查詢XML表中插入SOAP XML內容

Question

您好我已經插入我的SOAP XML內容到表名爲foo後，但我有問題，查詢內容。

<?xml version="1.0" encoding="UTF-8" ?> 
- <ns:AccountQueryPage_Output xmlns:ns="urn:crmondemand/ws/ecbs/account/"> 
- <ListOfAccount xmlns="urn:/crmondemand/xml/Account/Data" lastpage="true"> 
- <Account> 
    <Id>CCC-TEST01</Id> 
    <AccountName>John Smith Pty Ltd</AccountName> 
    </Account> 
    </ListOfAccount> 
    </ns:AccountQueryPage_Output> 

我的查詢是

select xmltype(xml_response).extract('//AccountName/text()', 
             'xmlns:ns="urn:crmondemand/ws/ecbs/account/" ' || 
             'xmlns="urn:/crmondemand/xml/Account/Data').getStringVal() from Foo 

，我得到

ORA-31011: XML parsing failed 
ORA-19213: error occurred in XML processing at lines 2 
LPX-00209: PI names starting with XML are reserved 
ORA-06512: at "SYS.XMLTYPE", line 272 
ORA-06512: at line 1 
31011. 00000 - "XML parsing failed" 
*Cause: XML parser returned an error while trying to parse the document. 
*Action: Check if the document to be parsed is valid. 

任何幫助，以什麼即時做錯了什麼？

謝謝

功能EXTRACT和EXTRACTVALUE是在11g中deprecated。您應該嘗試使用XMLTABLE和XMLQUERY。

這裏是如何從XML檢索值。我爲您的XML添加了另一個測試帳戶，因此您知道這適用於多行。

WITH subq AS (SELECT XMLTYPE ('<?xml version="1.0" encoding="UTF-8" ?> 
<ns:AccountQueryPage_Output xmlns:ns="urn:crmondemand/ws/ecbs/account/"> 
<ListOfAccount xmlns="urn:/crmondemand/xml/Account/Data" lastpage="true"> 
<Account> 
    <Id>CCC-TEST01</Id> 
    <AccountName>John Smith Pty Ltd</AccountName> 
    </Account> 
    <Account> 
    <Id>CCC-TEST02</Id> 
    <AccountName>Test Pty Ltd</AccountName> 
    </Account> 
    </ListOfAccount> 
    </ns:AccountQueryPage_Output>') AS my_xml FROM DUAL) 
SELECT Acct_id, Acct_Name 
    FROM subq, 
     XMLTABLE (
      xmlnamespaces ('urn:crmondemand/ws/ecbs/account/' AS "ns", 
         DEFAULT 'urn:/crmondemand/xml/Account/Data'), 
      '/ns:AccountQueryPage_Output/ListOfAccount/Account' 
      PASSING subq.my_xml 
      COLUMNS Acct_ID VARCHAR2 (30) PATH 'Id', 
        Acct_Name VARCHAR2 (30) PATH 'AccountName');
