从 Oracle 中的 XML 列中提取值

Question

我在 Oracle table 中有一些数据存储在 XML 格式的字符串中（table WS_LOG 中的 response 列）。

我想从 <MedicalProcedureOutput> 下面的每个不同节点提取数据，但我在到达每个节点时遇到了一些困难。你能发现我做错了什么吗？

这是我正在尝试的（此处尝试检索 icpcID 标记的值）：

 SELECT a.id,
  t1.icpcID FROM
  GH.WS_LOG a, 
  xmltable(
  xmlnamespaces(
'http://schemas.xmlsoap.org/soap/envelope/' as "soap",
'http://www.w3.org/2001/XMLSchema' as "xsd",
'http://www.w3.org/2001/XMLSchema-instance' as "xsi"),
'/soap:Envelope/soap:Body/createBillingSubmissionForAFEBSGResponse/createBillingSubmissionForAFEBSGResult/proceduresList/MedicalProcedureOutput' passing xmltype(a.response) columns
icpcID varchar2(50) path 'ipcdId') t1

下面是一些示例数据

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soap:Body>
      <createBillingSubmissionForAFEBSGResponse xmlns="urn:bcpcorp.net/ws/bsgFacets/FacetsBillingService">
         <createBillingSubmissionForAFEBSGResult>
            <status>0</status>
            <outputMessage />
            <statusElement />
            <claimID>18E002021300</claimID>
            <claimStatus>01</claimStatus>
            <claimStatusReason>AGFP</claimStatusReason>
            <totalChargeValue>35.0000</totalChargeValue>
            <totalPayableValue>0.0000</totalPayableValue>
            <paitentPaidvalue>17.5</paitentPaidvalue>
            <totalDebitAmount>0</totalDebitAmount>
            <proceduresList>
               <MedicalProcedureOutput>
                  <ipcdId>011801</ipcdId>
                  <otherdisallowedAmountResponsibility>N</otherdisallowedAmountResponsibility>
               </MedicalProcedureOutput>
            </proceduresList>
         </createBillingSubmissionForAFEBSGResult>
      </createBillingSubmissionForAFEBSGResponse>
   </soap:Body>
</soap:Envelope>

我希望得到值“011801”。请注意，可能会出现多个 <MedicalProcedureOutput> 个节点，它们的组织方式如下：


               <MedicalProcedureOutput>
                  <ipcdId>725013</ipcdId>     
          <otherdisallowedAmountResponsibility>N</otherdisallowedAmountResponsibility>
               </MedicalProcedureOutput>

               <MedicalProcedureOutput>
                  <ipcdId>725105</ipcdId>   
            <otherdisallowedAmountResponsibility>N</otherdisallowedAmountResponsibility>
               </MedicalProcedureOutput>

Answer 1

你应该看看用 EXTRACTVALUE 函数解决它，here You can find 一些关于它的信息。

Answer 2

您需要为正文中的所有内容声明默认名称空间，因为 createBillingSubmissionForAFEBSGResponse 有自己的 xmlns 未命名（因此默认）声明，该声明从该节点开始应用；所以：

SELECT a.id,
  t1.icpcID FROM
  GH.WS_LOG a,
  xmltable(
  xmlnamespaces(
default 'urn:bcpcorp.net/ws/bsgFacets/FacetsBillingService',
'http://schemas.xmlsoap.org/soap/envelope/' as "soap",
'http://www.w3.org/2001/XMLSchema' as "xsd",
'http://www.w3.org/2001/XMLSchema-instance' as "xsi"
),
'/soap:Envelope/soap:Body/createBillingSubmissionForAFEBSGResponse/createBillingSubmissionForAFEBSGResult/proceduresList/MedicalProcedureOutput' passing xmltype(a.response) columns
icpcID varchar2(50) path 'ipcdId') t1
/

        ID ICPCID
---------- --------------------------------------------------
         1 011801

或者你稍后展示的多个节点，他质疑这将 return:

        ID ICPCID
---------- --------------------------------------------------
         2 725013
         2 725105
