Question

我正在嘗試在biztalk - orchestration中使用xpath在我的edifact文件的最後一行元素中查找IMD。 這是我的XPath：

LastLineName = xpath(Message_2,"/*[local-name()='EFACT_D96A_INVOIC' and namespace-uri()='http://schemas.microsoft.com/BizTalk/EDI/EDIFACT/2006']/*[local-name()='LINLoop1' and namespace-uri()='http://schemas.microsoft.com/BizTalk/EDI/EDIFACT/2006']/*[local-name()='IMD_2' and namespace-uri()='http://schemas.microsoft.com/BizTalk/EDI/EDIFACT/2006']/*[local-name()='C273_2' and namespace-uri()='http://schemas.microsoft.com/BizTalk/EDI/EDIFACT/2006']/*[local-name()='C27304' and namespace-uri()='']last()"); 

這是我edifat文件：

它返回：

具有無效令牌

Answer 1

在很最後，你有

last()

位置索引器必須用方括號括起來。

所以，簡單地使其：

[last()]

Answer 2

我解決它。對不起，阿蘭，你對[last（）]完全正確。我只是需要把它放在另一個地方而不是建議的地方。

這是解決方案：
