Question

下午好，

我有一个函数，可以在我的DB中为模板构建一个输出XML结构的字符串。它将Order类作为参数和模板，我很难尝试填充名为[[items]]的占位符标记，其中根据表中项目的数量，它应该为该部分构建xml列表。

这是模板，它只返回字符串的一个实例，但它应该根据表中的内容返回（n）个实例。

<Items>
   [[items]]
</Items>

这是应该为项目的其他标签填充的内容

<Item>
 <SKU>[[item_sku]]</SKU>
 <PROD_NAME><![CDATA[[[item_product_name]]]]></PROD_NAME>
 <Description><![CDATA[[[item_name]]]]></Description>
 <Attributes><![CDATA[[[item_attributes]]]]></Attributes>
 <Quantity>[[item_qty]]</Quantity>
 <UnitPrice>[[item_price]]</UnitPrice>
 <InkColor>[[item_inkcolor]]</InkColor>
</Item>

它想要像这样填充

<Items>
  <Item>
    <SKU>7Z-BRPA-K79A</SKU>
    <PROD_NAME><![CDATA[Test One]]></PROD_NAME>
    <Description><![CDATA[ExcelMark 5-Line Large Return Address Stamp - Custom Self Inking Rubber Stamp]]></Description>
    <Attributes><![CDATA[Custom Text Line 1 Text: This book was donated to CAEO Font: Arial
                Custom Text Line 2 Text: In tribute to & memory of Font: Arial]]></Attributes>
    <Quantity>1</Quantity>
    <UnitPrice><![CDATA[$9.99]]></UnitPrice>
    <InkColor>Red</InkColor>
  </Item>
  <Item>
    <SKU>42A1848</SKU>
    <PROD_NAME><![CDATA[Test Two]]></PROD_NAME>
    <Description><![CDATA[Self Inking Rubber Stamp with up To 4 Lines of Custom Text]]></Description>
    <Attributes><![CDATA[Custom Text Line 1 Text: This book was donated to CAEO Font: Arial
                Custom Text Line 2 Text: In tribute to & memory of Font: Arial]]></Attributes>
    <Quantity>1</Quantity>
    <UnitPrice><![CDATA[$8.99]]></UnitPrice>
    <InkColor>Blue</InkColor>
  </Item>
</Items>

这是实现它的功能

public string PopulateStringBuilder(Order order, Template template)
    {
        var i = new StringBuilder(template.Description);
        List<string> s = new List<string>();
        var reqID = order.OrderId;

            foreach (var x in order.Items)
            {
                i.Replace("[[item_sku]]", x.SkuNumber);
                i.Replace("[[item_product_name]]", x.ProductName);
                i.Replace("[[item_name]]", x.Description);
                i.Replace("[[item_attributes]]", x.Attributes);
                i.Replace("[[item_qty]]", x.Quantity.ToString());
                i.Replace("[[item_price]]", x.UnitPrice.ToString());
                i.Replace("[[item_inkcolor]]", x.InkColor);
                o.Replace("[[items]]", i.ToString());
            }  
        return o.ToString();
    }

无法返回XML格式的字符串，使用C＃中的stringbuilder和DB模板，对于PlaceHolder
