我想返回的每时间表L1和L0项目的数量和也警告的数量,也按计划.
这实际上是一个"数量如果"的情况.
我尝试了以下XQuery,它可以很好地计算L1,L0和警告,但会计算所有警告,而不是仅计算所有警告value = "yes".
xquery version "3.0";
let $nl := " "
let $quote := """
let $pipe := "|"
let $nodecount := 0
for $profiles in doc("maik test.xml")/PROFILE
for $schedule in $profiles/SCHEDULE
let $schedulename := $schedule/@name
group by $schedulename
return ($nl,
$schedulename, $pipe, "L0 count:", count($schedule/L0),
$pipe, "L0 Warnings:", count($schedule/L0/ATTRIBUTE[@NAME = "Warnings"]/VALUE/string() = "Yes"),
$pipe, "L1 count:", count($schedule/L0/L1),
$pipe, "L1 Warnings:", count($schedule/L0/L1/ATTRIBUTE[@NAME = "Warnings"]/VALUE/string() = "Yes"))
