PLSQL 解析XML示例2

1:PLSQL解析有嵌套的复杂XML数据，xml数据格式如下：

<ns1:IncreaseCreditAfterRemittance xmlns:ns1="http://tempuri.org/">
<ns1:parameters>
 <ns1:RemittanceParameterItem>
  <ns1:LeagueCompanyId>2001116</ns1:LeagueCompanyId> 
  <ns1:CompanyId>1000</ns1:CompanyId> 
  <ns1:RemittanceValue>65000.0</ns1:RemittanceValue> 
  <ns1:RemittanceToken>9591503</ns1:RemittanceToken> 
  <ns1:RemittanceDateTime>2018-09-26T14:51:22.0Z</ns1:RemittanceDateTime> 
  <ns1:Remark>640001391210002018</ns1:Remark>
  <ns1:test>
      <ns1:Remark1>123</ns1:Remark1>
      <ns1:Remark1>456</ns1:Remark1>
  </ns1:test>
  <orderLines>
    <orderLine>
      <orderLineNo></orderLineNo>
      <ownerCode>QBXA019</ownerCode>
      <itemCode>27313011617033329</itemCode>
      <planQty>0</planQty>
      <actualQty>1</actualQty>
    </orderLine>
    <orderLine>
      <orderLineNo></orderLineNo>
      <ownerCode>QBXA019</ownerCode>
      <itemCode>27313011617033339</itemCode>
      <planQty>0</planQty>
      <actualQty>1</actualQty>
    </orderLine>
   </orderLines>
  </ns1:RemittanceParameterItem>
  </ns1:parameters>
  </ns1:IncreaseCreditAfterRemittance>

　　

2：编写解析程序，increasecreditafterremittance为自定义type:

CREATE OR REPLACE FUNCTION decd_incr_creditafremittance1(p_node IN dbms_xmldom.domnode)
    RETURN increasecreditafterremittance IS
