James Couball commented on XMLBEANS-199: ---------------------------------------- Here is the original email from the xml beans user list the prompted me to write this ticket: Subject: RE: Problem Using changeType On execQuery Result From: Yana Kadiyska <[EMAIL PROTECTED]> Date: Monday, September 12, 2005 18:31:11 To: user@xmlbeans.apache.org; James Couball <[EMAIL PROTECTED]> Hi James, changeType only works successfully if AddressType is a document type. Currently, there is no way to type an XQuery result if the type of the element returned is not a document type. It's obviously a serious limitation and we're aware of it...you can open a bug in Jira for tracking purposes. -----Original Message----- From: James Couball [mailto:[EMAIL PROTECTED] Sent: Monday, September 12, 2005 5:38 PM To: user@xmlbeans.apache.org Subject: Problem Using changeType On execQuery Result I am trying to read the result of an execQuery. My xml document (give at the end of this email) gives test data (namely what accounts are used for each test). I have written an xquery expression to figure out the account ids to use for each test. Here is the code I am trying to get to work: TestDataDocument testDataDocument = TestDataDocument.Factory.parse(new File("aws-test-data.xml")); String queryExpression = "declare namespace aws='http://test.aws.couball/data'; "+ "for $a in /aws:test-data/aws:tests/aws:[EMAIL PROTECTED]'Test1']/aws:accountref/@name "+ "return /aws:test-data/aws:accounts/aws:[EMAIL PROTECTED]"; XmlObject[] xmlObjects = (XmlObject[]) testDataDocument.execQuery(queryExpression); log.debug("xmlObjects.length="+xmlObjects.length); for (XmlObject xmlObject : xmlObjects) { log.debug(xmlObject.getClass().getName()); AccountType account = (AccountType) xmlObject.changeType(AccountType.type); log.debug(account.getClass().getName()); log.debug("account.getId()="+account.getId()+", account.getName()="+account.getName()); } I believe that I am getting the right data selected in the xquery expression since I can use a cursor from each xmlObject and traverse to see all the nodes I expect. The problem is with utilizing changeType. The account object in my sample always returns null for getId() and getName(). AccountType is a generated xmlbeans object from my schema. Am I missing something here with .changeType? Or am I on the wrong track. Any advice would be appreciated. Here is the log output I receive when running this snippet: 2005-09-12 17:30:35,785 [main] DEBUG couball.aws.test.CheckCategoriesTest - xmlObjects.length=2 2005-09-12 17:30:35,785 [main] DEBUG couball.aws.test.CheckCategoriesTest - xmlObject.getClass().getName()=org.apache.xmlbeans.impl.values.XmlAnyTypeImpl 2005-09-12 17:30:35,785 [main] DEBUG couball.aws.test.CheckCategoriesTest - account.getClass().getName()=couball.aws.test.data.impl.AccountTypeImpl 2005-09-12 17:30:35,785 [main] DEBUG couball.aws.test.CheckCategoriesTest - account.getId()=null, account.getName()=null 2005-09-12 17:30:35,785 [main] DEBUG couball.aws.test.CheckCategoriesTest - xmlObject.getClass().getName()=org.apache.xmlbeans.impl.values.XmlAnyTypeImpl 2005-09-12 17:30:35,785 [main] DEBUG couball.aws.test.CheckCategoriesTest - account.getClass().getName()=couball.aws.test.data.impl.AccountTypeImpl 2005-09-12 17:30:35,785 [main] DEBUG couball.aws.test.CheckCategoriesTest - account.getId()=null, account.getName()=null The XML: <?xml version="1.0" encoding="UTF-8"?> <tests> <test name="Test1"> <accountref name="Account1"/> <accountref name="Account2"/> </test> <test name="Test2"> <accountref name="Account2"/> <accountref name="Account4"/> </test> <test name="Test4"> <accountref name="Account6"/> <accountref name="Account7"/> <accountref name="Account8"/> <accountref name="Account9"/> </test> <test name="Test4"/> <test name="Test5"/> </tests> <accounts> <account name="Account1" id="19a2921138"/> <account name="Account2" id="1142344365"/> <account name="Account3" id="16r5y73980"/> <account name="Account4" id="36fdf57a70"/> <account name="Account5" id="1940594337"/> <account name="Account6" id="387a77fda4"/> <account name="Account7" id="02300s7168"/> <account name="Account8" id="11k0131113"/> <account name="Account9" id="252594ae50"/> </accounts> </test-data> > Make XmlObject.changeType Work For non-document Types > ----------------------------------------------------- > > Key: XMLBEANS-199 > URL: http://issues.apache.org/jira/browse/XMLBEANS-199 > Project: XMLBeans > Type: Bug > Components: XmlObject > Versions: Version 2 > Environment: N/A > Reporter: James Couball > > Currently, XmlObject.changeType only works if the object it is performed on > is a document type.
