我正在使用XSLT将XML转换为某种文件格式。我排除了匹配两个字段（OrigTxnId和TxnId）的冲销交易。问题是我在标题中为交易数量所做的计数仍包括已被移除的交易。为什么XSLT计数函数无法按预期工作？
。由此输入XML exsample：
<XML>
<Record><GroupId>10028</GroupId><Id>1</Id><User>CHRISVI</User><TxnId>264-10028-1-516739-2</TxnId><Date>30-Sep-2014</Date><Time>12:21:24</Time><Account>12440531</Account><Amount>217090</Amount><AllowableMOP>0</AllowableMOP><BankBranchCode>280071</BankBranchCode><ChequeAccNo>62247628681</ChequeAccNo><ChequeNo>000040</ChequeNo></Record>
<Record><GroupId>10028</GroupId><Id>1</Id><User>CHRISVI</User><TxnId>264-10028-1-516743-2</TxnId><Date>30-Sep-2014</Date><Time>12:21:52</Time><Account>10895388</Account><Amount>150000</Amount><AllowableMOP>1</AllowableMOP></Record>
<Record><GroupId>10028</GroupId><Id>1</Id><User>CHRISVI</User><TxnId>264-10028-1-516748-1</TxnId><Date>30-Sep-2014</Date><Time>12:22:26</Time><OrigTxnId>264-10028-1-516743-2</OrigTxnId><Account>10895388</Account><Amount>150000</Amount><AllowableMOP>1</AllowableMOP></Record>
<Record><GroupId>10028</GroupId><Id>1</Id><User>CHRISVI</User><TxnId>264-10028-1-516756-1</TxnId><Date>30-Sep-2014</Date><Time>12:23:01</Time><Account>10895388</Account><Amount>10000</Amount><AllowableMOP>1</AllowableMOP></Record>
<Record><GroupId>10028</GroupId><Id>1</Id><User>CHRISVI</User><TxnId>264-10028-1-516760-2</TxnId><Date>30-Sep-2014</Date><Time>12:23:24</Time><Account>10605762</Account><Amount>15000</Amount><AllowableMOP>1</AllowableMOP></Record>
</XML>

你可以尽量减少的例子，只什么必要证明的问题（使你的代码在它可读）？确保也包含一个示例输入XML。 - 另外：XSLT处理（例如计数）输入XML，而不是输出树。 – 2014-09-30 11:52:15
@Michael，我在XSLT代码中引用以下内容：<？NUMRECORDS？>
我是抱歉，我没有时间编辑您的代码。请发布可以复制，粘贴并运行的内容以显示问题。 – 2014-09-30 12:25:16
