oracle解析xml，带命令空间的节点获取

在xml里有两个解析xml的函数extract和extractVALUE，这两个函数可以带两个参数，也可以带上个参数,第三个参数是命令空间，对于namespace_string,刚开始我也很疑惑，然后去网上找了很久的资料也没弄明白，因为没有范例，最后在自己的尝试下解决了，

extract官网API如下：

样例xml报文如下：

直接获取节点或者节点值样例sql如下：

select extract(xmltype('<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:euc="http://platform.nucleusconnect.com/wsdl/EUCServices">

    </euc:AuthHeaderRequest>
  </soapenv:Header>
  <soapenv:Body>
    <euc:EUCRevisionNewOrderRequest>
      <header>
        <Department>Business Solution - Business broadband</Department>
        <AcceptTNC>Yes</AcceptTNC>
        <TransactionId>FB000120170119181518436</TransactionId>
      </header>

        <SalesOrderId>2017011914381897</SalesOrderId>
      </body>
    </euc:EUCRevisionNewOrderRequest>
  </soapenv:Body>
</soapenv:Envelope>'),'/soapenv:Envelope/soapenv:Body/euc:EUCRevisionNewOrderRequest/body','xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:euc="http://platform.nucleusconnect.com/wsdl/EUCServices"')
  from dual a

select extractVALUE(xmltype('<?xml version="1.0" encoding="utf-8"?>

 from dual a

通过xmltable转换为表格sql样例如下：

SELECT *
  FROM XMLTABLE(XMLNAMESPACES('http://schemas.xmlsoap.org/soap/envelope/' AS
                              "soapenv1",'http://platform.nucleusconnect.com/wsdl/EUCServices' AS
                              "euc1"),'$B/soapenv1:Envelope/soapenv1:Body/euc1:EUCRevisionNewOrderRequest/body'
                PASSING
                (select xmltype('<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:euc="http://platform.nucleusconnect.com/wsdl/EUCServices">
  <soapenv:Header>
    <euc:AuthHeaderRequest>
      <userName>User1</userName>
      <Token>45df847e-c02e-64d4-f6a1-76a9c8f2c537</Token>
    </euc:AuthHeaderRequest>
  </soapenv:Header>
  <soapenv:Body>
    <euc:EUCRevisionNewOrderRequest>
      <header>
        <Department>Business Solution - Business broadband</Department>
        <AcceptTNC>Yes</AcceptTNC>
        <TransactionId>FB000120170119181518436</TransactionId>
      </header>
      <body>
        <SalesOrderId>2017011914381897</SalesOrderId>
      </body>
    </euc:EUCRevisionNewOrderRequest>
  </soapenv:Body>
</soapenv:Envelope>')
                   from dual a ) AS B COLUMNS SalesOrderId
                VARCHAR2(128) PATH '/body/SalesOrderId')
