BaseX produces illegal XML
by Godmar Back 15 Feb '11

15 Feb '11

BaseX 6.5.1 *still* has issues with producing illegal XML. See http://top.cs.vt.edu/~gback/bx/b651-bug/ for a snapshot of the BaseXData directory with instructions on how to reproduce it. BaseX returns: <entry xmlns="http://libx.org/xml/libx2" xmlns="http://www.w3.org/2005/Atom"> which obviously is invalid XML. - Godmar

Different default encodings based on output param's media-type

Hi, I have noted that: http://localhost:8984/basex/jax-rx?wrap=no&query=%3Cdata%3E%C3%A4%3C/data%3… leads to <data>ä</data> http://localhost:8984/basex/jax-rx?wrap=no&query=%3Cdata%3E%C3%A4%3C/data%3… leads to <data>�</data> http://localhost:8984/basex/jax-rx?wrap=no&query=%3Cdata%3E%C3%A4%3C/data%3… leads to <data>ä</data> http://localhost:8984/basex/jax-rx?wrap=no&query=%3Cdata%3E%C3%A4%3C/data%3… leads to <data>Ã¤</data> Does this mean that for text/plain, the query submitted is assumed to be in iso-8859-1 and for text/xml, it is assumed to be in utf-8? If so, why different treatment? Thanks.

Re: [basex-talk] Probably a bug: replace value of node
by Lukas Kircher 14 Feb '11

14 Feb '11

Hi Artur, I just found out this all comes down to a mistake in our XQuery Update documentation - I'm sorry to cause that confusion. The XQuery Update specification says this: If you have an expression like ... *'replace value of node A with B'* the expression *B* is evaluated with a text node constructor. That means the result of *B *is either a sequence of text nodes or an empty sequence. Considering your example the outcome is valid - it's the documentation which is wrong. It's simply not possible to replace the *value of* an element node (its descendants) with other elements. I'll take care of this inconsistency. Hope this clears things up, thanks for pointing that out!

Wish - allow using clipboard also for shift+Delete control+Insert shift+Insert
by Jan Vlčinský (CAD) 14 Feb '11

14 Feb '11

Hi Working in GUI is nice, I only like using shift+Delete control+Insert shift+Insert shortcuts for working with clipboard and currently it does not work in XQuery window in BaseX GUI See http://en.wikipedia.org/wiki/Cut,_copy,_and_paste#Common_keyboard_shortcuts I am working on MS Windows. You see, I do care about your wish list not to let it empty for too long time "-). Best reagards Jan Vlčinský -- *Ing.

BaseX6.5 - how to add documents into collection over wire (probably using ADD command)
by Jan Vlčinský (CAD) 14 Feb '11

14 Feb '11

Hi I need to insert documents into BaseX collection. As data are not always available directly as files and as sometime my server is remote to me, I need a method to add documents remotely. With older BaseX (I think BaseX 6.4) I was able to use add commend in the way add as doc1 <root/> This works now. But I am unable to insert anything, what has any attribute in this manner add as doc1 <root att="att"/> This keeps complaining and prints back help on the console. I am using basexclient.bat and Python API. What am I doing wrong? Thanks for any advice. Jan

Probably a bug: replace value of node
by Artur Moor 14 Feb '11

14 Feb '11

Hi all, following the documentation on http://docs.basex.org/wiki/Update the instruction of: replace value of node /doc with <new-element/> on db: <doc> <node/> </doc> should result in: <doc> <new-element/> </doc> but the result is: <doc/>

Maven Repository
by Christian Grün 11 Feb '11

11 Feb '11

Hi there, to all of you working with Maven: we've just moved our Maven repository to the basex.org domain. The new address is: http://files.basex.org/maven We've also updated the Maven artifacts in our documentation: http://docs.basex.org/wiki/Maven Next, we're currently working on automating the Maven deployment to guarantee that the latest snapshots can be integrated in your projects as well. And, last but not least, BaseX will soon be available via Debian and APT.

data corruption
by e.e.h.lastdrager＠student.utwente.nl 10 Feb '11

Hello, Unfortunately I am unable to use BaseX (6.5) as I keep getting data corruption. I run BaseX on a dedicated server. The xml-datafiles I insert into the database have the following layout: <EEGData bla="x" > <signal name="x"> <timeslot start="2008-07-24T14:22:16">-53.2942688282 -37.5091841347 -35.6337285276 (many more values)</timeslot>  </signal>  </EEGData> Running "list" on the client returns the following: Name Documents Size Path ------------------------------------------------------------------------ ------------------ fullxml 3789 522153128560 /path/to/xml This database was created by running the command: java -cp basex.jar org.basex.BaseXClient -c "create db fullxml /path/to/xml/files/" The problems start when I execute the "list fullxml" command, this returns: > list fullxml Possible bug?

I even dropped the entire database and recreated it, with the same problem on the same file(s). It seems that after a certain amount of data, the database gets corrupted; all documents inserted after this point contain garbage. I also tried to create the database with "intparse" set to ON, but I get the same problem. Regards, Elmer
