Re: [basex-talk] XPath child::node() axis sequence order
by Christian Grün 12 Dec '13

12 Dec '13

Hi Wendell (cc @basex-talk), thanks for your mail. Yes, there are cases in which the result of an axis step are not returned in document order. One such example is shown as follows: Document Order: <A> <B><c/></B> <c/> </A>//c / parent::node() No document order (when using the map operator): <A> <B><c/></B> <c/> </A>//c ! parent::node() I was using parent::node() instead of child::node() here, but the example can surely be adapted to also include a child step. Hope this helps?

Any way to access attributes directly from XQItem class?
by Ando Roy 11 Dec '13

11 Dec '13

Hi all, I have a question regarding the XQItem class from the XQJ apis. Let's say that I have a XQResultSequence obtained from executing a query, with the result sequence containing a number of XQItem objects. If I were to print each of them as strings they would look like: <CUSTOMER UserID="abc" Password="123"/> How can I access the attributes in this XQItem directly? Must I write a parser for this, or is there an easier way? Regards, Roy

XQuery development and Access through URL
by Mansour Al Akeel 11 Dec '13

11 Dec '13

Hello all, I am new to BaseX. I am using the war file, deployed to tomcat and looking for a way to create an xquery file and execute this query through a URL. For example, under WEB-INF/repo/hello.xq and call it with http://localhost:8080/BaseX/hello Any modification for the xquery file, will be reflected in the next URL request. Does BaseX support something like this ?? Thank you.

Alternative to XQDT ?
by jean-marc Mercier 11 Dec '13

11 Dec '13

Hello, I am developing using Eclipse, together with the integrated xquery editor provided by XQDT. This last editor does not seem to support xquery 3.0 syntax. I can survive, but there are a lot of nice functionality that are not working anymore (for instance the outline windows). Does someone know any alternative to XQDT editor that could integrate with eclipse and is xquery 3.0 compliant ? Cheers Jean-Marc

Basex Gui as server client?
by José Tomás Atria 11 Dec '13

11 Dec '13

Hello all, I am trying to run basex as a system daemon in ubuntu linux, and I have managed to get the server up and running on its own home dir, etc[1]. I can connect to the server with both the supplied basexclient CLI utility, and with my own perl client (using a local implementation of the server API), however, I am incapable of instructing the GUI client to use the system server... I can connect to the system server using the "Server administration dialog", that works and shows users, sessions and databases for the running system server, but when I tried opening a database, it complains that it can't faind any... I assume because it is looking for them in my user home dir. I can see the server dbs if i enter the server data path (ie, /var/lib/baxsex ) as "database path" in the GUI preferences, but i obviously get a "permission denied" error when trying to open them as local dbs. Can the GUI client be used to connect to a running (maybe even remote) server instance? How? Any help would be extremely appreciated. Thanks! jta. [1] I'm using java-service-wrapper ( http://packages.ubuntu.com/saucy/service-wrapper) with this conf and startup script: https://github.com/jtatria/basexd -- entia non sunt multiplicanda praeter necessitatem

SET GLOBAL OPTION DBPATH
by Ramesh 10 Dec '13

10 Dec '13

Dear Christian, Basex Previous versions like 6.7 supported to set GLOBAL OPTION "DBPATH" by user choice, So when we are creating collections we are setting one DBPATH for one collection as per our functionality by using below sample code.. for collection1: -------------- Context context = new Context(); new Set("dbpath","dbpath1).execute(context);// Here we are setting DBPATH new CreateDB("collection1").execute(context); for collection2: -------------- Context context = new Context(); new Set("dbpath","dbpath2).execute(context);// Here we are setting another DBPATH new CreateDB("collection2").execute(context); But when changing Basex6.7 to Basex7.2 version, we are unable to set GLOBAL OPTION "DBPATH" . As per our R&D the DBPATH getting form one of the system property "org.basex.path", once we are set system property unable to change it as for our functionality we have to set different DBPATHS like above code.... when we are trying to set DBPATH like above code we are getting below Exception org.basex.core.BaseXException: Global option 'DBPATH' cannot be set. Please provide any suggestions for us.. Thanks& Regards Ramesh -- This message is for the intended recipient only.

server side restxq calls
by Eckey, Florian 10 Dec '13

10 Dec '13

Hi, during implementing my website based on BaseX with restxq, I run into a problem. In BaseX it is only possible to execute either updating or non-updating xquery expressions in a function. So if I want to mix updating with non-updating expressions I have to execute a restxq call (updating) which forwards to another restxq call (non-updating). I know the possibility of using db:output("some non-updating expression"), but I guess it is not the right way if I only use updating-functions with db:output(...). Like: declare updating function ns:foo(...) { db:output("some code") } So my idea is to execute server side restxq calls, like: restxq:call("user/1"), which delivers the output of the function behind. I tried out going the external way with http:send-request(<http:request method='get' href="https://localhost:8443/user/1"/>). But I get problems with the SSL connection. If I open another non-SSL basex server a different port it is not possible to execute restxq calls as well, because of the jetty security module I use. So are there any clever ideas either to mix updating with non-updating functions (and not abuse transaction security) or do server side restxq calls? Best regards, Florian
