Dankeschön für die Tipps!

Ist es auch möglich tiefer verschachtelte XMLs in eine PF zu schreiben?
Also dass ich in Customer noch Customer1 habe und er mir die Werter zu jedem Customer Satz hinzufügt?
HTML-Code:
<Customer>
    <CustomerNo>1000000315</CustomerNo>
    <NoOfSuccessfullOrders>2</NoOfSuccessfullOrders>
    <Currency>EUR</Currency>
    <Balance>-10.85</Balance>
    <Collection>0</Collection>
    <ReturnQuote>33</ReturnQuote>
    <ReturnQuoteAmount>10</ReturnQuoteAmount>
    <Customer1>
     <Nummer>1</Nummer>
    </Customer1>
  </Customer>    
     1
Code:
          select info_req.*
          from xmltable('/ExCustomerDataList/Customer'
               passing xmlparse(document get_xml_file('/home/codaho/test.xml'))
               columns
        RIONID         varchar(20)     path 'CustomerNo',
        RIANZA         varchar(5)      path 'NoOfSuccessfullOrders',
        RIAUFO         decimal(11, 2)  path 'Balance',
        RIAUFU         decimal(11, 2)  path 'BalanceOverdueOpenAssets',
        RIMAHN         varchar(2)      path 'MaxActReminderLevel',
        RIIKSA         varchar(1)      path 'Collection',
        RIRQST         decimal(5, 2)   path 'ReturnQuote',
        RIRQZS         decimal(5, 2)   path 'ReturnQuoteOverTime',
        RIRQWT         decimal(5, 2)   path 'ReturnQuoteAmount',
        RIRQZW         decimal(5, 2)   path 'ReturnQuoteAmountOverTime',
        NUMMER         varchar(20)     path 'Customer1/Nummer'


                       ) info_req
wäre meine Idee dazu gewesen
