Losing part of document name when renaming directory
by Ketill Fenne 26 May '15

26 May '15

Hi! I am running BaseX 8.1. This is my test case: create database test add to /doc/title/version=1 c:/temp/xml.xml Running query: *for $doc in (collection('test')) return (base-uri($doc))* Result: *test/doc/title/version=1* Executing this command: *rename /doc/title/ /doc/title2/* Running query once again: for $doc in (collection('test')) return (base-uri($doc)) Result: *test/doc/title2/ersion=1* So, I am losing the "v" in version, that is the first letter after the directory that is renamed, seems to disappear with each rename. A bug, or improper usage? Kind regards Ketill Fenne

db:event
by Marco Lettere 26 May '15

26 May '15

Hi Christian, I read that starting with 8.2 the db:event API has been removed and will be replaced by triggers. Since we wanted to start using db:event in order to chain activities in our workflows in a loosely coupled way, I'd like to know when the new feature based on triggers will be available. Are there any hints on how the API will possibly look? Will it be possible to fire explicit applicative events not only based on db activities? Thanks. BR, Marco.

JTattoo's themes not recognized.
by Alex R. Loayza 26 May '15

26 May '15

Hello, To use the dark themes for the GUI mentioned in http://docs.basex.org/wiki/Graphical_User_Interface#Look_and_Feels, I downloaded JTattoo-1.6.11.jar and placed it in BaseX/lib. Upon restarting the GUI, I go to Options/Preferences/Visualization/Look & Feel, where I expect to see the additional themes provided by JTattoo. However, none of them show up in the drop-down menu. Is there something else I need to do? Thank you very much! Alex

Multiple server instances on a single computer?
by France Baril 25 May '15

25 May '15

Hi, Is it possible to install BaseX instances on the same computer? My goal is to be able to work on multiple client projects, each with their own server settings (ex. separate .basex files), dbs and .xqm without having to create a VM for each. VMs are heavy to run on my laptop, and context switching takes time. Thanks, France -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Re: [basex-talk] "Input is too large for a single database" error

Hi Huib, > However, using 8.2 I managed to load the entire Dutch legislation documents > into 5 separate databases. Yay! Good to hear! > Anyway, and I must confess I am a bit lazy here, how do I run a query over > multiple databases/collections in BaseX? Of course I would like to run the > same dumb count query in BaseX too, over these 5 databases containing all my > data, see if it works... This could be a solution: count( for $name in ('laws1', 'laws2') return db:open($name)//law ) This could be another: count( for $i in 1 to 5 let $name := 'laws' || $i return db:open($name)//law ) This is a third (it may be the fastest one, because the dynamic binding of database names in the first 2 queries prevents some optimizations to be triggered): sum( for $i in 1 to 5 let $query := 'count(db:open("db' || $i || '")//law)' return xquery:eval($query) ) Hope this helps, Christian

Position of matched tokens in a full-text query
by Javier Couto 22 May '15

22 May '15

Hi, Sorry if this is too basic, but I’m trying to get the positions of the matched tokens in a full-text query, and I can’t find the way to do it. I imagine something like: for $sentence in //sentence where $sentence[text() contains text { ‘DNA', ‘oxidation' }] return <positions>ft:SOME-FUNCTION-FOR-TOKENS-POSITIONS($sentence[text() contains text { ‘DNA', ‘oxidation' }])</positions> Is this possible? Thank you in advance, Javier

[DELIVER]Request for Training
by Adam Law 22 May '15

22 May '15

I was wondering whether there might be someone on the list who would be willing to teach me about BaseX. I will pay per hour. I have some xquery code (from existdb) that I scrapped together and would like to improve and set up a similar app in BaseX. I have other applications that I would like to have coded. If you are interested, please let me know your hourly rate. I am a sole trader and would find some training invaluable. I have limited xquery and xslt experience. Kind regards Adam

Installing an older version of BaseX on a Mac laptop
by Schwartz, Christine 22 May '15

22 May '15

Hi, I'm new to BaseX and currently preparing a training session teaching XQuery and using BaseX as the programming environment. I'm setting up step-by-step instructions for the attendees and have run into trouble with the Mac installation using Homebrew and BaseX. The Homebrew formula that was available yesterday appears to be gone. Please advise as to how to simply install BaseX on a Mac, as the session is for non-programmers and I want to keep the instructions simple. Thanks, Chris Christine Schwartz Metadata Librarian and XML Database Administrator Princeton Theological Seminary Library

db:replace and error bxerr:BXDB0007 (opened by another process)
by James Ball 21 May '15

21 May '15

Hello, I’m currently writing a small RESTXQ application that receives POSTed XML and then stores it into the database. It works well but I want to make it more robust so I’m adding more error handling code. One scenario I want to cover is where the database to be written to exists but is open in another process for some reason. In my function I do something like this: try { db:replace(“DATABASE_NAME”,”PATH/TO/FILE”,<Element/>) } catch * { db:output(<insert code here>) } I expect that this code should complete without error - knowing of course that the database won’t be updated. Instead I always get a bxerr:BXDB0007 error thrown and I can’t find any way to catch it. (It’s also not listed as a possible error in the documentation, although is against db:create) Is this something subtle to do with the pending updates list? I’m sure I’m missing something obvious but I can’t see it. Thank you for any help and direction, James
