我正在尝试使用 XSLT 转换 XML 文档，但我遇到了困难，因为要对 XML 文档执行多个处理任务。

以下是我希望完成的步骤（抱歉，我不确定这是否可能，或者我是否必须尝试其他方法）：

1 - 剥离/删除所有<group>元素并将相邻<relation>元素放入/移动到下一个<filter>元素

2 - 通过调用和<filter>中的两个元素对所有元素进行排序<relation><filtertype>

3 -通过添加元素并将元素从第一个元素中拉出，重新组合所有<filter>元素<relation><filtertype><group><relation><filter><group>

换句话说，我正在尝试撤消所有现有的分组，按过滤器类型和关系对所有过滤器元素进行排序，然后通过公共过滤器类型和关系重新对过滤器进行分组，因为知道第一个组元素必须有一个被移动的关系元素从它的第一个过滤器元素到组元素

抱歉，如果这令人困惑，我的示例如下（提前致谢）

输入 XML

<mainXML>
   <version major="1" minor="0" build="0" revision="0"/>
   <id>30</id>
   <set>Partial</set>
   <evaluate>True</evaluate>
   <group>
      <relation>And</relation>
      <filter>
         <filtertype>Search</filtertype>
         <attributeid>32900</attributeid>
         <action>
            <type>Numeric</type>
            <operator>GreaterThanOrEqualTo</operator>
            <value>01001</value>
         </action>
      </filter>
      <filter>
         <relation>Or</relation>
         <filtertype>Search</filtertype>
         <attributeid>32900</attributeid>
         <action>

         <filtertype>Search</filtertype>
         <attributeid>32900</attributeid>
         <action>
            <type>Numeric</type>
            <operator>GreaterThanOrEqualTo</operator>
            <value>30001</value>
         </action>
      </filter>
   </group>
   <group>
      <relation>And</relation>
      <filter>
         <filtertype>Grouping</filtertype>
         <action>
            <type>Mailing</type>
            <operator>DoNotBelongTo</operator>
            <groupingid>1133519</groupingid>
         </action>
      </filter>
      <filter>
         <relation>And</relation>
         <filtertype>Action</filtertype>
         <campaign>
            <campaignid>1509779</campaignid>
         </campaign>
         <action>
            <status>DoNot</status>
            <operator>Bill</operator>
         </action>
         <operator>AfterNHour</operator>
         <value>36</value>
      </filter>
      <filter>
         <relation>Or</relation>
         <filtertype>Action</filtertype>
         <campaign>
            <campaignid>1509779</campaignid>
         </campaign>
         <action>
            <status>DoNot</status>       
         </action>
         <operator>AfterNHour</operator>
         <value>36</value>
      </filter>
   </group>
</mainXML>

所需的输出 XML

<mainXML>
   <version major="1" minor="0" build="0" revision="0"/>
   <id>30</id>
   <set>Partial</set>
   <evaluate>True</evaluate>
