我在这里遇到一个问题，我需要一些帮助。看看这些行：

HEADING
TYPE       NAME      PBOR0    SHOP     CATREF    DETAIL    MATXT    CMPREF    BLTREF    TMPREF     PRTREF
DEFAULTS
-           -        -       =
TUBE       */Cb_N76f-RDX/T0A2013010-00:DD 0.50     TRUE  /RDX_R_AAPA1A0DD /RDX_T0A2013010-00 /RDX_VAZIO-MT   /Cb_N76f-RDX/RDX_T0A0AC0010-00:DD =0          =0          =0

还有这些行：

HEADING
TYPE       NAME      PBOR0    STYP    SHOP     CATREF    DETAIL    MATXT    CMPREF    BLTREF    TMPREF     PRTREF
DEFAULTS
-           -        -   CT      =
ELBO       */C9B0020101-00:DD 0.50     CT  TRUE  /RDX_R_ABEB360DD /C9B0020101-00  /RDX_VAZIO-MT   /Cb_N76f-RDX/RDX_C9B002AC01-00:DD =0          =0          =0

正如您在上面看到的，第一个块来自 TUBE，第二个块来自 ELBO。两者都有不同的标题列。这个问题我解决了这样的xml配置：

现在的问题是：我有很多不同的规则来写列中的值，例如：写 NAME 我必须遵循某些规则，写 STYP 另一个等等。有没有一种简单易行的方法来描述这些规则一个 XML，读取和解释它们并根据输出中的规则写入正确的值？

提前谢谢各位！

If you create classes for each type, then you would have the rules. You'd have the API for that xml to read/write with. The advantage of classes, written in C# they are strongly typed.

Example,

public class Elbo
{
    XElement self;
    public Elbo(XElement elbo) { self = elbo; }

    public string Name
    {
         get { return self.Element("Name").Value; }
         set 
         { 
               XElement name = self.Element("Name");
               if(null == name)
                    self.Add(name = new XElement("Name"));
               name.Value = value;
         }
    }
}

Now Name is strongly typed, only a string can be written to it and read from it. Also this is an example, you have a lot more rules (nodes) such as Column nodes etc that I skipped over. I hope you get the point of what I wrote.

If you go with your generic approach of generic columns that can hold anything and any type, then you are going to have a lot more difficult time of developing rules to govern it all.

尝试结帐：

  • 常用表达
  • 使用 XSD 模式进行验证（我怀疑是这种情况）

可能这不是您期望的那么酷的答案，但无论如何
