анализ XML-данных в oracle

Question

Я новичок в области XML оракула. Я пытаюсь разобрать XML, но не могу.

Ниже приведены данные XML.

Ниже запрос работает нормально, если CollectionItem существует только один раз внутри DataObjectElement. Если collectionItem появляется более одного раза, он терпит неудачу. В основном, что я пытаюсь достичь, рассматривайте данные в новой строке, когда он видит идентификатор TAG.

===================================== Ниже простой пример, который я ожидаю

Спасибо за ваш ценный ответ.

запрос, который вы опубликовали, работает нормально. но, как вы видите, есть несколько полей, которые генерируются NULL. например. 1-й DataObjectElement содержит 2 CollectionItem (604008,604008a), но в CollectionItem нет «SystemName», поэтому я ожидаю SystemName из основного тега DataObjectElement .. который является «AccountRelationship». же идет к OBJECTTYPE

WITH t AS (SELECT XMLType('<CompositeDataObject Type="ApplicantsAAT" Version="0"> 
<DataObjectElement SystemName="AccountRelationship" ObjectType="DataObjectCollection"> 
<CollectionItem ID="604008" EncryptedID="4GnX1!b8epwsAmwbfvZjo;xAAAAAB6r2wy" DataObjectCategory="RepeatingAttribute" DataObjectType="AccountRelationshipAAT"/> 
<CollectionItem ID="604008a" EncryptedID="4GnX1!b8epwsAmwbfvZjo;xAAAAAB6r2wy" DataObjectCategory="RepeatingAttribute" DataObjectType="AccountRelationshipAAT"/> 
</DataObjectElement> 
<DataObjectElement SystemName="ApplicantCreditRefDetailsAATSL" ObjectType="DataObject" ID="603979" EncryptedID="4PPEFaEyt2Q!K48f13wy7gzAAAAAB6r2wR" DataObjectCategory="RepeatingAttribute" DataObjectType="ApplicantCreditRefDetailsAATSL"/> 
<CompositeDataObjectElement SystemName="Tabs" ObjectType="DataObject" ID="378409" EncryptedID="4J!pTqS7x4XxIYZjRd2jA2UAAAAAB6o51z" CompositeDataObject="ApplicantsViewsAAT"/> 
</CompositeDataObject>') xmlcol 
       FROM dual) 

       SELECT extractvalue(value(x), '/*/@ID') id, 
       extractvalue(value(x), '/*/@EncryptedID') EncryptedID, 
       extractvalue(value(x), '/*/@SystemName') SystemName, 
       extractvalue(value(x), '/*/@DataObjectCategory') DataObjectCategory, 
       extractvalue(value(x), '/*/@ObjectType') ObjectType, 
       extractvalue(value(x), '/*/@DataObjectType') DataObjectType, 
       extractvalue(value(x), '/*/@CompositeDataObject') CompositeDataObject 
     FROM t, TABLE(XMLSequence(extract(t.xmlcol,'//*[@ID]'))) x; 

В результате из приведенного выше запроса

ID  ENCRYPTEDID       SYSTEMNAME      DATAOBJECTCATEGORY OBJECTTYPE    DATAOBJECTTYPE     COMPOSITEDATAOBJECT 
604008 4GnX1!b8epwsAmwbfvZjo;xAAAAAB6r2wy         RepeatingAttribute       AccountRelationshipAAT 
604008a 4GnX1!b8epwsAmwbfvZjo;xAAAAAB6r2wy         RepeatingAttribute       AccountRelationshipAAT

только небольшое изменение я жду это (ниже результата содержит значение для SystemName И OBJECTTYPE)

ID  ENCRYPTEDID       SYSTEMNAME      DATAOBJECTCATEGORY OBJECTTYPE    DATAOBJECTTYPE     COMPOSITEDATAOBJECT

im не совсем уверен, что вы после, но это 1 строка на «id»? если да ..

10 select id, EncryptedID, 
11   nvl(SystemName, extractvalue(xmlcol, '//*[child::*/@ID="' || id || '"]/@SystemName')) SystemName, 
12   DataObjectCategory, 
13   nvl(ObjectType, extractvalue(xmlcol, '//*[child::*/@ID="' || id || '"]/@ObjectType')) ObjectType, 
14   DataObjectType, 
15   CompositeDataObject 
16 from (SELECT t.xmlcol, extractvalue(value(x), '/*/@ID') id, 
17     extractvalue(value(x), '/*/@EncryptedID') EncryptedID, 
18     extractvalue(value(x), '/*/@SystemName') SystemName, 
19     extractvalue(value(x), '/*/@DataObjectCategory') DataObjectCategory, 
20     extractvalue(value(x), '/*/@ObjectType') ObjectType, 
21     extractvalue(value(x), '/*/@DataObjectType') DataObjectType, 
22     extractvalue(value(x), '/*/@CompositeDataObject') CompositeDataObject 
23   FROM t, TABLE(XMLSequence(extract(t.xmlcol,'//*[@ID]'))) x)
