Unknown Command let
by Sree Aurovindh Viswanathan 18 Jul '13

18 Jul '13

Hi, I am trying to use BaseX and Java. The Following is my XQuery that I am trying to run. I am using Java to run it. String query = "let $up := <food id=\"3\">\n" + " <name>Belgian Waffles</name>\n" + " <price>5.95</price>\n" + " <calories>650</calories>\n" + " </food>"; query+= "for $doc in collection('factDB/xmlDocs') for $myVar in $doc/breakfast[@menuId='3']/food[@id='6'] return insert node $up as last into $myVar"; session.execute(query); } The error I get is the following: org.basex.core.BaseXException: Stopped at line 1, column 7: Unknown command: declare. Try HELP. Can you please help me to resolve this issue. Thanks Sree Aurovindh Viswanathan

Possibly related parsing issue Re: get validate:xsd to work like validate:dtd
by Graydon Saunders 17 Jul '13

17 Jul '13

I've attached a zip file with a trivial DTD and a eleven copies of a trivial XML file that follows that DTD. If I try to create a db from this content using BaseX77-20130716.145338.zip and try to skip corrupt files (which is what I need to do on the real content; the example doesn't have any) and parse the content against entities and the DTD (something else I need to do on the real content due to a purgatory of fixed attributes), it doesn't work. SKIP INTERNAL DTDs & Collection? CORRUPT PARSER ENTITIES N N N YES Y N N YES N Y N YES Y Y N YES N N Y YES Y N Y NO! Fails! (skips all) N Y Y NO! Fails! "tiny.dtd" (Line 1): No input found Y Y Y NO! Fails as the YNY case, skipping all input files. The attached example zip has the dtd and the files and the error message as well as these results. I'd expect all of these cases to work. Thanks! -- Graydon

Basex collection size
by Sateesh 15 Jul '13

15 Jul '13

Hi basex, We are creating collections from the xml documents which we have with us,When we create a collection with xml file size of 10MB the collection size is going upto 20MB which is exactly double and some time more than double the size of xml dcuments,is there a way where we can reduce the size of collection. Also is there a way where we can extract the added xml documents from collection. Thanks & regards Sateesh.A

High cpu utilization
by Sateesh 15 Jul '13

15 Jul '13

Hi Basex, We have written a xquery which runs on a collection containing 600 xml files and the size of collection is 670MB.when we execute the xquery the CPU utilization is going up to 30-40% and as the number of hits that comes for executing this queries at a time will be around 20-40 because of high CPU utilzation for executing one query the processing speed of the remaning queries is getting delayed. Could you please check is some thing wrong in the query or do you have some suggestion which could improve the performance.Please find attachement of query and sample xml file. Thanks & regards Sateesh.A

sort bug
by Hans-Juergen Rennau 13 Jul '13

13 Jul '13

Dear Basex team, it seems to me that there is a little bug in the FLWOR sort. Code: for $i in 1 to 3 for $j in ('a', 'b', 'c') order by $i descending return concat($i, $j) Expected output: 3a 3b 3c 2a 2b 2c 1a 1b 1c Actual output: 3c 3b 3a 2a 2b 2c 1c 1b 1a Using the latest stable snapshot. Kind regards, Hans-Juergen

"XUDY0027 - Insert target must not be empty" with default namespaces
by Carlos MARCOS LAGUNAR 09 Jul '13

09 Jul '13

Hi, I'm working with latests BaseX distribution. The problem arises when I change from a specific namespace to a default namespace on the XML file. >From that moment on the insertion becomes messy, since some of them fail. Example: Here is the source XML that I insert into the newly created DataBase: <n:one xmlns:n="oneone"> <two /> </n:one> I execute then a xquery to insert a node into the empty tag "two": insert node <three/> into db:open("MyDB", "q471pa0lnovkfflso7ecsd6nj1.xml")/*:one/two In that case, I get a successful insertion: If I query the file (db:open("MyDB", "q471pa0lnovkfflso7ecsd6nj1.xml")/*:one) I get: <n:one xmlns:n="oneone"> <two> <three /> </two> </n:one> This is the normal behavior. The problem comes when I try to set that namespace as the default. So I create a new DataBase with the following XML: <one xmlns="oneone"> <two /> </one> When I try to execute the same xquery as before (insert node <three/> into db:open("MyDB", "q471pa0lnovkfflso7ecsd6nj1.xml")/*:one/two) I get the following error: rg.basex.core.BaseXException: Stopped at line 1, column 84: [XUDY0027] Insert target must not be empty I cannot understand then why the namespace affects the insertion this way :-/ I'm querying and insertion from a Java application by using JavaClient, although I guess this is not relevant here. Any help would be appreciated.

XQuery for Scala
by Charles Foster 08 Jul '13

08 Jul '13

Dear Christian, Michael, Alexander, Dirk and all at BaseX + the BaseX community. I would like to introduce you to a new XQuery API for Scala users, the XQS API! Like a lot of great software, it's tight, so tight in-fact it's 209 lines long! Oh and it's built on top of the XQJ interfaces, so it's vendor neutral. The project is hosted at: https://github.com/fancellu/xqs This was written by and is maintained by Dino Fancellu [1] who is welcoming feedback. Kind Regards, Charles [1] http://www.dinofancellu.com

Re: [basex-talk] Base-X FLOWR Expressions Not Working?
by Dirk Kirsten 05 Jul '13

05 Jul '13

Hi Raj, I am responding to the mailinglist so that maybe other people can benefit from your question as well. This is not a BaseX bug, indeed it returns the correct result. The problem is with your query and the scope of your selection. The variable $i contains the whole document, so basically it does not iterate much. You are then filtering out each document, which does not have a country with the id f0_136. As the whole factbook.xml does have one such element, it is passed on and all the country names are returned. What you instead want to do is to iterate over each country, not over each document. So the following will work as expected: for $i in doc("etc/factbook.xml")/mondial/country where $i/@id = 'f0_136' return $i/name You can also simplify this using a predicate: for $i in doc("etc/factbook.xml")/mondial/country[@id = 'f0_136'] return $i/name or even doc("etc/factbook.xml")/mondial/country[@id = 'f0_136']/name Cheers, Dirk On 07/05/2013 10:01 AM, Rajabrata Chaudhuri wrote: > Hi Dirk, > > I was hoping you could help me with a problem.
