REST service : How to run server side query with params?
by Anupam Bakshi 17 Jun '12

17 Jun '12

Hello, I understand that one way to run a rest based XQuery with parameters is to use the following ... http://localhost:8984/rest/DB/mult.xq?a=21&b=2 This is possible if the query is in the BaseX database. I need to use REST, but the query file (.xq) and .xqm, .xsl files need to be located on the server but not in the database. Can someone give me a pointer about how to do that? Thanks, Anupam

Bug by saving a big result file (4,2MO)
by Maud Ingarao 16 Jun '12

16 Jun '12

Hello I am generating quite big files from quite big xml datasources using xquery in BaseX (local). Everything works fine (5,8 minutes processing, but fine ;) But saving the file result is impossible : the GUI freezes and the file remains empty. When I generate the same file using XSLT in Saxon-B, it's a little bit longer but in the end, I get my 4,2MO result file. Have a nice day :) Maud -- Maud Ingarao IHPC (UMR 5037) Institut d’histoire de la pensée classique, de l’Humanisme aux Lumières Ecole Normale Supérieure de Lyon - Site Descartes - Bureau R322 15 Parvis René Descartes - BP7000 - 69342 Lyon CEDEX 07 +33 4 37 37 65 79 - maud.ingarao(a)ens-lyon.fr cerphi.ens-lyon.fr - pensee-classique.ens-lyon.fr institutdesanti.ens-lyon.fr - hyperdonat.ens-lyon.fr mutec-shs.fr - projet-plume.org - ahn.ens-lyon.fr http://www.cahier.paris-sorbonne.fr/ - je suis absente le vendredi - out of office on Fridays -

XML element case sensitivity
by David Leigh 16 Jun '12

16 Jun '12

I've been searching in the BaseX docs online and can't seem to find reference to what I'm seeing. It may be common knowledge in the XML community but I'm not highly skilled in XML. Here's my issue: I have XML files that I'm loading into my database where there is inconsistency in the case (capital vs. lower-case) of the tag names (XML elements I think?). For instance, I have a tag named "lyrics" and sometimes in the files (whose source is not necessarily under my control) that will be <lyrics> and sometimes <Lyrics>. It could of course, by someone's error also be <lYrIcS> or any other weird combination. Is there a way, either at database creation or via some option or at query time to say that "lyrics" = "Lyrics" = "LyRics", etc. i.e. to be case insensitive for the XML tag names? Thanks!

puzzle over namespace qualification and absolute vs. relative location paths
by C. M. Sperberg-McQueen 16 Jun '12

16 Jun '12

An unexpected phenomenon has arisen in the XQuery course I'm teaching today and tomorrow; I wonder if anyone on this list can shed any light on it. To reproduce: 1 build a database containing the document http://blackmesatech.com/2012/06/data/sonnet92.xml 2 evaluate the following expressions (a) . (displays the entire document) (b) ./* (ditto) (c) declare namespace n = "http://www.tei-c.org/ns/1.0"; ./n:TEI (again returns entire document) This one didn't surprise me; it's what I expected. (d) /TEI (ditto) This one surprised me, since the TEI element in the document is namespace-qualified, and I would not have expected the expression to match anything. At this point, I would be tempted to say "well, maybe when we built the database, BaseX set the default element namespace in the static context to the TEI namespace." That would explain the evaluation of this expression. But ... (e) ./TEI (returns nothing) If the default element namespace in the static context were the TEI namespace, I would expect this to work. If it were NOT the TEI namespace, I would expect (d) to fail. I'm having trouble explaining to the participants in my course (or to myself) why expressions (d) and (e) return different results. What am I missing? best regards, Michael Sperberg-McQueen

Webdav not working on Windows 7 and Basex 7.2.1
by Bob Horvath 13 Jun '12

13 Jun '12

I followed the instructions on setting up Webdav for Windows 7, but I am still experiencing problems. I know the server is up and running because the rest and restxq interfaces are working. But I can't get Windows 7 to use it as a webdav server. I get the usual "The folder you entered does not appear to be valid/ Please choose another". This site (http://shon.org/blog/2010/03/04/howto-fix-windows-7-64bit-webdav/ [1]) claims Windows 7 will not use basic auth, but points to the same MS page that shows how to change the registry. Is there a way to setup Webdav on basex so it uses digest authentication"? In case I missed something stupid, here is what my webdav parameters are in the registry… Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesWebClientParameters] "SupportLocking"=dword:00000001 "InternetServerTimeoutInSec"=dword:0000001e "ServiceDllUnloadOnStop"=dword:00000001 "ServerNotFoundCacheLifeTimeInSec"=dword:0000003c "ClientDebug"=dword:00000000 "FileSizeLimitInBytes"=dword:02faf080 "SendReceiveTimeoutInSec"=dword:0000003c "LocalServerTimeoutInSec"=dword:0000000f "FileAttributesLimitInBytes"=dword:000f4240 "AcceptOfficeAndTahoeServers"=dword:00000001 "ServiceDebug"=dword:00000000 "ServiceDll"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f, 00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00, 77,00,65,00,62,00,63,00,6c,00,6e,00,74,00,2e,00,64,00,6c,00,6c,00,00,00 "BasicAuthLevel"=dword:00000002 Bob Links: ------ [1] http://shon.org/blog/2010/03/04/howto-fix-windows-7-64bit-webdav/

Hanging when inserting attribute
by Alex Markin 13 Jun '12

13 Jun '12

Hello all. I've tried to execute query for $i in collection('stars')/csv/record return insert node (attribute {'id'} {generate-id()} ) into $i with this <http://www.onlinedisk.ru/file/889304/> file (1000000 strings with 3 integer in any in csv format). I had a hang of basex and onece got the following: Exception in thread "Thread-526" java.lang.OutOfMemoryError: Java heap space Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: GC overhead limit exceeded at java.awt.EventQueue.postEvent(EventQueue.java:261) at java.awt.EventQueue.postEventPrivate(EventQueue.java:215) Exception in thread "AWT-XAWT" java.lang.OutOfMemoryError: GC overhead limit exceeded Exception in thread "SIGTERM handler" java.lang.OutOfMemoryError: GC overhead limit exceeded and again - the folowing: Exception in thread "AWT-XAWT" java.lang.OutOfMemoryError: Java heap space at java.util.logging.LogRecord.<init>(LogRecord.java:151) at java.util.logging.Logger.log(Logger.java:607) at sun.awt.X11.XToolkit.processException(XToolkit.java:535) at sun.awt.X11.XToolkit.run(XToolkit.java:614) at sun.awt.X11.XToolkit.run(XToolkit.java:543) at java.lang.Thread.run(Thread.java:679) Hang was even when I changed generate-id() to "1". Seems like a bug. Markin Alex.

fn:trace() does not print
by Brock, David 08 Jun '12

08 Jun '12

Was using fn:trace() to print out warning statements during XQuery processing. Worked fine using SAXONICA XQuery, but does not print anything in BaseX. Is there a setting to get this to work, or is there some other call that I can make to do same? Thanks!
