Re: [basex-talk] Select proper database for Plot Widget
by Christian Grün 09 Jan '23

09 Jan '23

Hi Ben, My recommended solution (albeit a bit static) is to generate a new XML document that contains attributes or elements with the relevant data, create a database from it, and open the plot for that database. Hope this helps, Christian On Sun, Jan 8, 2023 at 12:23 AM Ben Pracht <ben.pracht.news(a)gmail.com> wrote: > > Christian, > I like the chart type.

DBA: upload of database backups
by Andy Bunce 09 Jan '23

09 Jan '23

Hi, Since around 9.7 the DBA has an option to upload backup zip files. However it appears the backups are uploaded to data/.dba rather than data/ so can not be restored via the DBA UI. Maybe the problem is here [1] /Andy [1] https://github.com/BaseXdb/basex/blob/main/basex-api/src/main/webapp/dba/da…

Select proper database for Plot Widget
by Ben Pracht 07 Jan '23

07 Jan '23

I like having a convenient inline plotting for data, but I can't figure out how to select the right database to query from for the BaseX GUI plot widget. I can only select X and Y values from what I think is the country database. Best Regards, Ben Pracht 919.809.2439 ben.pracht(a)gmail.com

Hi Chandrasekhar (cc to the list), Can the behavior be reproduced with the latest version of BaseX?

Plot visualization of unstructured data
by Marco Asa 01 Jan '23

01 Jan '23

Hello Everyone, I'm quite new to all of this but I am trying to setup a database in XML for logging some process data and I am planning to use baseX for polling Xqueries. While testing BaseX i was also amazed by the visualization functions, I have however a doubt on plot which can be easily explained looking at the screenshot at this link <https://photos.app.goo.gl/P2kETJLZoxWBhFHe8> In the data tree you can see I have two branches which present both the attributes @BE_T and @stress_as_grown. In the plot nonetheless only the point corresponding to the values of the first branch is shown. At the contrary, the explorer window present both pairs of values. Is there any way I can plot all the occurences of the selected attrubutes and not just the first one occurring?. Thanks for your help, Best regards, -- Lucas

Possible to get line number of node?
by Eliot Kimber 22 Dec '22

22 Dec '22

I’m pretty sure the answer is “no”, but is there any way from BaseX 9.6 to get the source line number a given node starts on? My use case is I’m looking for specific elements and making a report of documents that contain them and identifying information about the elements to help with finding them outside of BaseX (i.e., in Oxygen where the authoring happens). I’m parsing with the “trim whitespace” option turned off and I’m not doing any DTD-aware parsing, so the elements as loaded into the database will match the source (no additional attributes or anything). So at least in theory BaseX could maintain accurate line numbers. These elements don’t have @id attributes so no natural way to identify them, so it would be useful to be able to report the source line number as a guide to people fixing these elements. I didn’t see anything in the docs so I thought I’d ask just in case I’ve missed some trick. Thanks, E. _____________________________________________ Eliot Kimber Sr Staff Content Engineer O: 512 554 9368 M: 512 554 9368 servicenow.com<https://www.servicenow.com> LinkedIn<https://www.linkedin.com/company/servicenow> | Twitter<https://twitter.com/servicenow> | YouTube<https://www.youtube.com/user/servicenowinc> | Facebook<https://www.facebook.com/servicenow>

Scope of a xPath variable
by Leo Studer 20 Dec '22

20 Dec '22

Hello Cracks ;-) In the code below I encounter the problem, that I have to define the same xPath function variable $organizations twice and I do not understand why. Running the code with the newest versions of BaseX or with Saxon EE, I get a runtime error when I leave the second definition of $organizations out. Any explanation? Thanks in advance. Happy Holidays Always, Leo xquery version "3.1" encoding "UTF-8"; declare variable $doc := doc("factbook.xml"); element Memberships { let $membershipPotentcy := function($orgs){if (count($orgs)le 0) then 'none' else if (count($orgs) le 5) then 'few' else 'many'} let $organizations := function($country){$doc//organization[members/@country = $country/@id]/@abbrev/string(.)} for $countries in $doc//country group by $mp:= $membershipPotentcy($organizations($countries)) order by $mp return element {$mp} { for $country in $countries let $organizations := function($country){$doc//organization[members/@country = $country/@id]/@abbrev/string(.)} order by $country/@name return <country>{$country/@name, $organizations($country)}</country> }}

What ever happened to the idea of exposing BaseX+FS as a Fuse filesystem?
by Alejandro Garcia 19 Dec '22

19 Dec '22

I've been reading Alexander Holupirek, 2012: Declarative Access to Filesystem Data Thesis and I think it is very interesting and very relevant today in an era of people wanting to build a "second brain". Thanks in advance
