Details on the new and modified functions are listed at: http://basex.org/xquery We'll add numerous other function libraries in near future. If you have any requests..

update on context nodes
by Stefano Santoro 12 Nov '10

12 Nov '10

Hi, when I bind a DOM tree as the context item in XQJ against an XQuery script that performs updates, the passed DOM tree is not modified. Here is a groovy example import groovy.xml.XmlUtil import groovy.xml.DOMBuilder import groovy.xml.dom.DOMCategory import javax.xml.xquery.XQConstants docbuilder = DOMBuilder.newInstance() doc = docbuilder.sample() { renameMe(id:11) { renameInner(isit:"true","yes") } deleteMe(id:12) { alongWithMe("bummer") } insertBeforeMe(id:14) { alongWith(me:"true","Oh Yeah") andMe(too:"yes","Oh Yeah") } insertAfterMe(id:15) { atLevelThree(level:3) { atLevelFour(level:4, "fourth level") atLevelFour(level:4, "fourth level again") } alongWith(me:"true","Oh Yeah") } } // prints the DOM tree before updates XmlUtil.serialize(doc, System.out) ds = Class.forName("org.basex.api.xqj.BXQDataSource").newInstance() cnn = ds.getConnection() stmt = """ let \$r := . return ( rename node \$r/renameMe as 'gotRenamed', delete node \$r/deleteMe[@id='12'], insert node <gotInsertedBefore id='13'> <alongWithMe>Cool</alongWithMe> </gotInsertedBefore> before \$r/insertBeforeMe[@id='14'], insert node <gotInsertedAfter id='16'> <alongWithMe>Cool</alongWithMe> </gotInsertedAfter> after \$r/insertAfterMe[@id='15'] ) """ xe = cnn.prepareExpression(stmt) xe.bindNode(XQConstants.CONTEXT_ITEM, doc, null) xqs = xe.executeQuery() // the DOM tree was not modified XmlUtil.serialize(doc, System.out) xqs.close() xe.close() cnn.close() Should I pass it as an external variable instead?

Re: [basex-talk] Can't build using maven 3
by Michael Seiferle 10 Nov '10

10 Nov '10

Hi Stefano, (this time with cc to the list, as this might be of general interest :-)) sorry again for the inconvenience. We currently have no automatic deployment of the minor Version jars to our repository (we are about to change that soon, hopefully). The recoomended and "clean" solution is installing the latest repository version of BaseX into your local subversion repository via: > $ cd basex > $ svn up > $ mvn -DskipTests=true install This should avoid the errors below. Let me know if this helps and feel free to ask more! Kind regards Michael Am 10.11.2010 um 19:41 schrieb Stefano Santoro: > [WARNING] The POM for org.basex:basex:jar:6.3.2 is missing, no dependency information available > Downloading: http://repository.codehaus.org/org/basex/basex/6.3.2/basex-6.3.2.jar > Downloading: http://www.inf.uni-konstanz.de/dbis/basex/maven/org/basex/basex/6.3.2/basex… > Downloading: http://repo1.maven.org/maven2/org/basex/basex/6.3.2/basex-6.3.2.jar >

predicate evaluation issue
by Martin Gieseking 10 Nov '10

10 Nov '10

Hello again, :) I think, I've found another bug. This time it's somehow related to implicit type casting. When running the query /a/b[@*=2] on the following XML document, both b nodes are selected, although the first one has no matching attribute. /a/b[@*='2'] returns the correct node. <a> </a> Best regards, Martin

types & encoding when talking to BaseX server
by Godmar Back 10 Nov '10

10 Nov '10

Hi, I have 2 questions regarding: https://svn.uni-konstanz.de/dbis/basex/trunk/api/etc/java/BaseXClient.java a) create() takes an InputStream. Which character encoding is assumed (I'm guessing UTF-8?) b) Query.next() returns a String. Is there a way/need to determine the type of the Query result (e.g., String, boolean, etc.)? (Or is an XQuery's result type statically determinable, in which case this would not be needed?) - Godmar

Re: [basex-talk] BaseXGUI
by Christian Grün 10 Nov '10

10 Nov '10

Dear Luca, > Hi, I'm playing with basex and succesfully running a server and the basic client BaseXClient remotely via an internet connection. I'm trying to do the same thing with BaseXGUI but I can only administer the remote server via BaseXGUI. Is there a way to connect and issue commands to a remote server using BaseXGUI? Currently, that's not possible; the visualization demand a much tighter integration with the backend, which cannot be realized via the client/server architecture. As this a frequently requested feature, we might add a console mode in a future version to allow text-based requests via the GUI. Best, Christian PS: mails to the mailing list are preferred.

erroneous evaluation of position() on descendant axis
by Martin Gieseking 09 Nov '10

09 Nov '10

Hi, while playing around with BaseX, I stumbled over some weird results in conjunction with positional predicates on the descendant axis. As far as I can see, there seems to be a bug in the evaluation of function position(). Example: When I load the following XML document and evaluate the path expression /descendant::c[1], both c element nodes are returned, but only the first one is expected. So, currently the result is identical to that of //c[1]. <a> <c/> <c/> </a> Best regards, Martin
