Problems with option XINCLUDE
by Hans-Juergen Rennau 04 Jan '16

04 Jan '16

Dear BaseX team, I face unexpected problem when trying to switch off xinclude processing. From the documentation I understand that what I have to do is set the option XINCLUDE to the value "false". But how? Attempt #1========= I added to the config file .basex the line: XINCLUDE = false Result: no effect, and these messages: C:/Program Files (x86)/BaseX/.basex: Unknown option 'XINCLUDE'. C:/Program Files (x86)/BaseX/.basex: writing new configuration file. Did I misunderstand the documentation? Attempt #2======== I inserted into the query this initial line:declare option db:XINCLUDE 'false'; Result: Program crash with this message:[FODC0002] "file:///C:/projects/otds/otds-config/h.xml" (Line 1): Vorzeitiges Dateiende. where the named file (h.xml) is the output (!) file specified either like this:basex foo.xq > h.xmlor like this:basex -o h.xml foo.xq Note. Using neither > ... nor -o ..., I do get the correct output, written to stdout. But I must capture it, and the capturing fails! Attempt #3======== Patching the basex.bat file, inserting option -D: java -Dorg.basex.XINCLUDE=false -cp "%CP%" %BASEX_JVM% org.basex.BaseX %* Result:Same as attempt #2 So I'm at a loss. I need to switch off xinclude because my input files use xinclude in combination with xpointer attributes, like this: <xi:include href="../../../globals/notifications.xml" xpointer="xpointer(/config/*)" parse="xml" /> Applying doc(...) to such a file, yields this result: [FODC0002] "file:///C:/projects/otds/otds-config/branches/path/to/bar.xml" (Line 11): "include" mit href "../../../globals/notifications.xml" nicht erfolgreich, und es wurde kein "fallback"-Element gefunden. Can you help me? Hans-Jürgen PS: Using version:BaseX 8.3 beta 474994c [Standalone]

AWS Deployment, .war-file writing
by kleist 04 Jan '16

04 Jan '16

Hi all, I want to deploy my baxex-App to Amazon Web Services (AWS). Therefore I need a .war file of my existing application, not only the war-file of basex. How can I do it? There is the excellent tutorial of Paul Swennenhuis about Deployment on AWS (Part II). But it's a little bit outdated. AWS is now using tomcat 8 and it is no more stored at /var/lib/tomcat... Does anybody know, where I can find the new root-directory? Thanks for any help, Günter

Ignore option for full-text-search
by kleist 04 Jan '16

04 Jan '16

Hi Christian, my long-time project (kleist-digital.de) is nearly only based on documents (TEI-xml), so I'm working mostly with mixed content. Are there any plans for future versions to implement the ignore option for full-text-search? It would help a lot. Best, Günter

can't make Geo Module work
by Eric Boisvert 03 Jan '16

03 Jan '16

Greetings I just downloaded BaseX 8.3.1 .war and installed it on Tomcat 7 (jre1.8.0_66) running Windows 7. enterprise (SP1). Did nothing (just loaded a single XML file) throught the web based admin interface and tried this XQuery import module namespace geo = "http://expath.org/ns/geo"; declare namespace gml='http://www.opengis.net/gml'; let $point := <gml:Point><gml:coordinates>1,2</gml:coordinates></gml:Point> return geo:geometry-type($point) (it's from Geo Module documentation at http://docs.basex.org/wiki/Geo_Module#geo:geometry-type) all I get is *[XPST0017] Unknown function 'geo:geometry-type'.* in the logs, I have [POST] http://localhost:8080/BaseX831/dba/eval-query?name=&resource=&sort=&loglist=; Stopped at C:/Program Files/Apache Software Foundation/Tomcat 7.0/webapps/BaseX831/dba/modules/util.xqm, 94/17: [XPST0017] Unknown function 'geo:geometry-type'. The java Geo.class are present (webapps\BaseX831\WEB-INF\classes\org\expath\ns) Other trivial XQuery do work Any idea what's wrong ? Thanks and Happy New Year

GUI feature request "Add as import"
by Andy Bunce 03 Jan '16

03 Jan '16

Hi, I often find myself adding module imports in the GUI and I wonder if the following suggestion might speed up that process. Add a new menu item to the filelist right click context menu "Add as import" when the file selection is a XQuery module. The action would be to add a line to the current edit window source with import module namespace {$prefix} = '{$namespace}' at {$path}; Where $prefix and $namespace} are read from the source of the selected file, and $path is calculated from the relative path from the edit file source to the selected filelist source. The line would be inserted at a suitable place in the prologue or at the current location if that is too tricky. /Andy

archive:extract:-binary can cause OutOfMemoryException
by E. Wray Johnson 02 Jan '16

02 Jan '16

I have written an XQuery that properly extracts binary(raw) archive resource contents to binary(raw) resources. However since archive:extract:-binary returns the contents as xs:base64Binary and not streamable items, large archive contents are loaded completely into memory and will often cause an OutOfMemoryException. I have increased the BaseX JVM heap size and the problem goes away, but this is not acceptable in a system where many users may be doing this concurrently. archive:extract-to seems to only extract to an external file-system location and not to binary(raw) resources. Example code is provided below that extracts to the same database folder as the archive, however the target location of the contents is not pertinent to the problem. let $database := 'db' let $archivePath := 'myfolder/myarchive.zip' let $archive := db:retrieve($database, $archivePath) let $basePath := replace($archivePath, '[^/]+$', '') let $entries := archive:entries($archive) let $contents := archive:extract-binary($archive) for $entry at $pos in $entries let $content := $contents[$pos] let $target := $basePath || '/' || $entry/text() return db:store($database, $target, $content)

Java module to add documents to database
by Kevin S. Clarke 01 Jan '16

01 Jan '16

Hi, I'm writing a Java module that will do a couple of things, in addition to adding documents to a BaseX database. I've gotten the other things done, but I'm stuck a bit about how to add docs to the database from a module (I've seen the example that returns xml fragments that can be used from the xquery side). I see on http://docs.basex.org/wiki/Java_Examples that there are local/embedded and client-api ways to interact, but a module would want to be able to work in either situation. Are there any module examples that write to the database that someone would like to share (or just point me in the right direction)? Thanks, Kevin

Versioning
by Laurent Pellegrino 31 Dec '15

31 Dec '15

Hello all, I discovered BaseX recently and I find it really powerfull. Unfortunately, I read that versioning was not supported out of the box in 2014 [1]. Is it still the case ? Is there no simple workaround ? My usecase is the following. I have thousands of XML files which are indexed using BaseX in a specific database, lets say "mydb". At some point of time, a user may want to add a new XML file which is a slightly modified version of one already indexed by BaseX. I would like to be able to: - store this new XML resource in "mydb" database without loosing the XML from which it is issued - to retrieve the latest version or a previous one. - filter resources based on the latest version A simple way to achieve such a behaviour would be to be able to index a XML resource in BaseX with some additional meta information such as an ID and a timestamp, and then offer the possibility to use these meta information in an XQuery to filter resources. Is it possible with BaseX 8.3 ? I am looking for a solution that does not a require another database.

Full-text search with ft:mark (linking back)
by kleist 31 Dec '15

31 Dec '15

Dear members, given for example: ft:mark(//p[.//text() contains text 'real']). This will yield some results. Is there any way, to link back to the documents, where p was found? I know, it would work without ft:mark, but I need the <mark>-tag inside of the results, especially for fuzzy-search-results. Any help would be appreciated. - Günter

Store command with InputStream
by buddyonweb-software＠yahoo.com 29 Dec '15

29 Dec '15

I am writing a Java program that creates some text data that I want to store as a 'raw' document in a database.In the JavaDocs for the Store command () it states for the constructor public Store(java.lang.String path): "Constructor, specifying a target path. The input needs to be set via Command.setInput(InputStream)." Since the input is not a file, but rather an InputStream of data in memory, I do indeed call setInput. However, I cannotget this to work. Am I doing something wrong? Must the input only be from a file (and not from data in memory)? Here is snippet of code and thanks in advance. Note: Using the client/server mode. ClientSession session = new ClientSession(host, port, user, pwd); session.open("MyDb"); String theData = someFunctionThatReturnsALargeStringOfData(); ByteArrayInputStream bais = new ByteArrayInputStream(theData.getBytes()); Store cmd = new Store("newFile.txt"); cmd.setInput(bais); session.execute(cmd); session.close(); Note sure if this helps, but this is the stack trace I get. org.basex.core.BaseXException: Stopped at , 1/63: Syntax: STORE (TO [path]) [input] Store raw data. Stores raw data to the specified [path]. at org.basex.api.client.ClientSession.receive(ClientSession.java:193) at org.basex.api.client.ClientSession.execute(ClientSession.java:162) at org.basex.api.client.ClientSession.execute(ClientSession.java:167) at org.basex.api.client.Session.execute(Session.java:36) ......
