Error?
by Lars Johnsen 12 Mar '15

12 Mar '15

Hi all I have a database collection which gives a strange error message '[FODC0002] "" (Line 1): Content is not allowed in prolog.' on this query: for $x in collection('samtiden') return doc(document-uri($x)) The results from document-uri($x) are as expected, but doc(document-uri($x)) should return $x - so what can be the cause of the error? The collection was entered in the gui using "skip corrupt files" since some of the files had errors (ended prematurely). But the database and document-uri() works fine for all elements in the database. I need to process the paths for grouping the documents in the collection, so the practical value is a bit more than just trying to compute a unity function!

Database Path preference doesn't persist across sessions (v8.0.1/v8.0.2)
by Amanda Galtman 11 Mar '15

11 Mar '15

Hi, I just started using version 8.0.1 and 8.0.2 after having used version 7.9 for awhile. In some GUI sessions, when I enter a Database Path preference value in the Preferences dialog, the value gets used during that session but does not persist in the next session. The .basex file in my .basexhome directory is not being updated to reflect the value I entered in the dialog. The strange thing is that this might not be the case for every session. My .basex file for version 8.0.1 had a custom value in it, which I know I did not set manually in the .basex file. However, today I cannot get it to reflect any other values that I enter in the GUI. As a workaround, I can manually enter a path on the DBPATH line in my .basex file. But I wanted to report this issue anyway. I am using Windows 7, and the .basex and .basexhome files are in my BaseX installation directory. I would be suspicious about Windows administrator permissions, except that this works fine in BaseX 7.9, where .basex is in an analogous location on my hard drive. Thanks, Amanda

Hi, Doh! Mea culpa: I made an error in the name of the parameter (not the one in the example above), so of course the binding never worked. All of the syntax works (in GNU/linux's bash ), except -b"$db-name=Value" because the shell will interpret $dp, so one must use instead: -b'$db-name=Value' 2015-03-05 10:54 GMT+01:00 Olivier Jeulin <olivier.jeulin.work(a)gmail.com>: > Hello, > > I'm also strugling to pass parameters: > in my XQuery : > declare variable $db-name external; > I tried, following the documentation “-b$v=example” : > basexclient script.xq -b\$db-name=Value > basexclient script.xq -b"$db-name=FichiersBase" > basexclient script.xq -bdb-name=Value > basexclient script.xq -b"db-name=Value" > > and everytime: > [XPDY0002] No value assigned to $db-name. > > What's the correct syntax???! > > > 2015-02-23 16:44 GMT+01:00 Marco Lettere <marco.lettere(a)dedalus.eu>: > >> Hello all, >> I'm unable to execute the example from documentation: >> >> bin/basex -b$v=example "declare variable $v external; $v" >> >> IT gives this exception: >> >> Stopped at ., 1/19: >> [XPST0003] Expecting '$', found 'e'. >> >> Any clues? >> Regards, >> MArco. >> > >

Concurrent handling of reads while ADDing a file
by David Mathei 10 Mar '15

10 Mar '15

Hello BaseX Team, I am loading a big file into BaseX (2.1G) and try to understand the handling of concurrent reads during that process. The size does only matter in so far, as loading seems to block reading for an extended amount of time. I observe that I can not read the collection I'm loading into nor any other collection under the same server. When I use another server process on a different port to write to the target collection I can read other collections without delay, the collection I'm loading into is (obviously) blocked by the upd.basex flag. Is there no parallelisation involved that would separate reading from writing processes, or does that only come into play for xquery updates that run under the transaction module? My PARALLEL setting is at the default of 8 and I'm on version 8.0.1. And I apologise already if I missed some obvious configuration... Thanks to everyone involved in this project! David Mathei

XSLT transformations in BaseX with XSLTforms fails
by Kristian Kankainen 05 Mar '15

05 Mar '15

Hello! I try to transform XForms with XSLTforms with the xslt module in BaseX but fail. I use the examples given by XSLTForms which work in the browser. My xslt:processor() gives 'Java' and xslt:version() gives '1.0'. The error message I get is: *type* Status report *message* _Stopped at /usr/share/tomcat/webapps/BaseX80-20150207.113013/hans.xq, 242/23: [bxerr:BXSL0001] ERROR: 'Could not compile stylesheet' FATAL ERROR: 'Error checking type of the expression 'FilterParentPath(variable-ref(profiler0/result-tree), step("child", 1))'.' :Error checking type of the expression 'FilterParentPath(variable-ref(profiler0/result-tree), step("child", 1))'. Stack Trace: - /usr/share/tomcat/webapps/BaseX80-20150207.113013/hans.xq, 165/10_ *description* _The request sent by the client was syntactically incorrect._ My XQuery looks like this: declare %rest:path("hans/xforms") %rest:GET %output:method("text") function hans:xforms() { let $page := <html xmlns="http://www.w3.org/1999/xhtml" xmlns:xf="http://www.w3.org/2002/xforms" > <head> <title>Many to one</title> <xf:model> ... snip ... </html> return xslt:transform($page, 'static/xsltforms/xsltforms/xsltforms.xsl') }; The only difference between the input given in the function and the one given at http://www.agencexml.com/xsltforms/incremental.xml is the removal of two processing instruments: <?xml-stylesheet href="xsltforms/xsltforms.xsl" type="text/xsl"?> <?xsltforms-options debug="yes"?> What could be the source of this error? How should I continue debugging this? Best wishes Kristian Kankainen

Binding Object Through Java
by ankit kumar 04 Mar '15

04 Mar '15

Hi, I am using BaseX 8.0.1 version. I am using basex in in-memory embedded mode. I am running a program in Java. My Query execution is taking almost two second, out of which binding Iter to the QueryExecuter is taking almost a second. If i can reduce the binding time, It would boost performance significantly. What step should i take to reduce the same. let me know, What other details you would like to have from me. Thanks

Comparing NxDs
by Mansi 03 Mar '15

03 Mar '15

Hello, I am a happy BaseX user. Currently I am trying to help other teams to find right solution to their data mining from huge xml data store. They are going after postgre and probably even db2. Nor that I have any influence over their decision, but I would like to alert them about something obvious. I just wanted to have some comments from experts here, to give me guidance on what is a major different between these relational DBs supporting native xml storages as compared to BaseX or whatever. I know postgre doesn't support xquery, but db2 does. As you all are aware, our queries won't be complicated probably even xpath might work, just amount of data would be huge. We won't even care hugely about the time taken to return results as long as it's not days. Please advice, - Mansi

Small detail
by France Baril 03 Mar '15

03 Mar '15

Hi, Is it possible to add the name of the DB to this message: [XUDY0016] Document can only be replaced once: menu/app-help-wirelessdisplay.xml. We have 1 DB for each of our 32 languages and we batch process. Since all updates are done by baseX at then end, we can't just get the language from a trace in the loop that goes through languages. Thank you! -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com
