XSL复杂的转换与排序，添加和删除元素

Question

我想要使用XSLT转换XML文档，但我有困难，因为有多个处理任务要在XML文档上执行。

这里是我要找的步骤来完成（对不起，我不知道这甚至有可能，或者我会尝试一些其他方式）：

1 - 带/删除所有<group>元件和放/相邻<relation>元件移动到下一个元素<filter>

2 - 排序所有<filter>元件由两个元素中称为<relation>和<filtertype>

3 - 重组的所有<filter>个元件通过<relation>和通过<filtertype>通过添加回<group>元件和在<group>

换句话说拉动<relation>元件从所述第一<filter>元件的，我试图撤消所有现有的分组，排序所有的过滤器通过类似过滤类型和关系的元素，然后通过常见的filtertype和relation将过滤器重新组合，因为知道第一个组元素必须具有从其第一个过滤元素移动到组元素的关系元素

对不起，如果这很让人困惑，我的样品是低于（预先感谢）
