Re: [basex-talk] SAX Serializer
by Michael.Hedenus-EXT＠continental-corporation.com 06 Feb '13

06 Feb '13

Dear Christian, thanx! That's fine for me. I wondered how expensive it might be to instantiate a Serializer. One problem remains: In SAXSerializer line 253 the initializiation of Attr is missing. This leads to NPE. Fix: private Atts decls = new Atts(); If there are more problems I'll be happy to report them to you :D Mit freundlichen Grüßen/Best regards Dr. Michael Hedenus Software Developer Powertrain Engine Systems CSW ETV RGB T2 PIXEL GmbH Im Gewerbepark C15, 93059 Regensburg, Germany Telefon/Phone: +49 941 790-6362 Telefax: +49 941 79013-90771 E-Mail: michael.hedenus-ext(a)continental-corporation.com www.continental-corporation.com ______________________________________________________________________ Continental Automotive GmbH, Siemensstr. 12, 93055 Regensburg, Germany Geschäftsführer/Managing Directors: Helmut Matschi, Gérard Cordonnier, Harald Stuhlmann Sitz der Gesellschaft/Registered office: Hannover Registergericht/Commercial registry: Hannover, HRB 59424, USt-Id.

SAX Serializer
by Michael.Hedenus-EXT＠continental-corporation.com 06 Feb '13

06 Feb '13

Dear Christian, it's very great that you've incorporated the SAXSerializer. But you've overdone it a bit. The setItem() method and the parse() methods are required. I've written a JUnit-Test to demonstrate the application of the SAXSerializer with JAXB. In line 49 there should be the method setItem, which you have removed. The JAXB unmarshaller is going to invoke parse(String) which now throws an exception with an 'unimplemented' note. So please re-enable the parse()-methods and re-introduce the setItem()-method. package basex.test.sax; import java.io.File; import javax.xml.bind.JAXBContext; import javax.xml.transform.Source; import javax.xml.transform.sax.SAXSource; import junit.framework.Assert; import org.basex.core.Context; import org.basex.core.cmd.CreateDB; import org.basex.io.serial.SAXSerializer; import org.basex.io.serial.Serializer; import org.basex.query.QueryProcessor; import org.basex.query.value.item.Item; import org.junit.Test; public class SAXSerializerTest { @Test public void unmarshallJAXBObjectWithSAXSerializer() throws Exception { File temp = getTemp(); JAXBContext jaxbContext = JAXBContext.newInstance (DomainObject.class); // create XML File input = new File(temp, "input.xml"); jaxbContext.createMarshaller().marshal(new DomainObject( "Object1", 42), input); // create DB System.setProperty("org.basex.path", temp.getAbsolutePath()); Context context = new Context(); new CreateDB("test1", input.getAbsolutePath()).execute(context); // get object from DB QueryProcessor queryProcessor = new QueryProcessor( "//domain-object[@name='Object1']", context); Item item1 = queryProcessor.iter().next(); // write out to see that item is here Serializer serializer1 = queryProcessor.getSerializer(System.out); serializer1.serialize(item1); serializer1.close(); SAXSerializer saxSerializer = new SAXSerializer(); SAXSource saxSource = new SAXSource(saxSerializer, null); // this is needed!!! saxSerializer.setItem(item1); DomainObject domainObject1 = jaxbContext.createUnmarshaller().unmarshal(saxSource, DomainObject.class ).getValue(); queryProcessor.close(); Assert.assertEquals(42, domainObject1.getValue()); } private File getTemp() { File temp = new File("d:/temp/basex"); //System.getProperty("java.io.tmpdir"); temp.mkdirs(); return temp; } } The code is attached to this mail.

BaseX as web application in servlet container
by marco fregonese 06 Feb '13

06 Feb '13

Hello, Is anyone there who can explain to me why in BaseX76.war (or previous versions) there are two WEB-INF directories each with a web.xml file inside? ~/BaseX76/WEB-INF/classes/WEB-INF/ Which web.xml file needs to be edited to configure BaseX as web application in Tomcat properly? Thanks. PS: I deployed BaseX75.war and 76 in Tomcat and they work after editing web.xml but I had to edit index.html and restxq.xqm as well to see style.css and basex.svg. Maybe it depends on my OS (Ubuntu) or my browser (Firefox), I don't know. Thank you.

Re: [basex-talk] Problem with DOM LS serialization
by Michael.Hedenus-EXT＠continental-corporation.com 06 Feb '13

06 Feb '13

Dear Christian, I've no idea why DOM/LS still doesn't work, but with the SAXSerializer the problem is no more. When the SAXSerialier works query result can easily converted into any DOM using a simple ContentHandler implementation: /** * Constructs a DOM from SAX events. * Original idea by Florent Georges. */ public class SaxToDomHandler implements ContentHandler { private final DocumentBuilder documentBuilder; private Document document; private Node current; public SaxToDomHandler(DocumentBuilder documentBuilder) { this.documentBuilder = documentBuilder; } /** * Returns the created document. */ public Document getDocument() { return document; } @Override public void startDocument() throws SAXException { document = documentBuilder.newDocument(); current = document; } @Override public void startElement(String uri, String name, String qName, Attributes attrs) { Element element = document.createElementNS(uri, qName); for (int i = 0; i < attrs.getLength(); i++) { String nsURI = attrs.getURI(i); String qname = attrs.getQName(i); String value = attrs.getValue(i); Attr attr = document.createAttributeNS(nsURI, qname); attr.setValue(value); element.setAttributeNodeNS(attr); } current.appendChild(element); current = element; } @Override public void endElement(String uri, String name, String qName) { current = current.getParentNode(); } @Override public void endDocument() throws SAXException { current = current.getOwnerDocument(); } @Override public void characters(char[] ch, int start, int length) { String string = new String(ch, start, length); current.appendChild(document.createTextNode(string)); } @Override public void ignorableWhitespace(char[] ch, int start, int length) { characters(ch, start, length); } @Override public void processingInstruction(String target, String data) { current.appendChild(document .createProcessingInstruction(target, data)); } @Override public void setDocumentLocator(Locator locator) { //NOP } @Override public void startPrefixMapping(String prefix, String uri) throws SAXException { //NOP } @Override public void endPrefixMapping(String prefix) throws SAXException { //NOP } @Override public void skippedEntity(String name) throws SAXException { //NOP } }

Xquery over all collections
by pw＠themail.co.uk 06 Feb '13

06 Feb '13

Hello List I am wanting to query all collections in BaseX 7.5 without hard coding the names of each collection in my xquery. I can list the collections with db:list() but am struggling to get something like let $r := (collection('A'), collection('B'), collection('C'))/xml/indicator[code='myCode'] I can use db:list() to get all documents in all collections in this way: let $q := for $a in (db:list()) let $e :=string-join( $a, ',') return $e let $z := for $x in $q return db:open($x) for $r in $z return $r Can anyone please suggest a way of using db:list and other functions in xquery to perform a query on all collections. Cheers Peter
