XSLT通过元素中提供的密钥对节点进行分组

2024-05-11 • 问答

我得到了一个讨厌的XML，其中的节点未按我想要的分组，而我试图找到一种通过节点中提供的<master_key>将其分组的方法：

原始xml ：

<root>
   <zasoba>
      <kod>388300-56</kod>
      <description>50cm</description>
      <master_key>388300MK</master_key>
      <kategorie/>
   </zasoba>
   <zasoba>
      <kod>388300-53</kod>
      <description>53cm</description>
      <master_key>388300MK</master_key>
      <kategorie/>
   </zasoba>
   <zasoba>
      <kod>388300MK</kod>
      <description>Master</description>
      <kategorie/>
   </zasoba>
   <zasoba>
      <kod>388399-56</kod>
      <description>56cm</description>
      <master_key>388399MK</master_key>
      <kategorie/>
   </zasoba>
   <zasoba>
      <kod>388399-57</kod>
      <description>57cm</description>
      <master_key>388399MK</master_key>
      <kategorie/>
   </zasoba>
   <zasoba>
      <kod>388399MK</kod>
      <description>Master 2</description>
      <kategorie/>
   </zasoba>
</root>

产品变体在各个元素中分开，但是我想在主元素（由master_key定义）下移动到新元素名称<variant>下。

输出应如下所示：

<root>
   <zasoba>
      <kod>388300MK</kod>
      <description>Master 2</description>
      <kategorie/>
      <variant>
         <kod>388300-56</kod>
         <description>50cm</description>
         <master_key>388300MK</master_key>
         <kategorie/>
      </variant>
      <variant>
         <kod>388300-53</kod>
         <description>53cm</description>
         <master_key>388300MK</master_key>
         <kategorie/>
      </variant>
   </zasoba>
   <zasoba>
      <kod>388399MK</kod>
      <description>Master</description>
      <kategorie/>
      <variant>
         <kod>388399-56</kod>
         <description>56cm</description>
         <master_key>388399MK</master_key>
         <kategorie/>
      </variant>
      <variant>
         <kod>388399-57</kod>
         <description>57cm</description>
         <master_key>388399MK</master_key>
         <kategorie/>
      </variant>
   </zasoba>
</root>
