Hi to all, I'm new to digester and I have the following problem:
I have such an XML File to parse: <?xml version='1.0' encoding='UTF-8'?> <OAI-PMH xmlns='http://www.openarchives.org/OAI/2.0/' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://www.openarchives.org/OAI/2.0/ http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd'> <responseDate>2009-03-12T14:00:14Z</responseDate> <request verb="ListRecords" metadataPrefix="oai_dc" set="2009">http://url.url.org/abc.asp</request> <ListRecords> <record> <header> <identifier>oai:oai.ethz.ch:e-collection/005583701</identifier> <datestamp>2008-12-08</datestamp> <setSpec>2009</setSpec> </header> <metadata> <oai_dc:dc xsi:schemaLocation="http://www.openarchives.org/OAI/2.0/oai_dc/ http://www.openarchives.org/OAI/2.0/oai_dc.xsd"; xmlns="http://purl.org/dc/elements/1.1/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:oai_dc="http://www.openarchives.org/OAI/2.0/oai_dc/";> <title>Universita?res Wissen teilen Forschende im Dialog </title> <creator>Ru?egger, Hans-Ulrich </creator> <type>text</type> <publisher>Zu?richvdf Hochschulverlag an der ETH Zu?rich</publisher> <date>2009</date> <language>ger</language> <subject>Wissenschaft</subject> <subject>Forschung</subject> <subject>Kooperation</subject> <subject>Wissenstransfer</subject> <identifier>http://url.url.url.org/blabla</identifier> <identifier>http://url.url.url.org/blabla.pdf</identifier> <identifier></identifier> </oai_dc:dc> </metadata> </record> ...other records </ListRecords> </OAI-PMH> Then I wrote my parser: ... public ListRecordsParser(InputStream response) throws IOException, SAXException { // instantiate Digester and disable XML validation Digester digester = new Digester(); digester.setValidating(false); // instantiate ListRecords class digester.addObjectCreate("OAI-PMH/ListRecords", ListRecords.class ); // instantiate Record class digester.addObjectCreate("OAI-PMH/ListRecords/record", Record.class ); // instantiate Header class digester.addObjectCreate("OAI-PMH/ListRecords/record/header", Header.class ); digester.addBeanPropertySetter( "OAI-PMH/ListRecords/record/header/identifier", "identifier" ); digester.addBeanPropertySetter( "OAI-PMH/ListRecords/record/header/datestamp", "datestamp" ); digester.addBeanPropertySetter( "OAI-PMH/ListRecords/record/header/setSpec", "setSpec" ); digester.addSetNext( "OAI-PMH/ListRecords/record", "setHeader" ); // instantiate MetaData class digester.addObjectCreate("OAI-PMH/ListRecords/record/metadata", MetaData.class ); digester.addBeanPropertySetter( "OAI-PMH/ListRecords/record/metadata/title", "title" ); digester.addBeanPropertySetter( "OAI-PMH/ListRecords/record/metadata/creator", "creator" ); digester.addBeanPropertySetter( "OAI-PMH/ListRecords/record/metadata/publisher", "publisher" ); digester.addSetNext( "OAI-PMH/ListRecords/record", "setMetaData" ); digester.addSetNext( "OAI-PMH/ListRecords/record", "addRecord" ); // now that rules and actions are configured, start the parsing process ListRecords lr = (ListRecords)digester.parse(response); ... The problem is that when I run it I get: 2009-03-12 16:01:41,431 [main] ERROR org.apache.commons.digester.Digester(org.apache.commons.digester.Digester.fatalError(Digester.java:1765)) - Parse Fatal Error at line -1 column -1: Premature end of file. org.xml.sax.SAXParseException: Premature end of file. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at org.apache.xerces.util.ErrorHandlerWrapper.fatalError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLVersionDetector.determineDocVersion(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.commons.digester.Digester.parse(Digester.java:1887) at ethz.oai.helper.ListRecordsParser.<init>(ListRecordsParser.java:59) at ethz.oai.MetaDataCollector.getDocumentsData(MetaDataCollector.java:129) at ethz.test.MetaDataCollectorTest.testGetMetaData(MetaDataCollectorTest.java:57) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.internal.runners.TestMethodRunner.executeMethodBody(TestMethodRunner.java:99) at org.junit.internal.runners.TestMethodRunner.runUnprotected(TestMethodRunner.java:81) at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:34) at org.junit.internal.runners.TestMethodRunner.runMethod(TestMethodRunner.java:75) at org.junit.internal.runners.TestMethodRunner.run(TestMethodRunner.java:45) at org.junit.internal.runners.TestClassMethodsRunner.invokeTestMethod(TestClassMethodsRunner.java:66) at org.junit.internal.runners.TestClassMethodsRunner.run(TestClassMethodsRunner.java:35) at org.junit.internal.runners.TestClassRunner$1.runUnprotected(TestClassRunner.java:42) at org.junit.internal.runners.BeforeAndAfterRunner.runProtected(BeforeAndAfterRunner.java:34) at org.junit.internal.runners.TestClassRunner.run(TestClassRunner.java:52) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:45) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) What's the problem? Shoul I define the entire XML structure in my parser?
