Problems with XML DB api
by Jiří Kadlec 08 Mar '10

08 Mar '10

Hi, I'm having a problem with XML DB, when I'm trying to access result as DOM. I'm using this code sequence: if (res instanceof XMLResource){ XMLResource resource = (XMLResource) res; Node node = resource.getContentAsDOM(); System.out.println("Get content: " + resource.getContent()); System.out.println("Node je: " + node.getNodeName()); } everytihng goes ok, when i use resource.getContent(), i got expected results but when I try to use resource.getContetAsDOM() a got following exception: Exception in thread "main" java.lang.NullPointerException at org.basex.query.item.DBNode.<init>(DBNode.java:50) at org.basex.api.xmldb.BXXMLResource.getContentAsDOM(BXXMLResource.java:144) at testmxquery.XQueryDatabaseSample.main(XQueryDatabaseSample.java:186) Java Result: 1 I'm using modified example from your web site. Thanks for your help Jiri

Problems with function transormation function put and namespaces
by Jiří Kadlec 08 Mar '10

08 Mar '10

Hi Guys, I'm have problems with BASE-X and namespaces when I'm using put function for e.g declare namespace bk := "http://acision.com.uri"; put( copy $nn := doc('D:/tstxml.xml') modify insert node <x/> into $nn/site/region/bk:africa return $nn, 'D:/tstxml.xml') start of the tstxml.xml look like this <site xmlns:bk="http://acision.com.uri"> <regions> <bk:africa> I found out that when I use this the same query without specifying namespace it inserts element <x/> into bk:africa but it changes the document and it looks like: <site > <regions> <bk:africa xmlns:bk="http://acision.com.uri"> .... ... </x> </bk:africa> Is this a bug or am I doing something wrong? I need to use namespace prefix in put function is it possible or it's not supported by BASE-X at all? Thank for help Jiri

After further testing, the problem appears to be in a different place than I originally thought. Therefore please disregard my previous post.

Dear Ms Chantola, if you want to dig in more deeply, you should have a look at the Data class. It offers basic methods for accessing the size, distance, parent, etc. for a specified pre value. Some additional information on the storage is given at the top of the class: https://svn.uni-konstanz.de/dbis/basex/trunk/basex/src/main/java/org/basex/… Our current documentation on the internals is the source code; I'm sorry we have no additional publications available, but you are invited to check out some of our lecture slides: http://www.inf.uni-konstanz.de/dbis/teaching/ws0708/dbissem/BaseXInside.pdf http://www.inf.uni-konstanz.de/dbis/teaching/ws0708/xml/24-Native.pdf Feel free to ask for more, Christian On Thu, Mar 4, 2010 at 12:29 PM, Chantola Kit <kchantola(a)kde.cs.tsukuba.ac.jp> wrote: > Dear Mr./Ms. Christian: > > Thank you very much for your reply. > "info table" works for table dump.

adding document (as string) to collection
by Travis Webb 02 Mar '10

02 Mar '10

Everyone, Here's my situation: I'm using XQJ. I have an xml document stored as a java string, and I want to store this into an xquery collection. I see no way to do this without using the BaseX-specific libraries. I've looked everywhere, and the only thing I've found that's close is MonetDB's add-doc() function, but that takes a url as an argument, not a string. I want to do something like: insert node $document into collection("test"). Obviously this doesn't work because collections are sequences. Any info is appreciated. -tjw

Stored procedures (XRPC) support
by Harmen Wessels 24 Feb '10

24 Feb '10

I am currently working on a research project on native XML databases and I am trying some stuff on BaseX and I must complement on the nice GUI supplied with the database. After testing some stuff I now have a question: is there support for stored procedures in some sort for BaseX? I would like to query the database using a XQuery which is stores in the database and can be called using some parameters. Thanks. Regards, Harmen Wessels.
