當我嘗試解析XML文檔時,我在這裏遇到了XPath屬性的小問題。 這是我的例子:如何在Oracle中通過xmltype解析XML
DECLARE
px_return XMLTYPE
:= XMLTYPE (
'<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP:Header xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
<h:AxisValues xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:h="urn:/microsoft/multichannelframework/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:/microsoft/multichannelframework/">
<User xmlns="">FSCD</User>
<Solution xmlns="">Multicare</Solution>
<ApplicationalUser xmlns=""/>
<ApplicationalUserSystem xmlns=""/>
<SystemUser xmlns=""/>
<SystemUserSystem xmlns=""/>
<Proxy xmlns="">0</Proxy>
</h:AxisValues>
</SOAP:Header>
<SOAP:Body xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
<ns1:maintainMandateResponse xmlns:ns1="urn:enterprise.com/ws/SAP/Finantial/MaintainMandate/V1">
<return>
<messageType>E</messageType>
</return>
</ns1:maintainMandateResponse>
</SOAP:Body>
</soapenv:Envelope>');
lv_msgType VARCHAR2 (20);
BEGIN
SELECT Return.msgType
INTO lv_msgType
FROM XMLTABLE (
xmlnamespaces (
DEFAULT 'enterprise.com/ws/SAP/Finantial/MaintainMandate/V1',
'http://schemas.xmlsoap.org/soap/envelope/' AS "soapenv",
'http://schemas.xmlsoap.org/soap/envelope/' AS "SOAP",
'enterprise.com/ws/SAP/Finantial/MaintainMandate/V1' AS "ns1"),
'//soapenv:Envelope/SOAP:Body/ns1:maintainMandateResponse'
PASSING px_return
COLUMNS msgType VARCHAR2 (1) PATH 'messageType') Return;
DBMS_OUTPUT.put_line ('Message type: ' || lv_msgType);
END;
我得到一個NO_DATA_FOUND異常,因爲我無法找到在此分析方法的結果。
我已經嘗試了很多不同的策略,包括將return
放在PATH或XQUery字符串中,但沒有成功。
我認爲這是一個小而簡單的問題,但我無法找到。 在此先感謝! Filipe
感謝亞歷克斯。這顯然是一個小路徑問題。 – milheiros
