Dear all, we've just returned from the XMLPrague conference, and it has been a great experience to talk to some of you live! Michael has written a blog entry, which summarizes some of the impressions: http://micheee.github.com/blog/2012/02/13/basex-xml-prague/ For those of you who were wondering about our slow feedback.. Be prepared to get your feedback soon, Christian PS: Similar to last year, there will be a minor 7.1.1 stability update, resulting from the feedback we've got so far. ___________________________ BaseX Team Christian Grün Uni KN, Box 188 D-78457 Konstanz http://www.basex.org

Problem with "create database"?
by Isidre Guixà 14 Feb '12

14 Feb '12

Hello! I see the command "create database" creates a database although there is another with the same name, destroying the existing one. I think that this is not normal... I've tested using the option in the GUI and also using Java client (method create in BaseXClient.java) Thanks, Isidre

gui vs. server
by Cerstin Mahlow 13 Feb '12

13 Feb '12

Hi, when displaying search results, I would like to show more or less following and preceding nodes depending on the fond node name. This works fine in the GUI using this XQuery: for $i at $p in //*[text() contains text ('Kopf' ftand 'Sand' ftand 'stecken')][self::*:p or self::*:l] let $pre := $i/preceding-sibling::*[position()<8] let $suc := $i/following-sibling::*[position()<8] return <div> {if (string(fn:node-name($i)) = "l") then $pre else "P"} {ft:mark($i [text() contains text ('Kopf' ftand 'Sand' ftand 'stecken')]) } {if (string(fn:node-name($i)) = "l") then $suc else "P"} </div> For "l"-nodes I get preceding and following nodes, for "p" nodes the "P" will be printed. However, when running the same on the server using a perl client (applying quoting for variables), I get the "P" for p-nodes but nothing for "l"-nodes. The conditional expression is correct, if I replace then $pre with then <p>LLL</p> everything works fine, "<p>LLL</p>" will be printed. If I skip the condition and allow preceding and following nodes for every $i, I get preceding and following nodes for "p"-nodes only, but not for "l"-nodes -- there is simple nothing. Is there any difference between GUI and Server? I use BaseX 7.1 beta, but I got the same effect with the BaseX 7.1 stable. Best regards Cerstin -- Dr. phil.

Problem with XMLDB in BaseX 7.0.2 and 7.1.1
by Isidre Guixà 11 Feb '12

11 Feb '12

Hello I'm trying examples XMLDB to access BaseX and none of the 3 (XMLDBCreate, XMLDBInsert, XMLDBQuery) work ok. All have the same error: Exception in thread "main" java.lang.AbstractMethodError: org.basex.api.xmldb.BXDatabase.getNames()[Ljava/lang/String; at org.xmldb.api.DatabaseManager.registerDatabase(Unknown Source) at proves.XMLDBCreate.main(XMLDBCreate.java:31) I tried it in 7.0.2 and 7.1.1 versions. Is there any solution? I found the same error reported on March 2011 for BaseX users and the response of Michael Seiferlein https://mailman.uni-konstanz.de/pipermail/basex-talk/2011-March/001395.html I am a Catalan teacher of computer science and I am writing a book on native XML DB access, among other products, and I intend to submit the BaseX local API and also XMLDB and XQJ. For the moment, it seems XMLDB is not possible? Kind Regards, Isidre Guixà

Collections and Documents
by J Gager 08 Feb '12

08 Feb '12

Hello BaseX Team, In reading the documentation and mail archives, it seems to me that BaseX does not support documents in terms of having a single URI referring to a single document node. For example, if I add a document using the db:add function: db:add("DB", document { <a/> }, "doc.xml") And subsequently attempt to retrieve it using the doc function: fn:doc("doc.xml") I get a FODC0002 error. This is discussed in the mail archives, and so far as I can tell this is because BaseX only works with collections. It does not really address the concept of a documents (excuse me if I am over simplifying the issue here). In other words, I am free to add more document nodes under the name "doc.xml" therefore it is technically a collection as opposed to a document. Is this correct? A fairly early mailing list thread from 2010-07 addresses a similar and suggests an alternative approach where one might retrieve a document in a collection as follows: for $doc in collection('DB') where matches(document-uri($doc), 'doc.xml') return $doc But, doesn't this run afoul of the W3C recommendation which states for the fn:docucument-uri function that: "In the case of a document node $D returned by the fn:doc function, or a document node at the root of a tree containing a node returned by the fn:collection function, it will always be true that either fn:document-uri($D) returns the empty sequence, or that the following expression is true: fn:doc(fn:document-uri($D)) is $D. It is implementation-defined whether this guarantee also holds for document nodes obtained by other means, for example a document node passed as the initial context node of a query or transformation." In other words, if document-uri is returning 'doc.xml' for a node in collection('DB') then I should be able to get that same document node using the doc function. I ask these questions because we are interested in being able to maintain XML artifacts as singular documents, and using the collection hierarchy to do things such as storing temporary and archived version of these artifacts. The approach we are taking right now assumes that there is only one document-node under each 'document'. I want to understand the limitations of the collection and document implementation in BaseX so that I don't make any wrong assumptions (as I think I already have). Finally, assuming the interpretations are correct, are there plans to make any changes in the implementation to support something more in line with the hierarchy of db->collection->document? I have seen in previous threads that you were seeking feedback on this, and I am curious to know if you still are. Is there a major drawback you see to this model that perhaps I have not considered? Any feedback is appreciated. Thanks, Jack Gager Metadata Technology

Use db:add from module. no updating expression allowed.
by andy 08 Feb '12

08 Feb '12

Hi! If there is a module: xquery version "1.0"; module namespace m="http://www.host.ru/xquery/m"; declare variable $m:db := "mydb"; declare function m:up() as xs:string { let $new-doc := <root-element><item>1</item></root-element> let $update := db:add($m:db, document { $new-doc }, "id1.xml") return "Result string" }; and I use it from python API or basexclient utility. Use as: xquery import module namespace m="http://www.host.ru/xquery/m" at "/tmp/test.xqy"; m:up() I get an error: Stopped at line 8, column 4 in /tmp/test.xqy: [XUST0001] Let expression: no updating expression allowed. What could be the problem? -- REGARDS, Andrey Ganyushkin
