xml - oracle中xmlconcat函数的使用方法

Question

我想使用 xmlconcat 函数，以便我的 xml 如下所示：

<BusProcess>
<CRR>
<CUSIP>65443W404</CUSIP>
<RUP>100</RUP>
<ACB>2500</ACB>
</CRR>
<LEI>546</LEI>
<AddModCDIC>
<CDICData>
<UCIData>
<UCI>BMO2100001200001</UCI>
<InterestlnDeposit>50</InterestlnDeposit>
</UCIData>
<UCIData>
<UCI>BMO2100005500012</UCI>
<InterestlnDeposit>50</InterestlnDeposit>
</UCIData>
</CDICData>
</AddModCDIC>
</BusProcess>

有人可以帮助调试我的代码以获得上述结果

select XMLELEMENT ("BusProcess",XMLFOREST(
XMLFOREST('65443W404' as "CUSIP",100 as "RUP", 2500 as "ACB") as "CRR",
(CASE WHEN 1=1 THEN XMLCONCAT (xmlelement ("LEI",a.vcud_lei ),XMLELEMENT("CDICData", 
XMLAGG(  XMLELEMENT("UCIData",xmlforest(a.vcud_uci as "UCI",a.vcud_per as "InterestlnDeposit")))))  
END ) as "AddModCDIC") )

from vw_cdic_uci_detail a 
where vcud_clcode in ('21000055','21000012');
