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"> </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

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

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.

Can anyone offer me some suggestions? Thanks a lot. Sincerely Lusha

Re: [basex-talk] bulk-load
by Christian Grün 16 Jul '11

16 Jul '11

Dear Tomaso, dear Michael, today, I had a closer look into the BaseX routines that are responsible for adding new documents to the database, and I tweaked the update code of our document index to avoid linear costs for adding single documents. You are invited to check out the latest stable snapshot [1] and give us your valuable feedback. There are still some bottlenecks: - the default XML parser takes some time for initialization, which is particularly noticable for small documents. You'll get some performance boost by switching to the internal parser (Command: set intparse; see [2] for details). - as each BaseX database command is atomic, the data is flushed to disk after each update to avoid data loss. You may either specify a directory on disk to add multiple files at once, or choose to insert nodes instead of documents, which will give you better performance. Hope this helps, Christian [1] http://files.basex.org/releases/latest/basex-6.7.1-SNAPSHOT.jar [2] http://docs.basex.org/wiki/Parsers ___________________________ On Mon, Jul 4, 2011 at 8:22 PM, Christian Grün <christian.gruen(a)gmail.com> wrote: > Hi Tomaso, > >> From your answer I suppose there is something slower >> when Add() is called many times, and faster if we use CreateDb. >> Can you explain why the times increase?

how to specify xml-stylesheet when generating xml ?

Dear all at BaseX, how can one specify xml-stylesheet (for example in XQuery 3 prolog) ? I would like to add something like <?xml-stylesheet type="text/xsl" href="linktomystylesheet.xsl"?> between the xml declaration and the generated xml. I did not find any xml-stylesheet option for serialization.

Best approach for 10 million+ documents?
by Michael Paddon 14 Jul '11

14 Jul '11

Hi, I'm currently evaluating BaseX for a project. I've read all the online documentation but the underlying storage and indexing mechanisms are still a bit of a mystery to me, so I'm having trouble making optimal decisions in designing a large collection of documents. I have 10 million documents of moderate size. These are intended to be regularly replaced/updated. I have the choice of storing each document individually in a collection, or inserting/updating into a single document. Which approach will generally perform better? In an experiment, I found that after adding a few million documents, adding new documents got really slow. The JVM pegs at 100% CPU so it is doing a lot of work. What's going on here? Indexing? Would increasing the JVM memory help? Can indexing be disabled for bulk loads? Rather than try random things to see what worked, I was hoping to get some insight into how the system stores, indexes and uses resources. Many thanks, Michael

duplicated document in collection
by Craig Venter 14 Jul '11

14 Jul '11

Hello, I am trying BaseX 6.7 and have noticed that the same document can be added to a collection many times using the ADD command (add z.xml), duplicating data wich is not desirable. Is this a bug of this version? In comparison, using Sedna 3.4, the same document can not be added to a collection if it already exists, treating document names as primary key. Is there a solution to this, or is there a way in BaseX 6.7 to have a kind of primary key constraint? Thank you.

by Isidro Vila Verde 13 Jul '11

13 Jul '11

Dear All, I am trying to use xquery file:write function to create new documents but it seems only ADMIN users can do that. This is a little bit limited (IMHO) as I don't want to give admin privileges to my users. In other hand, it also seems incoherent as the user can add documents to data base directly from command line. > add as t.xml <r/> Path '/t.xml' added in 24.72 ms. > xquery declare namespace fx="http://expath.org/ns/file"; fx:write('file1.xml','<w/>') Stopped at line 1, column 78: [BASX0005] ADMIN permission needed. > xquery declare namespace fx="http://expath.org/ns/file"; fx:write('./file1.xml','<w/>') Stopped at line 1, column 80: [BASX0005] ADMIN permission needed. > xquery declare namespace fx="http://expath.org/ns/file"; fx:write('/f.xml','<w/>') Stopped at line 1, column 75: [BASX0005] ADMIN permission needed. > --------------------------------------------------------------------------------------------------------------------------------- I also try to give the user ADMIN privileges to the correspondent database but although it seems possible in the HELP, the fact is that it is not. > show users on test Username Read Write --------------------- test X X 1 Users. > help grant GRANT [NONE|READ|WRITE|CREATE|ADMIN] (ON [database]) TO [user] Grant user permissions. Grants permissions (on a database) to a user. > grant admin on test to test ADMIN permission is unknown. > grant create on test to test CREATE permission is unknown. > So, my question is: These are bugs, limitations, or some kind of wrong understood on my part?

by yoann maingon 12 Jul '11

12 Jul '11

Hi, I've seen the java code to create a new database. Is there a way i can create a new database from PHP? Will there be many people being able to use different databases at the same time on the same server? is it just a matter of hardware Server performance?
