将多个 XML 文件合并为一个 XML

本文关键字：XML 一个 合并 文件 | 更新日期: 2023-09-27 18:33:30

我有一堆XML，我想从所有这些XML中生成1个XML（以相同的格式）。

这是 1 的示例.XML

<?xml version="1.0" encoding="UTF-8"?>
<RootDTO xmlns:json='http://james.newtonking.com/projects/json'>
   <destination>
      <name>xxx</name>
   </destination>
   <orderData>                                         
      <items json:Array='true'>  
            <shipmentIndex Name="items"></shipmentIndex>
            <barcode>12345</barcode>                                                                                                       
      </items>  
      <misCode>9876543210</misCode>                                      
          <shipments>                                      
                <sourceShipmentId></sourceShipmentId>      
                <shipmentIndex Name="shipments"></shipmentIndex>                         
          </shipments>                         
   </orderData>
</RootDTO>

这个表示将 1.xml 和 2.xml 组合后的结果.xml（看起来与 1 完全相同.xml

<!-- Represent Result.xml-->
<?xml version="1.0" encoding="UTF-8"?>
<RootDTO xmlns:json='http://james.newtonking.com/projects/json'>
   <destination>
      <name>xxx</name>
   </destination>
   <orderData>                                         
      <items json:Array='true'>  
            <shipmentIndex Name="items"></shipmentIndex>
            <barcode>12345</barcode>                                                                                                       
      </items>  
    <items json:Array='true'>     <!-- from 2.xml-->
            <shipmentIndex Name="items"></shipmentIndex>
            <barcode>12345</barcode>                                                                                                       
      </items>  

      <misCode>9876543210</misCode>                                      
          <shipments>                                      
                <sourceShipmentId></sourceShipmentId>      
                <shipmentIndex Name="shipments"></shipmentIndex>                         
          </shipments>     

      <shipments>       <!--From 2.xml-->                              
                <sourceShipmentId></sourceShipmentId>      
                <shipmentIndex Name="shipments"></shipmentIndex>                         
          </shipments>                             
   </orderData>
</RootDTO>

这样做的目的是将多个货件（一起，它们是 1 个订单）合并为 1 个代表完整订单的 XML。

像这样伪：

for(i=0; i< xmls.count()< i++)
{
   itemsElement.appendTo(xml[i].items);
   shipmentsElement.appendTo(xml[i].shipments);
}

我想要实现的是附加元素 - "项目"和"装运"转换为 1 个表示订单的 XML。

我正在使用此代码使我的 XML strng：var xml = XElement.Parse(renderedOutput);表示我的 XML 字符串

将多个 XML 文件合并为一个 XML

为了简化示例代码，我将相同的 xml 添加到同一文档中三次。 可以使用 Load 方法而不是 Parse 从文件而不是字符串中获取 xml。
