事情是不可能的，那麼...」 – pele

編輯並添加「如果這樣的事情是不可能的，那麼」，我希望你贊成編輯？ – pele

從dtd或xsd甚至xml文檔本身的NHibernate映射
