Hello, I have used Special:Export at en.wikipedia to export "Diabetes_mellitus" and ticked the box "include templates" (I'm only really after the templates). The resulting XML file is 40.1mb so I decided to go with mwdumper.js rather than Special:Import. I'm working on a fresh build of mediawiki on my local system. When running the command: java -jar mwdumper.jar --format=sql:1.5 Wikipedia-20090113203939.xml | mysql -u root -p wiki It is returning the following error: 1 pages (0.102/sec), 1,000 revs (102.062/sec) ERROR 1062 (23000) at line 99: Duplicate entry '45970' for key 1 Exception in thread "main" java.io.IOException: XML document structures must start and end within the same entity. at org.mediawiki.importer.XmlDumpReader.readDump(Unknown Source) at org.mediawiki.dumper.Dumper.main(Unknown Source) Caused by: org.xml.sax.SAXParseException: XML document structures must start and end within the same entity. 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.XMLScanner.reportFatalError(Unknown Source) at org .apache.xerces.impl.XMLDocumentFragmentScannerImpl.endEntity(Unknown Source) at org.apache.xerces.impl.XMLDocumentScannerImpl.endEntity(Unknown Source) at org.apache.xerces.impl.XMLEntityManager.endEntity(Unknown Source) at org.apache.xerces.impl.XMLEntityScanner.load(Unknown Source) at org.apache.xerces.impl.XMLEntityScanner.scanContent(Unknown Source) at org .apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanContent(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl $FragmentContentDispatcher.dispatch(Unknown Source) at org .apache .xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl.parse(Unknown Source) at javax.xml.parsers.SAXParser.parse(SAXParser.java:176) ... 2 more Can anyone please advise? After some googling the only advice I managed to find was: "Before you start, try clearing the tables that mwdumper works in: DELETE FROM page; DELETE FROM revision; DELETE FROM text; " I have done this and tried again, but the same error continues. Many thanks, Dawson
