使用pl sql将xml文件解析为2个oracle标头详细信息表

我试图通过pl sql解析xml文件。有一个标题部分（GrpHdr），其中包含一个Id元素，该元素应插入到特定表及其详细信息（Ntfctn）中，其元素将插入到另一个表中，外键是第一个表的Id。文件如下：

<?xml version="1.0" encoding="utf-8" standalone="no"?>

可以使用XMLTABLE函数从XML中提取行。作为测试，我创建了一个名为“text”的表，其中一列名为“xmldata”

然后，您可以像这样从XML文档中查询数据：

select header.id, data.*
from test, xmltable(-- GrpHdr as table
        xmlnamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.054.001.03', 'urn:DMCTfh:xsd:$DIASMCTFH' as "DMCTfh" ),
        '/DMCTfh:DIASMCTFH/DMCTfh:BkToCstmrDbtCdtNtfctn/GrpHdr' 
        passing test.xmldata
        columns id varchar2(50) path 'MsgRcpt/Id/OrgId/Othr/Id'
    ) as header, 
    xmltable(-- Ntfctn as table
        xmlnamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.054.001.03', 'urn:DMCTfh:xsd:$DIASMCTFH' as "DMCTfh" ),
        '/DMCTfh:DIASMCTFH/DMCTfh:BkToCstmrDbtCdtNtfctn/Ntfctn' 
        passing test.xmldata
        columns iban varchar2(50) path 'Acct/Id/IBAN',
            dt varchar2(50) path 'Ntry/ValDt/Dt' -- and so on
    ) as data;

select header.id, data.*
from test, xmltable(-- GrpHdr as table
        xmlnamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.054.001.03', 'urn:DMCTfh:xsd:$DIASMCTFH' as "DMCTfh" ),
        '/DMCTfh:DIASMCTFH/DMCTfh:BkToCstmrDbtCdtNtfctn/GrpHdr' 
        passing test.xmldata
        columns id varchar2(50) path 'MsgRcpt/Id/OrgId/Othr/Id'
    ) as header, 
    xmltable(-- Ntfctn as table
        xmlnamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.054.001.03', 'urn:DMCTfh:xsd:$DIASMCTFH' as "DMCTfh" ),
        '/DMCTfh:DIASMCTFH/DMCTfh:BkToCstmrDbtCdtNtfctn/Ntfctn' 
        passing test.xmldata
        columns iban varchar2(50) path 'Acct/Id/IBAN',
            dt varchar2(50) path 'Ntry/ValDt/Dt' -- and so on
    ) as data;
