XPath generator
by Giuseppe Celano 17 Nov '17

Hi All, I would like to ask what the best way is in BaseX to create XPath expressions once I identify a certain span in an XML file. More concretely, I usually tokenize a text contained in an XML document, and I would like to specify for each token its position in the original document. Thanks. Best, Giuseppe

Hypertext Application Language: Do we need a library that implements this?
by Omar Siam 17 Nov '17

Hi list! I implemented a REST API using apigility some time ago and by doing that I stumbled upon http://stateless.co/hal_specification.html I kind of like it so I thought maybe there is a customizable XQuery implementation? If not: Is someone else interested in creating a customizable BaseX XQuery implementation? Best regards Omar Siam

basex-node binding objects
by E. Wray Johnson 15 Nov '17

Andy, 1. I am pelase that JSON result objects are mapped to JavaScript objects. Are undefined values handled (e.g. XQuery () vs JavaScript undefined)? 2. I am using basex-node and having trouble binding objects in a query. I would like to have the object result in an XQUERY map. It would be nice if undefined values as defined above are handled as well. For now I have to do something like this'$x := map ' +JSON.stringify(obj).replace('undefined', '()'). I hope this make sense.

BaseX gui, windows 10 and java
by Arto Viitanen 15 Nov '17

I have BaseX 8.6.7 on 32 bit Windows 10. When I tried to load an XML file yesterday to editor, the program crashed. I tried several times, and then reinstalled BaseX from net. This did not help. The program crashes on file dialog. If I open the file with double click, the file opens. Then I reinstalled java, but this did not help either.When I used cmd window, and run "java -cp BaseX.jar org.basex.BasexGUI", it worked. So it seems problem is on Java version embedded. Windows is 10.0.16299.19, and Java that works is 1.8.0_144-b01 Arto Viitanen Microteam Oy Haarlankatu 4B 33230 Tampere

DB locking
by Navin Rawat 14 Nov '17

Hi There, I have created an script which will setup a job by job:eval() function of BaseX to perform multiple actions on the inputs before ingesting them into the database. I have to create a report on each and every success/failure steps on each job. For this I have created per job XML file within the database under '/job/' directory, it is an update function. Everything is working fine, except user is unable to perform any other action within the database at the time of job execution. It seems, our running job is blocking whole database. Our job may take 20 minute to 2 hour to finish. Is this the correct behavior of BaseX to block whole database (even for reading)? or I am doing something wrong? Please suggest. Regards, Navin

Update operations on JSON objects are not working
by E. Wray Johnson 13 Nov '17

13 Nov '17

I have tried many ways of updating JSON objects and none seem to work. Using the BaseX GUI, the Result window seems to show the correct outcom, but the database is not modified. What am I missing? Do I need to explicitly start/stop a transaction? XQUERY: db:open('db','country')/json[countryId = 1] update { replace value of node countryName with 'Aldorria', insert node <population type="number">1000</population> into . } Result: <json type="object"> <countryId type="number">1</countryId > <countryName>Aldorria</countryName> <population type="number">1234</population> <planetName>Zeldon</planetName> </json>

XSD 1.1 support? Unknown function: xs:dateTimeStamp
by Bridger Dyson-Smith 13 Nov '17

13 Nov '17

Hi Christian, et al, I was wondering if I'm seeing a bug or an oversight on my part. I was trying to type a $date as xs:dateTimeStamp but getting an error using the BaseX GUI, v8.6.7. let $date := '2017-12-15T23:45:00-5:00' return xs:dateTimeStamp($date) I've read in Walmsley's that XSD v1.1 data type support is required for xs:dateTimeStamp. Is this a bug or maybe user/operator error? Many thanks. Best, Bridger
