      .parent()

      Description of the method
      Description:

      .parent() navigates to the parent of the element. It can be used to  reach over the context of the rule.
      Available for:

      any element
      Parameters: parent element type 
      Return type: element

      Example 1

      Context: CreditTransferTransactionInformation
      OCL: self.parent(PaymentInstructionInformation).PmtTpInf.SvcLvl.Cd.matches("SEPA")
      Description: The example rule checks if the parent element has Service level code populated with value SEPA.

       

      The XML snippet below would pass this check.

      <PmtInf>
            <PmtInfId>1234</PmtInfId>
            <PmtMtd>TRF</PmtMtd>
            <PmtTpInf>
              <SvcLvl>
                <Cd>SEPA</Cd>
              </SvcLvl>
            </PmtTpInf>
            <ReqdExctnDt>2023-01-01</ReqdExctnDt>
            ...
            <CdtTrfTxInf>
              <PmtId>
                <EndToEndId>12345</EndToEndId>
              </PmtId>
              <Amt>
                <InstdAmt Ccy="EUR">100</InstdAmt>
              </Amt>
              ...
            </CdtTrfTxInf>
          </PmtInf>

      The other snippet below however would not pass this check as the value is different from "SEPA".

      <PmtInf>
            <PmtInfId>1234</PmtInfId>
            <PmtMtd>TRF</PmtMtd>
            <PmtTpInf>
              <SvcLvl>
                <Cd>NURG</Cd>
              </SvcLvl>
            </PmtTpInf>
            <ReqdExctnDt>2023-01-01</ReqdExctnDt>
            ...
            <CdtTrfTxInf>
              <PmtId>
                <EndToEndId>12345</EndToEndId>
              </PmtId>
              <Amt>
                <InstdAmt Ccy="EUR">100</InstdAmt>
              </Amt>
              ...
            </CdtTrfTxInf>
          </PmtInf>
