在XSLT中分組

Question

我對XSLT世界非常陌生，試圖解決下面提到的XML中的分組問題。我具有與ServiceChanges一起作爲根標記的相同XML。在根標記下，我可以有零個或多個CancelVisit和ChangedFrequency標記。在每個標籤中都有一個共同的字段FrequencyId。現在我的任務是根據Common FrequencyID將取消訪問和更改頻率標籤組合在一起（如果有的話），否則將被視爲獨立。

示例XML

<ServiceChanges> 
     <CancelVisit> 
      <VisitDate>2013-09-12</VisitDate>

       <Summary>3.00 hour(s) per week, every week, starting 06-Sep-2013 and ending 27-Sep-2013</Summary>

輸出所需 在上述XML，在第一CancelVist標籤的FrequencyID（fca44cac-7319-e311-8472-00155d051350）與第三ChangedFrequency標籤相匹配。現在我需要將它們組合在一起。 有可能所有標籤都具有相同的頻率ID。

輸出將首先顯示取消訪問和更改頻率。在上例 第一個和第三個標籤將被組合在一起，第二個和第四個標籤將被組合在一起。

我需要一個XSLT，任何幫助將非常感激。

Muenchian分組的是你在找什麼。看看XSLT 1.0 Group By和http://jenitennison.com/xslt/grouping/muenchian.html
