僅剝離空根元素

Question

我有一個輸入XML，它看起來像這樣，並希望使用XSL轉換如下所示的所需輸出。我一直在瀏覽博客，但找不到與如何刪除與根元素匹配的空標籤而不是子節點的任何相關信息。

<?xml version="1.0" encoding="UTF-8"?> 
<objects xmlns="urn:sobject.partner.soap.sforce.com"> 
    <Revenue__c/> 
    <Revenue__c/> 
    <Revenue__c/> 
    <Revenue__c> 
    <Sales_Org_ID__c>IV</Sales_Org_ID__c> 
    <Branch_ID__c>1</Branch_ID__c> 
    <Branch_Name__c>TEST</Branch_Name__c> 
    <Therapy_Code__c>TEST</Therapy_Code__c> 
    <Therapy_Name__c>TEST</Therapy_Name__c> 
    <Therapy_Class_Code__c>TEST</Therapy_Class_Code__c> 
    <Therapy_Class_Name__c>TEST</Therapy_Class_Name__c> 
    <Payor_Type_Name__c>TEST</Payor_Type_Name__c> 
    <Calendar_Year_Number__c>2011</Calendar_Year_Number__c> 
    <Month_Revenue_Amount__c>100.01</Month_Revenue_Amount__c> 
    <Payor_ID__c>TEST</Payor_ID__c> 
    <Payor_Name__c/> 
    <Payor_Type_Code__c>TEST</Payor_Type_Code__c> 
    <MDM_Account_EID__c>66600001</MDM_Account_EID__c> 
    <MDM_Physician_EID__c>99900001</MDM_Physician_EID__c> 
    <Account__c>001a000001APU5OAAX</Account__c> 
    <Contact__c>003a000001RL1EFAA1</Contact__c> 
    <Revenue_ID__c>41</Revenue_ID__c> 
    <Calendar_Year_Month__c>01</Calendar_Year_Month__c> 
    </Revenue__c> 
</objects> 

這正是我想要的了：

<?xml version="1.0" encoding="UTF-8"?> 
<objects xmlns="urn:sobject.partner.soap.sforce.com"> 
    <Revenue__c> 
    <Sales_Org_ID__c>IV</Sales_Org_ID__c> 
    <Branch_ID__c>1</Branch_ID__c> 
    <Branch_Name__c>TEST</Branch_Name__c> 
    <Therapy_Code__c>TEST</Therapy_Code__c> 
    <Therapy_Name__c>TEST</Therapy_Name__c> 
    <Therapy_Class_Code__c>TEST</Therapy_Class_Code__c> 
    <Therapy_Class_Name__c>TEST</Therapy_Class_Name__c> 
    <Payor_Type_Name__c>TEST</Payor_Type_Name__c> 
    <Calendar_Year_Number__c>2011</Calendar_Year_Number__c> 
    <Month_Revenue_Amount__c>100.01</Month_Revenue_Amount__c> 
    <Payor_ID__c>TEST</Payor_ID__c> 
    <Payor_Name__c/> 
    <Payor_Type_Code__c>TEST</Payor_Type_Code__c> 
    <MDM_Account_EID__c>66600001</MDM_Account_EID__c> 
    <MDM_Physician_EID__c>99900001</MDM_Physician_EID__c> 
    <Account__c>001a000001APU5OAAX</Account__c> 
    <Contact__c>003a000001RL1EFAA1</Contact__c> 
    <Revenue_ID__c>41</Revenue_ID__c> 
    <Calendar_Year_Month__c>01</Calendar_Year_Month__c> 
    </Revenue__c> 
</objects> 

任何建議將不勝感激。
