BaseX 7.7 error in working with EQNames
by Dimitre Novatchev 11 Sep '13

11 Sep '13

Hi, Given this XML document (in file example.xml): Freude, schöner Götterfunken, Tochter aus Elysium, Wir betreten feuertrunken, Himmlische, dein Heiligtum. This XQuery expression (in file TesQNametExpression.xquery, in the same directory): let $doc := doc('example.xml') return string-length($doc/Q{ http://example.com/one}p[1]/@Q{http://www.w3.org/XML/1998/namespace}lang) produces: 0 However the correct result (which I get with Saxon 9.5.01) is: 1 Here is the "Query Info" from the BaseX UI: Compiling: - pre-evaluating fn:doc("example.xml") - binding static variable $doc - removing unknown element/attribute Q{http://example.com/one}p - pre-evaluating fn:string-length(()) - removing variable $doc - simplifying flwor expression Query: let $doc := doc('example.xml') return string-length($doc/Q{ http://example.com/one}p[1]/@Q{http://www.w3.org/XML/1998/namespace}lang) Optimized Query: 0 Hope that this information would be useful for identifying and fixing the issue. -- Cheers, Dimitre Novatchev --------------------------------------- Truly great madness cannot be achieved without significant intelligence. --------------------------------------- To invent, you need a good imagination and a pile of junk ------------------------------------- Never fight an inanimate object ------------------------------------- To avoid situations in which you might make mistakes may be the biggest mistake of all ------------------------------------ Quality means doing it right when no one is looking. ------------------------------------- You've achieved success in your field when you don't know whether what you're doing is work or play ------------------------------------- Facts do not cease to exist because they are ignored. ------------------------------------- Typing monkeys will write all Shakespeare's works in 200yrs.Will they write all patents, too? :) ------------------------------------- I finally figured out the only reason to be alive is to enjoy it.

XML results file saving
by rdepery＠mscgva.ch 10 Sep '13

10 Sep '13

Hello there, This is my first post to this list, and I’d like first thanks everyone involved in this project. I have a problem of xml saving right now, and it seems it is not related to baseX itself, but might be something else I need to find out. I have queries I run against one or two db, the result is quite big and appear “chopped”. For a long time, using the save button, saved the result (the complete or “chopped” file I was seeing in output window…(text). Since a few time, when I save, only a few nodes are saved or almost nothing… Sometime not even the result in showed in “text”. File is saved, but instead of saving 3 or 5 Mb it saves 55Ko sometime more, sometime less. Could someone tell me if it is rather a memory, java, variable, query or anything else problem? I reinstalled java (jre6, jre7….), went from basex 7.7 to 7.5, rebooted several times. Note: First time you do the query and save, it works fine (ie. on colleague’s computer), the next, it doesn’t.

Re: [basex-talk] WebDAV document retrieval

Hi Víctor (cc: basex-talk), …thanks for listing all clients you tried. One last question: using Windows XP Web Folders, is it possible to right-click files and choose "edit"?

Building a java library
by Joe Templeman 06 Sep '13

06 Sep '13

Hi, I'm new to basex and I'm trying to build an external java library which will return a list of documents for me to then query, but I'm running into a problem where it can't seem to find the class. This is the script I'm running: declare namespace t = "java:com.inkling.modules.Test"; let $loader := t:new("local") return ( t:fileNames($loader) ) In my root project directory I have a subdirectory for my java files so I start up the baseX gui using java -cp "BaseX76.jar:xmldblib/src/" org.basex.BaseXGUI and my java file (in xmldblib/src/com/inkling/modules/Test.java looks like: public class Test { String env; public Test(String environment) { env = environment; } public List<String> fileNames() { ...... } } When I try and run the xquery script, it just says Unknown Constructor Test.new(xs:string) Does anybody have an idea what I'm doing wrong? Any help is appreciated. Thanks, Joe

7.7 bug?
by Bill Beck 06 Sep '13

06 Sep '13

HI all, I'm getting this bug, which seems to happen when I have two clients talking to the db at the same time, one via the command line, and one through a socket connection using the PHP API. After this error, the data appears to be corrupt and the only solution is to quit the server and all clients, restart, and drop the database. Wasn't having this problem under the same usage with 7.0.2. THanks, -BB Here's the error message: BaseX 7.7 [Client] Try help to get more information. > list name Resources Size Input Path ------------------------------------------------------------------------- collection_guides 2 242308 /var/www/html/collection-guides/xml 1 Databases. > list collection_guides Improper use?

WebDAV document retrieval
by Víctor Villamayor Callejo 05 Sep '13

05 Sep '13

Dear all, I would like to access my BaseX database through WebDAV, in order to be able to open, edit and save xml documents with custom made software that only works with files in the filesystem. I tried with WinXP Web Folders, NetDrive and WebDrive clients. I also tried with BaseX 7.7 and 7.6. My problem is that whenever I save a XML document, after a few seconds it is added (or replaced) to the database, and then it shows 0 bytes on the WebDAV client. Then I can access the document with the BaseX GUI for example, but I cannot double-click it in the client because it opens as an empty file. The exceptions are raw or incorrect xml documents, which are correctly retrieved. So WebDAV allows me to add, replace, rename, and delete xml documents, but not retrieve them. Is this the expected behaviour, a bug, or a locking matter?

external parameters with basexgui?
by Graydon Saunders 05 Sep '13

05 Sep '13

Hi! I've been failing to find this for awhile now. I've got some queries which I need to run from both a command line, using Saxon, for production purposes, and from the BaseX GUI, for development and testing and "that looks weird..." purposes. Saxon requires that I pass in content as parameters. That's easy enough. Is there a way to do this -- pass an external parameter value to a query -- with the BaseX GUI? Thanks! Graydon

Xquery on 2 DBs taking more execution time !!
by John Best 05 Sep '13

05 Sep '13

As the data is quite huge around 2GB, which creates problems while creating FT Index, I have divided it into 2 parts. For a better picture of what I have done, I am explaining it with a suitable example. Lets say I have articles on Physics in one single DB. So, I divided them into 2 DBs, viz; short description and long description. So, now I have 2 DBs - PhysicsSD PhysicsLD By doing so, I am not getting OOM now while creating FT Index. (Wow!!). But now, I am facing another issue... Say, I want to search for words "emf" and "waves" into the Physics DBs, I would do this - for $dbname in ('physicsSD', 'physicsLD') for $x in doc($dbname)//Doc[SD/Info/ text() contains text {"emf waves"} all words or LD/Info/Para/text() contains text {"emf waves"} all words] order by xs:integer($x/Details/Year) descending return $x/Doc This query retrieves data in approx. 83000 ms (83 Sec) But when executed on INDIVIDUAL DBs, the total time is very very less compared to the above. Its only 4500 ms (4.5 sec) for BOTH !!! -- Have a nice day JBest
