我试图计算数字节点的总和.以下代码不返回HTML以外的任何内容.我知道sum()采用节点集.我想我已经正确地创建了变量.我究竟做错了什么.
谢谢.

首先,输入文档包含一个默认命名空间:
<container xmlns="http://www.gtech.com/lsp/2009-09-23">
您需要考虑,即在引用输入文档时重新声明样式表和前缀元素.
然后,当您可以直接对您感兴趣的节点求和时,绝对不需要构造变量 - 但是某些CashPaymentsToday元素不包含数字:
<CashPaymentsToday>NONQUAL</CashPaymentsToday>
您需要从总和中排除这些元素.最后,在XSLT 1.0中,您当前正在做的事情是不可能的 - 因为该sum()函数不能将所谓的结果树片段作为参数.你的方法不应该"只返回html",它实际上应该失败.
