我尝试在 pl/sql 中解析这个 xml 中的值。

我想获得<tax:resultCode>1</tax:resultCode>标签值，以便它的'1'

你能帮我吗 ：（ ？

像这样的东西

with xml as (select xmltype('<here you xml from question>') x from dual)

select EXTRACTVALUE(xml.x,'//tax:resultCode','xmlns:tax="http://www.avea.com.tr/TAXIM_INVENTORY_OPERATIONS"')
 from xml

这里输出

EXTRACTVALUE(XML.X,'//TAX:RESULTCODE','XMLNS:TAX="HTTP://WWW.AVEA.COM.TR/TAXIM_I
--------------------------------------------------------------------------------
1

"//" 用于标识当前节点的所有后代。例如，PurchaseOrder//ShippingInstructions 匹配 PurchaseOrder 元素下的任何 ShippingInstructions 元素。https://docs.oracle.com/cd/B19306_01/appdev.102/b14259/xdb04cre.htm#g1038245

或者您可以这样做（此表达式将找到所有节点，甚至是绑定到您不感兴趣的名称空间的节点。）

with xml as (select xmltype('<here you xml from question>') x from dual)
select EXTRACTVALUE(xml.x,'//*[local-name()="resultCode"]') from xml

或者你可以从根元素走很长一段路：

    with xml as (select xmltype('<here you xml from question>') x from dual)

select 
       extract(soapbody.column_value,
      '/tax:checkInventoryResponse/tax:ResponseBody/tax:response/tax:ResponseItem/tax:resultCode/text()',
      'xmlns:tax="http://www.avea.com.tr/TAXIM_INVENTORY_OPERATIONS"').getNumberVal()
from xml,
     TABLE(XMLSequence(extract(xml.x, '/soapenv:Envelope/*','xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"'))) soapenv,
     TABLE(XMLSequence(extract(soapenv.column_value, '/soap:Body/*','xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"'))) soapbody

对于 pl/sql 语句，它必须如下所示：

declare
 l_value varchar2(1);
begin

with xml as (select xmltype('<here you xml from question>') x from dual)

select EXTRACTVALUE(xml.x,'//tax:resultCode','xmlns:tax="http://www.avea.com.tr/TAXIM_INVENTORY_OPERATIONS"')
into l_value
 from xml;

end;
