XSL複雜的轉換與排序，添加和刪除元素

Question

我想要使用XSLT轉換XML文檔，但我有困難，因爲有多個處理任務要在XML文檔上執行。

這裏是我要找的步驟來完成（對不起，我不知道這甚至有可能，或者我會嘗試一些其他方式）：

1 - 帶/刪除所有<group>元件和放/相鄰<relation>元件移動到下一個元素<filter>

2 - 排序所有<filter>元件由兩個元素中稱爲<relation>和<filtertype>

3 - 重組的所有<filter>個元件通過<relation>和通過<filtertype>通過添加回<group>元件和在<group>

換句話說拉動<relation>元件從所述第一<filter>元件的，我試圖撤消所有現有的分組，排序所有的過濾器通過類似過濾類型和關係的元素，然後通過常見的filtertype和relation將過濾器重新組合，因爲知道第一個組元素必須具有從其第一個過濾元素移動到組元素的關係元素

對不起，如果這很讓人困惑，我的樣品是低於（預先感謝）
