how to pass serialization params to file:write
by Kevin S. Clarke 14 Sep '11

14 Sep '11

Hi, I'm having difficulty locating the proper syntax to pass to file:write(). The documentation says: $serializer-params as node()* but what does that element look like? <output method="text"/> or <serialization method="text"/> or <serialization method="xml" cdata-section-elements="div"/> or something else? I see I can set those as options in the XQuery itself too, but I'd like to figure out what I'm doing wrong. Thanks, Kevin

BaseX 6.8: Status Quo
by Christian Grün 12 Sep '11

12 Sep '11

Hi all, here at BaseX, we're more than busy to get our next release finished... which will contain a real bunch of new features: - the database store will also support binary (or "raw") files - the new WebDAV API can be used to store files similar to a file system - WebDAV will also provide a tight coupling to the oXygen editor - JAX-RX will be replaced with a native, better integrated REST API - the JSON module in XQuery converts JSON documents to XML and back - all XML documents can be serialized to JSON, using the JSON-ML standard - the SQL module facilitates the access to relational databases from XQuery - the new EXPath Crypto package supports cryptographic operations Some of the features are already documented in our Wiki (http://docs.basex.org/). Just search for "6.8" and you'll get more information. Next, many of the features are already found in our GitHub repository. As an example, BaseX is now disconnected from JAX-RX, and the starter class for both the REST and WebDAV services is now called BaseXHTTP. Keeping you updated; thanks all for your support, Christian ___________________________ BaseX Team Christian Grün Uni KN, Box 188 D-78457 Konstanz http://www.basex.org

Problem in inserting xml declaration while adding a doc into a collection
by Murthy Raju 12 Sep '11

12 Sep '11

Hi, I am newbie to Basex. I am trying to connect to BaseXJAXRX server from python and trying to add a document along with its xml declaration to a collection. The XML declaration is not getting stored. Here is the code snippet: ---- xml = '<?xml version="1.0" encoding="UTF-8" ?><Message><Product><Reference>2233</Reference><Product></Message>' session = BaseXClient.Session(settings.BASEX_SERVER_IP, settings.BASEX_SERVER_PORT, settings.BASEX_SERVER_USER,settings.BASEX_SERVER_USER) session.execute('SET DBPATH '+ settings.XMLDB_FOLDER) session.execute('OPEN ' + settings.XMLDB_NAME) session.add("2233.xml", "", etree.tostring(xml, encoding="utf-8", xml_declaration=True)) input = "declare option output:omit-xml-declaration 'no'; collection('" + settings.XMLDB_NAME + "')//Message[//Reference='2233']" query = session.query(input) query.init() while query.more(): product = query.next() print product session.close() ---- 'print product' results in the following: <Message><Product><Reference>2233</Reference><Product></Message> How do I ensure that the XML declaration is also stored? Is omit-xml-declaration the answer? How do I set it while running "add" on BasexClient.Session? Thanks Murthy Raju

BaseX steps for Calabash?
by Florent Georges 05 Sep '11

05 Sep '11

Hi, Has anyone ever thought about writing extension steps for Calabash, in order to evaluate queries using BaseX? Using either the standalone processor, or to send queries to the server. Regards, -- Florent Georges http://fgeorges.org/ http://h2oconsulting.be/

SET textindex / attrindex switched around
by Daniël Knippers 29 Aug '11

29 Aug '11

@version 6.7.1 Good evening, Small bug-report: I noticed something odd with the SET command when connected as a client: > set attrindex Full-Text Index: OFF > set textindex Attribute Index: OFF In other words; when I want to change the value of 'attrindex' the reponse mentions the Full-Text Index, whereas trying to change 'textindex' seems to actually change the Attribute Index. -- Daniël

XML name characters and regexes with multi-character escapes?
by C. M. Sperberg-McQueen 25 Aug '11

25 Aug '11

Recently I had occasion to test a string to see whether it is an NCName. I typed something like: matches("foo","\i\c*") But instead of the value 'true', I got an error message saying that '\i\c*' is an invalid regular expression. I believe it is a valid regular expression and that \i and \c are defined as multi-character escapes in XSD. Other multi-character escapes (., \s, ...) seem to be supported. Am I missing something? Since \i and \c vary for different versions of XML, perhaps BaseX is expecting me to tell it which version of XML I want to be using for them? I'm currently using 6.5.1 and have not checked against the current version of BaseX, but I don't see anything about regular expressions in the change logs. -- **************************************************************** * C.

XQuery / BaseX: distinct after sort
by Mainberger, Christof 24 Aug '11

24 Aug '11

Hi, I got some performance problems with basex: My query is distinct-values(for $item in doc('gemaelde')/items/item order by $item/kuenstler/@order return $item/kuenstler). It takes about 26 s for 1.500 items. Is there any possibility to formulate the query in other ways to make this faster? Or indexes/materialized views to support such kind of queries? This problem occurs only on our Debian (virtual) server, not on my PC. Are there any configuration parameters for basex-server (ram etc.), which might help? Thanks!

Embedded BaseX server restart
by Igor Farinic 23 Aug '11

23 Aug '11

Hi, we have problem with restart (stop and immediate start) of embedded BaseX server. The root cause is that when you close server socket it remains in a timeout state for a period of time and restart fails, because it is not possible to bind to a socket in timeout state. Enabling SO_REUSEADDR prior to binding the socket using bind allows the socket to be bound even though a previous connection is in a timeout state. Following fix in BaseXServer class should help (lines 94 and 95): socket = new ServerSocket(); socket.setReuseAddress(true); SocketAddress endpoint = new InetSocketAddress(port); socket.bind(endpoint); esocket = new ServerSocket(); esocket.setReuseAddress(true); endpoint = new InetSocketAddress(context.mprop.num(MainProp.EVENTPORT)); esocket.bind(endpoint); regards, Igor Farinic

vanishing namespace declaration
by Igor Farinic 16 Aug '11

16 Aug '11

Hi, in BaseX 6.7.2 beta we are hitting new issue, that we haven't observed in 6.7.1. I store following xml: <task oid="91919191-76e0-59e2-86d6-998877665544" xmlns="http://midpoint.evolveum.com/xml/ns/public/common/common-1.xsd" xmlns:c="http://midpoint.evolveum.com/xml/ns/public/common/common-1.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:my="http://myself.me/schemas/whatever"> <extension> <my:shipState>capsized</my:shipState> <my:dead xsi:type="xsd:integer">42</my:dead> </extension> </task> ... and when I retrieve it, the xsd namespace declaration is missing. However the xsd namespace is used in value of xsi:type attribute. regards, Igor Farinic

Re: [basex-talk] BaseXServer.bat not respecting the -c"SET DBPATH ..." option?
by Igor Farinic 15 Aug '11

15 Aug '11

Hi, I am hitting the same issue: When I pass set dbpath command on server start, it seems that the server sets the new value, but is partially ignoring it. Logs are created in new directory, however data are stored in default directory (~/BaseXData/). It is causing problems, because I cannot run 2 BaseXServer instances over the same directory. How to replicate: String serverPath = "SOME_PATH"; StringBuffer commands = new StringBuffer(); commands.append("-cset dbpath ").append(serverPath).append(";info"); new BaseXServer("-d", "-D", "-s", commands.toString()); Environment: BaseX 6.7.1 regards, Igor Farinic

Embedded BaseX server exits whole process
by Igor Farinic 15 Aug '11

15 Aug '11

Hi, in our junit tests we are starting BaseX server in embedded mode. The problem is that, if there is some problem (e.g. server socket is unable to bind to port), basex server will terminate whole process. When the process is terminated during automatic junit test execution, then maven surefire plugin will report that 0 test were executed and all passed ... and we will never know that there are some problems in our application code :( I am using following command to initialize BaseX server: server = new BaseXServer("-p" + port, "-d", "-D", "-s"); Environment: BaseX 6.7.1 regards, Igor Farinic

BaseX: Support for JSON
by Christian Grün 14 Aug '11

14 Aug '11

Dear all, we've just added a frequently requested feature to the latest snapshot of BaseX: JSON files can now be converted to XML and back to their original representation! The chosen XML representation is supposed to be well readable and easily editable. As there is no lossless, bidirectional conversion available for XML and JSON, we have also added support for the JsonML format, which allows to serialize arbitrary XML documents to JSON and back to XML. More information is found in our Wiki [1]. Feel free to check out our latest sources [2] and snapshots [3], and don't hesitate to give us your valuable feedback. All the best, Christian [1] http://docs.basex.org/wiki/JSON [2] https://github.com/BaseXdb/basex/ [3] http://files.basex.org/releases/latest/ ___________________________ BaseX Team Christian Grün Uni KN, Box 188 D-78457 Konstanz http://www.basex.org

Hello, I am new to BaseX and have a question regarding the Export XML feature. After doing a keyword search and filtering my results, I would like to export this filtered data into a new XML file. Selecting Export XML, it prompts me to save it to the same .xml file. However the results are not saved. Any help would be appreciated. Thanks. Marc

BaseX as a web application server -- output option media-type?
by Sebastian.Wiemer＠Bertelsmann.de 12 Aug '11

12 Aug '11

Hello, I tried to use basex 6.7.1 as a web application server through the jax-rx API: If you put the following file in the jax-rx directory of basex, then you have a simple web application: [c:\Programme\BaseX\jax-rx\index.html] declare option output:method "xhtml"; declare option output:media-type "text/html"; <html> <head><title>Testserver</title></head> <body> <p><a href="http://127.0.0.1:8984/basex/jax-rx/DBNAME?run=index.html">Testme!< /a></p> </body> </html> (DBNAME is you context for the xquery) Here comes the problem: the declare option output:media-type "text/html"; does not seem to work :-( But if you specify the serialization option directly in the URI: <html> <head><title>Testserver</title></head> <body> <p><a href="http://127.0.0.1:8984/basex/jax-rx/DBNAME?run=index.html&outpu t=media-type=text/html">Testme!</a></p> </body> </html> Then this works and is a very simple example of using BaseX as a web application server. Is it me or basex? Can anybody tell me, why the media-type=text/html output option did not work, when declared in the XQuery? Regards, Sebastian

maven plugin for basex server
by Kevin S. Clarke 09 Aug '11

09 Aug '11

Hi, I'm a fan of the Jetty Maven plugin and I was wondering whether anyone had written a BaseX Maven plugin that would allow you to start up the BaseX server from a Maven plugin. The Jetty one works like `mvn jetty:run` or `mvn jetty:run-exploded` ... I could see something like `mvn basex:run` working (where you would configure the BaseX server in the pom.xml). If noone has done this, I'll probably take a stab at it, but I thought I should check to see whether it had already been written before I put any work into it. Thanks! Kevin

(Un)comment lines in BaseX
by Christian Grün 06 Aug '11

06 Aug '11

Hi Derek, thanks for your donation! I'm glad to tell you that we've now added an "(Un)Comment" feature to the text editor of BaseX, and closed the corresponding GitHub issue [1]. Feel free to check out the latest snapshot [2]. As we have a rather minimalistic interface, we haven't added an extra button. Instead, you may use the shortcut "Ctrl + /" to comment and uncomment highlighted texts or lines in XQuery or XML files. One day in future we'll document all the available GUI shortcuts (or hope that someone's interested in extending our Wiki [3]). For now, you can have a look into our shortcut mappings in the source code: https://github.com/BaseXdb/basex/blob/master/src/main/java/org/basex/gui/la… All the best, Christian [1] https://github.com/BaseXdb/basex/issues/144 [2] http://files.basex.org/releases/latest/basex-6.7.2-SNAPSHOT.jar [3] http://docs.basex.org/wiki/Main_Page

xsd validation
by planetcomolli＠tin.it 06 Aug '11

06 Aug '11

Hi everyone! I have started using base-x recently and i have a question that it may be naive, but i can't find a solution. In the last version of the db you can use xslt transformation and i have been trying to do the same with xsd validation. I mean, validate xml documents through a xsd validator using Xquery... I have tried for a while but i was not able to find a solution to this problem, even using java utilities. Is there a possible way to validate xml through xsd in base-x? Sorry for my really bad english and congratulations for yours really well done db!! Best wishes, Alberto

Additional options of the .basex

02 Aug '11

Hi, I have the customized .basex that made from the BaseX 6.6.2. .basex example --------------------------------------------------------- # Property File. # You can set additional options at the end of the file. ... LANG = English ... # User defined section CREATEFILTER = *.xml --------------------------------------------------------- When I executed the XQJ in the BaseX 6.7.2-SNAPSHOT, I got the warning messages that "CREATEFILTER(LANG) not found.". (I changed the defined section of these options, but the phenomenon didn't change.) Can't I define the "CREATEFILTER" and "LANG" option on the .basex? Thanks, Oda
