我正在嘗試在XSLT中創建類信用總和，但我無法弄清楚在哪裏放置求和語句。使用XSLT對分組的XML工作流程中的數據進行求和
這裏是和發言中，我創建了：
<credit-sum><xsl:value-of select='format-number(sum(CRSMINCRED1),"##")'/></credit-sum>
將數據分組三次：
1. by Area of Study
2. By Degree
3. By Requirement or Elective status
我要總結只有學分「所需要的」類。但是當我把sum語句放在它中時，只是單獨顯示了每個類的總數而不是類組。
這裏是XSLT：
