Hello, The support of jsonp would be very welcomed here, since several projects on tge-adonis use or will use the basex.tge-adonis.fr/rest service... For now, I went on with the proxy solution : http://hyperdonat.tge-adonis.fr/basex/basex.html Cheers, Maud On Sat, Oct 22, 2011 at 12:07 AM, < basex-talk-request(a)mailman.uni-konstanz.de> wrote: > Send BaseX-Talk mailing list submissions to > basex-talk(a)mailman.uni-konstanz.de > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.uni-konstanz.de/mailman/listinfo/basex-talk > or, via email, send a message with subject or body 'help' to > basex-talk-request(a)mailman.uni-konstanz.de > > You can reach the person managing the list at > basex-talk-owner(a)mailman.uni-konstanz.de > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of BaseX-Talk digest..." > > > Today's Topics: > > 1.

Hello everybody, I am very new at BaseX http server, and at jQuery, and at this mailing list too :) Concerning the error you got Colin : thrown error: [Exception... "Access to restricted URI denied" code: "1012"... I suddenly have the same problem though basex and my files have the same domain : http://hyperdonat.tge-adonis.fr/basex/basex.html (The basex server is here : http://basex.tge-adonis.fr/rest) I had other problems before this with my script, but not this one, and I don't know what I did that produced it...

Query / Iteration on server side.
by Fabian Hickert 29 Nov '11

29 Nov '11

Hi all, I was playing with the python examples of basex version 6.7.1-1 from the debian-wheezy repository. I've used the corresponding BaseXClient.py to establish a connection/add/update/query stuff and so on, it worked very well. Now I've noticed the new 7.0.2 version and now I've got problems with the query/iterate operation. In the 6.7 example one starts a query and iterates over the results, using the more method, which sends \x01 followed by the query-result id. But the examples of 7.0.2 don't behave like this anymore, instead they cache the complete result on the client side. I've tried to rebuild the old 6.7 behaviour with the commands shown here, http://docs.basex.org/wiki/Server_Protocol but I wasn't successful. Is is still possible to query and iterate on the server side instead, of caching the complete result on the client side? Am I doing things the wrong way? If I do, could you please point me to the right direction or examples, documentation?

Question about the Fulltext search!
by Truong An Nguyen 29 Nov '11

29 Nov '11

Hi, I've two questions about the fulltext search. 1) I've created fulltext i for my BaseX doesn't understand ftcontains. When I try a CONTAINS query in a 1 Gigabyte Database, using text index is slower than without text index. How can I use fulltext index rightly? 2) Does BaseX supports regular expression in the fulltext extension? If yes, could you please give me an example. Thanks Cheers, An

how does one output the first line?
by jidanni＠jidanni.org 28 Nov '11

28 Nov '11

Hello, We read "The PITarget of a processing instruction may not consist of the characters "XML" in any combination of upper and lower case. The DirPIContents of a processing instruction may not contain the string "?>"." So how can one output the line <?xml version="1.0" encoding="UTF-8"?> I need to put it at the top of my output. Also, is there a way to only write the fn:matches line once here?: let $d := doc("p.xml") let $region := ('基隆|新北|台北','桃園|新竹|苗栗','台中|彰化|南投','雲林|嘉義|台南', '高雄|屏東','宜蘭|花蓮|台東','澎湖|金門|連江') for $count in 1 to count($region) return <Folder> <name>{$region[$count]}({count($d/Folder/Placemark[fn:matches(./description, concat('/li><li>','(',$region[$count],')'))])})</name> <open>0</open> {$d/Folder/Placemark[fn:matches(./description, concat('/li><li>','(',$region[$count],')'))]} </Folder> Also, in perl one can use decode_entities() to convert < to < etc., however reading http://www.w3.org/TR/xpath-functions/ one notes xquery has no such function. What if I want to reduce my output by using CDATA instead? Or maybe xquery output must be valid XML no ifs ands or buts.

insert node takes really long to complete
by Jan Vlčinský (CAD) 27 Nov '11

27 Nov '11

Hi I am trying to add some attribute into my data, doing it this way: for $msg in //MSG let $evi := $msg//TMCE/EVI[1] let $updclass := $evi/@updateclass let $tmcloc := $msg//MLOC/TMCL[1] let $dir := $tmcloc/@direction let $loccode := $tmcloc/@primarycode let $alertc-id := concat($loccode, $dir, $updclass) return insert node (attribute alertc-id {$alertc-id}) into $msg If I simply return result similar to this, using following query: for $msg in //MSG let $evi := $msg//TMCE/EVI[1] let $updclass := $evi/@updateclass let $tmcloc := $msg//MLOC/TMCL[1] let $dir := $tmcloc/@direction let $loccode := $tmcloc/@primarycode let $alertc-id := concat($loccode, $dir, $updclass) return element enhancedmsg {attribute alertc-id {$alertc-id}, $msg} it takes just 27 s With the insert node, it takes for ever, I had to cancel the query after 90 minutes. I wonder, if there is any relation between this long execution time and possible inefficiency with automatic index update (but I am not aware of what is current status of this approach). Currently, I see, it would be much more efficient to output the result as files, and then import them back, as importing the data I am working on took just 2 minutes. Attached are few sample xml files in the format, I use in my database. Real database consists of 129097 MSG elements and number of DOC elements and documents is exactly the same.

why do I have to strip all the namespaces?
by jidanni＠jidanni.org 27 Nov '11

27 Nov '11

Dear Sirs, It is driving me nuts. You see all the basex examples here on Debian, only have simple examples, with no NAMESPACES involved. However, http://gdata.youtube.com/feeds/api/playlists/1ADE82BB5C96D594?prettyprint=t… is the kind of data I am trying to deal with. Yes, you could say just do $ sed '2s/.*/<feed>/' and strip the namespaces. Ha ha ha. Well I did. And then there is media:* how do I deal with that. sed s/:// ? So instead I tried to look up how do declare namespaces. But I could never mind. Here's my makefile N=\ declare namespace atom='http://www.w3.org/2005/Atom';\ declare namespace app='http://purl.org/atom/app#';\ declare namespace media='http://search.yahoo.com/mrss/';\ declare namespace openSearch='http://a9.com/-/spec/opensearchrss/1.0/';\ declare namespace gd='http://schemas.google.com/g/2005';\ declare namespace gml='http://www.opengis.net/gml';\ declare namespace yt='http://gdata.youtube.com/schemas/2007';\ declare namespace georss='http://www.georss.org/georss'; F=1ADE82BB5C96D594?prettyprint=true P=http://gdata.youtube.com/feeds/api/playlists/$F s1:;basex -Vc "OPEN input; XQUERY $N " strippedF:$F;sed '2s/.*/<feed>/' $? |basex -Vc "CREATE DB input /dev/stdin; XQUERY /" xm:$F;basex -Vc "OPEN input; XQUERY (: xmlns:atom='http://www.w3.org/2005/Atom':) /*:feed" 1m:$F;basex -c "OPEN input; XQUERY declare copy-namespaces no-preserve,inherit;//*[local-name()='thumbnail']"|sed q edwm:$F;basex -Vc "OPEN input; XQUERY declare default element namespace 'ccc';//*[local-name()='thumbnail']" wm:$F;basex -Vc "OPEN input; XQUERY /*[local-name()='feed']/*[local-name()='entry']" m:$F;basex -Vc "OPEN input; XQUERY data(/*:feed/*:entry/*:id)"|tr ' ' \\n m1:$F;basex -Vc "OPEN input; XQUERY /*:feed" c:$F;basex -Vc "OPEN input; XQUERY data(//*:name)[1]" c1:$F;basex -Vc "OPEN input; XQUERY (//*:name)[1]" b:$F;basex -Vc "CREATE DB input $?; XQUERY /" My question: is it possible to use basex reasonably here shedding it of all the namespace baggage that I can not deal with. Thanks.

Is there a particular reason why I can't do this (mixing let with copy/modify): declare namespace ddi = "http://www.icpsr.umich.edu/DDI"; let $codeBook := collection()[1]/ddi:codeBook let $titlStmt := $codeBook/ddi:stdyDscr/ddi:citation/ddi:titlStmt copy $titlStmt1 := $titlStmt modify ( rename node $titlStmt1 as QName('http://www.icpsr.umich.edu/DDI','CopyOfTitlStmt') ) return $titlStmt1 but this works: declare namespace ddi = "http://www.icpsr.umich.edu/DDI"; copy $titlStmt1 := collection()[1]/ddi:codeBook/ddi:stdyDscr/ddi:citation/ddi:titlStmt modify ( rename node $titlStmt1 as QName('http://www.icpsr.umich.edu/DDI','CopyOfTitlStmt') ) return $titlStmt1 thanks *P
