restxq: default namespace and variable in path annotation don't like each other
by Jean-philippe Magué 17 Dec '13

17 Dec '13

Hello, We think we've found something that looks like a bug. In the minimal file test_A.xqm, we declare a default namespace and a function with a very simple path annotation (without variable). It works just fine. In test_B.xqm, we just declare a function with a variable in its path annotation. This is OK as well. In test_C.xqm, we declare both a default namespace and a path annotation with a variable. This raises a NullPointerException as you can see in error.html (which also provide version number informations). The choice between variables in path annotation and default element namespace is a difficult one! We'd like to use them both! Or are we missing something ?

Serializing unescaped xml to string
by Joe Templeman 16 Dec '13

16 Dec '13

Hi all, Is there a way to output unescaped XML to a string for debugging purposes? In unittests we would like to output the XML returned when a test fails, here is my example: declare %unit:test function elementinfo-test:test-element-info() { let $cases := <cases> <case> <comment>Failed input</comment> <input>input</input> <output> <result> output </result> </output> </case> </cases> for $case in $cases/case let $result := {some function which returns XML} let $u := unit:assert(deep-equal($case/output, result), $case/comment/text() || " Input: " || $case/input/text() || " Expected: " || fn:serialize($case/output) || " Got: " || fn:serialize($result)) return $u }; But when a test fails, I get escaped XML as the output. Is there any way to get this as actual XML? Thanks, Joe

Getting started
by Ihe Onwuka 14 Dec '13

Finally took a look - very impressive. I got some warnings on the command line, one about tagsoup which I have fixed, another that bamboozled me because I have a java runtime installed......any here is what I get..... I've looked for a search for the mailing list but it seems to be well concealed - so what should I do. [warning] /usr/bin/basex: No java runtime was found [warning] /usr/bin/basex: Unable to locate /usr/share/java/tagsoup.jar in /usr/share/java [warning] /usr/bin/basex: No JAVA_CMD set for run_java, falling back to JAVA_CMD = java

strange behaviour of the BaseXgui-editor
by Rob Stapper 14 Dec '13

14 Dec '13

Hi, I encountered a few (3) problems with the BasexGui-editor. I use the 7.8 beta release but the issue's also occur in previous versions. Problem 1: this is a minor problem but maybe related to problem 2 which is ( for me) a major problem: If I open two ( small) packages of which one has no errors and one has errors then the errorstatus-message at the bottom of the editor doesn't synchronize correctly when switching files. If I switch from the incorrect packagefile to the correct packagefile the errormessage doesn't refresh to 'ok' until I edit this file. Even after closing an activated incorrect packagefile the errormessage stays active. Clicking on the message even reopens the incorrect packagefile. Switching the focus from the correct packagefile to the incorrect packagefile however, doesn't show this behavior. In that case the errorstatus-message changes to the appropriate errormessage of the incorrect file. Problem 2: which is a major problem when working with big files ( 80 kB) I found that when editing a large(r) packagefile the Basexgui-editor doesn't recognize errors that occur after a certain point in the file. If errors occur after this point the errorstatus-message shows 'ok' but I know that the file contains errors and if I try to install the file as a package I get an window with the message below. If the error occurs before that certain point then I get an correct errormessage. However if I delete the code which contains the error the error-message remains. Clicking on the message brings the cursor to the point where the deleted code with the error used to be, even after saving and closing the file. Errormessage ============================================================================ ============================================== Improper use? Potential bug?

I found a new clue which might help you solving this issue. The issue was when working in fullscreen mode (F11) in the BasexGUI and then saving a file with 'save as .' The save-messagebox gets the focus but disappears behind fullscreen basexgui-window. This has something to do with using a dual monitorsystem. On a single monitor system it works ok: The save-box is placed on top of the fullscreen Basexgui-window and gets the focus. On a dualmonitorsystem the save-box is placed behind the fullscreen Basexgui-window and gets the focus. I hope this insight helps you tackle this minor issue. Well, that's all folk. I hope you can solve the editor-problem soon because I have a really hard time debugging my (large(r)) programs. Regards, Rob Stapper

Xquery for multiple files
by Mansour Al Akeel 13 Dec '13

13 Dec '13

Hello all, I am not sure if this can be done in XQuery, and if BaseX makes it possible, but I am trying to query all the files under a directory. This directory is copied through webdav. For example, I need to get all the files that have root <article>. Searching for how to do this, I came across this post, that shows how to do something similar with marklogic http://stackoverflow.com/questions/19243253/search-and-load-all-xml-files-i… How to do this in BaseX if possible ?? Thank you.

fn:doc("c:/...")
by Hans-Juergen Rennau 13 Dec '13

13 Dec '13

Dear BaseX team, I'm a little confused by the behavior of the fn:doc function: doc('/c:/projects/foo.xml') yields this error msg: [FODC0002] Line 1: No text allowed before root element. Whereas these work: doc('c:/projects/foo.xml') doc('file://c:/projects/foo.xml') Is this a bug or a feature? At any rate the error msg is confusing. I've used the latest snapshot (20131211.173706). Kind regards, Hans-Juergen
