我被卡在xquery中的某个位置。在响应中,我想取回每个类型的电话号码,即HOME和CELL,但只返回序列号最高的电话号码。如果有两行的PhoneType =“ HOME”,我要取回序列号最高的电话的两个,即在我的情况下为Sequence =“ 3”。
使用我的xquery,我可以取回phoneType =“ HOME”和第一行,其类型为HOME。我也无法添加条件来检查序列。我在哪里以及如何添加它。请提出建议。预先感谢
我的Xquery的一部分:
<acc:phones>
{
for $PersonPhonesRow in $PersonMaintenanceResponse/ns2:CMPersonService/ns2:CMPersonDetails/ns2:PersonPhones/ns2:PersonPhonesRow[@PhoneType="HOME"][1]
return
if(fn:data($PersonMaintenanceResponse/ns2:CMPersonService/ns2:CMPersonDetails/ns2:PersonPhones/ns2:PersonPhonesRow/@PhoneType="HOME"[1]))
then
<com:phone>
<com:type>{'HOME'}</com:type>
<com:phoneNumber>{fn:data($PersonMaintenanceResponse/ns2:CMPersonService/ns2:CMPersonDetails/ns2:PersonPhones/ns2:PersonPhonesRow[@PhoneType="HOME"][1]/@PhoneNumber)}</com:phoneNumber>
<com:carrier>{fn:data($PersonMaintenanceResponse/ns2:CMPersonService/ns2:CMPersonDetails/ns2:PersonPhones/ns2:PersonPhonesRow[@PhoneType="HOME"][1]/@Extension)}</com:carrier>
</com:phone>

要使用的查询:
let $PersonMaintenanceResponse := 'Your request'
let $uniqPhoneType :=distinct-values($PersonMaintenanceResponse/ns2:CMPersonService/ns2:CMPersonDetails/ns2:PersonPhones/ns2:PersonPhonesRow/@PhoneType)
for $each at $i in $uniqPhoneType
return
<acc:phones>
{
let $seq := $PersonMaintenanceResponse/ns2:CMPersonService/ns2:CMPersonDetails/ns2:PersonPhones/ns2:PersonPhonesRow[(@PhoneType = $each)]
let $maxValue := max($seq/@Sequence)
let $maxrow := $seq[@Sequence eq $maxValue]
return
<com:phone xmlns:com="*******">
<com:type>{$each}</com:type>
<com:phoneNumber>{$maxrow/@PhoneNumber}</com:phoneNumber>
<com:carrier>{$maxrow/@Extension}</com:carrier>
</com:phone>
}</acc:phones>
