I have sample Query with XML like below:

with t(xml) as 
(
select xmltype(
'<SSO_XML
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Target="Production" 
Version="1.0" 
TransactionIdentifier="PLAN_A" 
SequenceNmbr="123456"
    xmlns="http://www.w3.org/2001/XMLSchema">
    <PlanCode PlanCodeCode="CHOICE">
        <S_DAYS FARE="10" Start="2020-08-07" End="2020-10-30" Mon="true" Tue="true" Weds="true" Thur="true" Fri="true" Sat="true" Sun="true">
            <STUDENT>
                <DIVISION ORIGINAL="150.05" Code="Flat" S_CODE="1" />
                <DIVISION ORIGINAL="150.05" Code="Flat" S_CODE="2" />
            </STUDENT>
        </S_DAYS>
    </PlanCode>
</SSO_XML>') 
 from dual
 )

select h.PlanCodeCode
,b.Original
,b.code
,b.s_code
 from   t
    cross join
    xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
             '/SSO_XML'
             passing t.xml
             columns PlanCodeCode varchar2(100)  path './PlanCode/@PlanCodeCode',
                     attributes xmltype path './PlanCode'
            ) h
    cross join xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
             'PlanCode/S_DAYS/STUDENT/DIVISION'
             passing h.attributes
             columns 
                    ORIGINAL number path  '@ORIGINAL',
                    Code            varchar2(100) path '@Code',
                    S_CODE  number path '@S_CODE'
            ) b;

Output:

I am trying to fetch the values below within the query or a new query: Is there any way to do that? Any help / direction appreciated.

Solution

  • You just have to complete your first XMLTABLE query (h) in this way:

    target  varchar2(100) path '/SSO_XML/@Target',
transactionId  varchar2(100) path '/SSO_XML/@TransactionIdentifier'
