Dear all, just four weeks have passed, and we are proud to announce Version 6.7.1 (a.k.a. The Balisage 2011 Edition) of BaseX. Here is what you get: XQuery: - New database functions for adding, deleting, renaming and replacing documents, and optimizing databases: http://docs.basex.org/wiki/Database_Functions - XSLT transformations via Java or Saxon: http://docs.basex.org/wiki/XSLT_Functions - All XQuery 3.0 functions are now supported: http://docs.basex.org/wiki/XQuery_3.0 - Tail-call optimizations to speed up recursive functions Storage: - Use ADDARCHIVES to parse files within archives - Use SKIPCORRUPT to skip non-well-formed files when creating a database: http://docs.basex.org/wiki/Options - Max. level depth limit (256) removed - The document index is now incrementally updated GUI: - "Manage Database" dialog now supports operations on multiple databases and the command-line glob syntax: http://docs.basex.org/wiki/Commands#Glob_Syntax - Drag and drop operations introduced for opening new files and copying file paths Client/Server: - Delay clients that repeatedly fail to login - All remaining plain-text password operations now use MD5 to send and log passwords More details are found on our homepage [1], in GitHub [2] and on our basex-talk mailing list [3].

help like JAXP in BaseX ?
by Burkert, Michael 25 Jul '11

25 Jul '11

Hello ! We want to fill a JTree with xquery-result, like <A attr="a1"> <B attr="b1"> </B> </A> This returns lines: ResourceSet set = service.query(QUERY); ResourceIterator iter = set.getIterator(); while(iter.hasMoreResources()) { Resource res = iter.nextResource(); System.out.println(res.getContent()); } This returns the XML-structure: DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(true); DocumentBuilder builder = null; Document doc = null; try { builder = factory.newDocumentBuilder(); doc = builder.parse(XMLFile); } catch (xx) NodeList nodeList = doc.getChildNodes(); I need something like NodeList (JAXP), to iterate through xml-structure. How to do this with BaseX ? With best regards Michael

Embedding BaseX jax-rx inside a war
by Donovan, Aaron [USA] 22 Jul '11

22 Jul '11

First off, this is my first week with BaseX, and I'm extremely pleased with both performance and ease of use. Thank you. I really like the interface provided by jax-rx, but I want to deploy it inside of a war rather than start a separate server. While I considered starting the basex server in ServletContextListener, I noticed that LocalSession now supports all of the operations of ClientSession. I was hoping that you'd consider making the jax-rx's selection of LocalSession or ClientSession based upon a system property. The first patch above changes references to ClientSession and LocalQuery to Session and Query respectively in BXOutput and BXJaxRX. You should be able to apply it without any concerns. The second patch introduces a SessionFactory that is used by BXCode to create Sessions appropriately. It worked for me, but as I said this is my first week with the tool. There might be side effects that I didn't intend or a better place to introduce this functionality. Any time frame on releasing a 6.7.1 that includes your full LocalSession implementation? Thanks, Aaron

XQuery direkt auf XMLFile ?
by Burkert, Michael 22 Jul '11

22 Jul '11

Hallo ! Gibt es eine einfache Möglichkeit, das Ergebnis einer XQuery-Abfrage wiederum mit XQuery abzufragen ? Wenn ich es richtig verstehe, müsste dazu das Ergebnis (xml) zuvor in die Datenbank geschrieben werden. Derzeit schreibe ich das Ergebnis in ein XML-File und würde mir gerne dieses File direkt schnappen für weitere Abfragen. Sollte dies möglich sein, habt Ihr Codebeispiele auf Eurer Seite, bzw. wie sähe so etwas aus ? Mögliche Stichworte die dazu zu finden sind: XMLStreamWrapper, parse, XMLSerializer Mit freundlichem Gruß Michael

about basex server
by Lusha Wang 21 Jul '11

21 Jul '11

Hi Everyone If i have a dataset that is 1mb, what kind of computer is required to run the basex server? How about 1gb? I feel like the basex server cannot handle very frequent database query. Sincerely Serena

Re: [basex-talk] about performance

I got your example working after closing one element in your example document. Still I couldn't reproduce the problem you encountered. Note, however, that you are calling " $query->more() " twice without retrieving the first result. If your problem persists, please try to run your code with the stable version of BaseX (http://files.basex.org/releases/latest/), and give us some more hints.
