Re: [basex-talk] Basic query

Hi Christian, Thank you for looking at the query. You are always a great help! The result I am looking for is the total number of occurences. Because there is such a large repository of letters. With this number I am able to say that the word 'zonnebloemen' occurs 30 times in all documents. For example. I thought this could be accomplished with a small alteration of this query. If you see a solution that would be great, otherwise I just count them by hand.

adding zip contents – bug or feature?
by Imsieke, Gerrit, le-tex 25 May '11

25 May '11

When I add a directory to a database in 6.6.1 using the plain *.xml createfilter, and when there's a zip file below this directory, the zip file's contents will be indexed, too, as if they reside in the server's working directory. If this is a feature, how can I switch it off? Gerrit

External variables in GUI
by Mike Rothon 24 May '11

24 May '11

Firstly I apologise if this has been asked before, but I cannot work out how to search this mailing list without downloading all the archives first. I am working through the XQuery in 10 minutes tutorial and trying this XQuery: declare variable $firstName as xs:string external; <videos featuring="{$firstName}"> { let $doc := doc('http://www.stylusstudio.com/examples/videos.xml') for $v in $doc//video, $a in $doc//actors/actor where ends-with($a, $firstName) and $v/actorRef = $a/@id order by $v/year return <video year="{$v/year}"> {$v/title} </video> } </videos> It's fine in standalone mode (command line), but I cannot find a way of supplying an external variable in the GUI. Thanks and regards.

Re: [basex-talk] base-uri and put statement

Hi Sebastian, thanks again for your report. There's a problem with the implementation of fn:put as the current solution based on Java FileOutputStream can't handle the kind of URI we discussed earlier [1]. We'll let you know as soon as we fixed this issue.

base-uri and put statement
by Sebastian.Wiemer＠Bertelsmann.de 24 May '11

24 May '11

Hello, In an fn:put(TempNode,URI) I would expect base-uri(Node) as a URI parameter to work. But base-uri(Node) returns on Windows "file:/C:/somepath/somefile.xml", which does not work, because the URI cannot be opened. The URI "/somepath/somefile.xml" works. And file://C/somepath/somefile.xml does also work. Is this a bug? example: let $doc:= doc("bla.xml") put( copy $temp := $doc modify replace value of node $temp/n with lower-case($temp/n) return $temp,base-uri($doc) ) (: this does not work, but should it not? :) best regards, Sebastian

Fwd: Incorrect implementation of XQUF?
by software developer 23 May '11

23 May '11

Hi, All I did was upgrade from 6.5.1 to 6.6.3-SNAPSHOT which I took from BaseX file-server today (a couple of hours ago) and I get: Not expected (Data Access out of bounds [pre:2050100, indexSize:8028, access:8028 > 8027] This is quite similar to the issue I faced when I raised the original query regarding XQUF (this thread). Immediately downgraded to 6.5.1 and the issue got fixed (I did not update the data at all). Thanks.

(Poss.) Bug Report BaseX 6.6.2
by Loyde Yates 22 May '11

22 May '11

Dear BaseX, Don't know if this is important. I'm new to BaseX, but I thought I should relay the entry I received when attempting to download info into BaseX. The six previsous files seem to load okay. I still have to learn more to make that determination. Thanks for making the software available! Loyde Yates Error: Possible bug?
