如何编写XPath表达式来选择lockerEntryEvents的数量,以及在lockerEntries下的内容以及policyId = ps_d8d的位置
我试过了
(//lockerEntries[policyId="ps_d8d"]//count(//lockerEntryEvents))
但它不起作用。现在应该是count = 4
谢谢
答案 0 :(得分:3)
“如何编写XPath表达式以选择
下lockerEntryEvents
lockerEntries
以及policyId=ps_d8d
count(//lockerEntries[policyId='ps_d8d']/lockerEntryEvents)
的数量
这是正确的XPath:
4
