Fulltext index not applied
by Sebastian Zimmer 16 Nov '18

16 Nov '18

Hi, I'm working on a query where the full-text index is not applied, even though it could be (see attached test.xql). I'm sorry for the somewhat complicated look of the example with data-specific XPaths and so on. I really have tried to simplify it as much as I could, but when I further simplify it, the fulltext index actually will be applied or the query is optimized to () due to cached evaluations. But if you take the expression of the variable $number and inline it into below where the variable is referenced, you may see what I mean. The result is an equivalent query (see attached test-ft.xql) to the original one, but now the fulltext index *is* applied. I'm using the BaseX 9.1 snapshot from 2018-11-05. Best, Sebastian -- Sebastian Zimmer sebastian.zimmer(a)uni-koeln.de <mailto:sebastian.zimmer@uni-koeln.de> CCeH Logo <http://cceh.uni-koeln.de> Cologne Center for eHumanities <http://cceh.uni-koeln.de> DH Center at the University of Cologne Twitter Logo <https://twitter.com/CCeHum>@CCeHum <https://twitter.com/CCeHum>

BaseX on Eclipse OpenJ9?
by vincent van der leun 16 Nov '18

16 Nov '18

Hello, I've been reading for quite some time. Some time back, I was looking for a way to play with XQuery and came across BaseX database system. Being intrigued, I've been following its development since. I found a use-case for a personal web application, which will be querying BaseX for documents stored in XML. A scheduled cron task will be adding new documents to the database from time to time. At the moment my default JVM is Eclipse OpenJ9 (previously IBM J9), based on OpenJDK 8, as it's promising lower memory consumption in many use-cases than Oracle's HotSpot JVM. My first small tests seem to confirm this. Has anyone else been running BaseX on either OpenJ9 or IBM J9? Thanks and keep up the good work. Kind regards, Vincent

Support for XML with different file extension in GUI
by Kevin Cline 15 Nov '18

15 Nov '18

Hello, In the GUI, is there any way to set the query context to an XML file that has an extension other than .xml ? Renaming the file works, obviously, but this isn't ideal, as the source of the data exports to and imports from another extension. Also, is it possible to enable syntax highlighting for XML files without changing the extension? I added the extension in Options->Preferences->File Filter, but nothing changed. Thank you for your help.

BaseX 9.1 behaviour of fn:trace
by Kittelmann, Maike 12 Nov '18

12 Nov '18

Dear fellow users, I updated to BaseX 9.1 and I observe an unexpected behaviour of fn:trace http://docs.basex.org/wiki/XQuery_3.1#fn:trace I inserted logging statements to give warnings in case important content is missing, like so: declare function local:my-function ( $id as xs:string?, $value as xs:string? ) as xs:string? { if ( $ value != '' ) then "foo" else trace( $id, 'No foo given for this record! ') } ; So far, the fn:trace output could be read in the Info window of BaseX. Now, the id-value of the above call to trace is ALSO output to the Result window. Even though the documentation states that the behaviour of trace is implementation-dependent, this behaviour seems unexpected and unhelpful. The extra output to result is hard to notice and destroys a possibly fully valid result file (the trace call is only a warning, there is not necessarily an actual error). 1. Is there anything wrong with my XQuery? 2. Why is trace behaving this way in BaseX 9.1? 3. How to best achieve the desired output? (Desired output is: result file unchanged and warning in Info window.) Thank you and best regards, MK

restxq
by Giuseppe G. A. Celano 11 Nov '18

11 Nov '18

I am trying to make a RESTXQ webservice I created with BaseX 8.3 available in Basex 9.2. I simply copied my "file.xqm" into the webapp folder but, when I type the path of a function contained in it, it does not work ("No function found that matches the request."). Strangely enough, when I minimally modify restxq.xqm, the modifications do not apply either. Any idea about what the problem might be? Thanks.
