Re: [basex-talk] BaseX-Talk Digest, Vol 167, Issue 9

Hi Christian, Thnx. You made me a bit worrying there. Just a thought: shouldn’t util:if not just be part of the regular BaseX syntax? Together with fn:for-each, the fn:fold functions and hof:fold-left1, they represent the group of procesflow-controll-functions.

Debugging XML catalog with BaseX 10.7
by Andy Bunce 23 Nov '23

23 Nov '23

Hi, I am following the guide at [1] with the aim of loading some XML with a variety of DTD doctypes. I have a catalog.xml set (which works in another app) and in lib/custom I have - saxon-he-10.9.jar - xmlresolver-5.2.2-data.jar - xmlresolver-5.2.2.jar - xmlresolver.properties It is not working as I hoped. Is there a way to get debug info from xmlresolver to a file without going to the Java level? The guide says "You must configure your environment with an appropriate logging backend." [2] I guess this is about SLF4J <http://www.slf4j.org/> but I have no experience here. /Andy [1] https://docs.basex.org/wiki/Catalog_Resolver [2] https://xmlresolver.org/ch06#xml.catalog.defaultLoggerLogLevel

BaseX 10.7 and util:if
by Andy Bunce 23 Nov '23

23 Nov '23

Hi, The documentation for the utility module [1] says certain functions will be removed in version 11 because they will be in XPath 4.0. However, util:if has been removed from the documentation and I think there is no equivalent function in this case. util:if is an alternative syntax for the BaseX Ternary operator [2]. ( I have used it because it was easier than trying to get my XQuery parser EBNF to accept $ok ?? 1 !! 0 etc) Is util:if to be removed? /Andy [1] https://docs.basex.org/wiki/Utility_Module#util:if [2] https://docs.basex.org/wiki/XQuery_Extensions#Ternary_If

Issue in BaseX 11.0 beta
by Thompson, Timothy 23 Nov '23

23 Nov '23

Hello, In BaseX 11.0 beta, I’m encountering a strange error. I’ve created a gist that illustrates the behavior: https://gist.github.com/timathom/7fd44b43de1fa72162cd59cf755c3d91. I have a series of maps that I want to check against a lookup index and then filter the results. I’m setting a Boolean variable that only seems to get applied if I reference it within the then statement. I’ve tested the query in an earlier BaseX version (10.6), and it produces the expected result (without referencing the Boolean variable again). Thanks in advance, Tim -- Tim A.

Re: [basex-talk] BaseX 10.7 and util:if (Christian Gr?n)
by Rob Stapper 22 Nov '23

22 Nov '23

Christian, I really hope you will change your mind about this. In BaseX, as a function development environment, all structural constructs such as: “if then else” should be available as functions. Personally: as a functiondevelopmentjunky, I took a lot of effort replacing all ifThenElse-constructs into util:if-functions. I really would be disappointed if structural constructs aren’t available as functions in BaseX. Hope you’ll change your mind about this point.

I?ve revised the documentation. One property of util:if was that you could omit the argument for the else branch. We decided to drop util:if, because the specification now provides a new syntax for if expressions where the else branch is optional: if ($test) { $then } if ($test) { $then } else { $else } The ternary operator was temporarily added to the spec as an official feature, but we eventually dropped it again to reduce the number of different notations for existing features (unfortunately, the popular A ? B : C syntax was no option, as ? is already used for lookups).

Bug in parse-xml-fragment() and ampersand entity?
by Zimmel, Daniel 22 Nov '23

22 Nov '23

Hi, is this a bug? Query: parse-xml-fragment('Tom & Jerry') Result: Tom ? Jerry Same result with: parse-xml-fragment('Tom &DUMMY; Jerry') BaseX 10.7 Saxon complains correctly that the resulting document node is not well-formed. BaseX should also return an error, shouldn't it? Best, Daniel

The duration of a cached job
by Andy Bunce 22 Nov '23

22 Nov '23

Hi, Back in the winter of 2017, BaseX 8.6 , I reported an issue with job duration [1] A question about jobs:list-details[2] I had expected the attribute duration: evaluation time (for running and cached jobs) to be frozen once the job is cached. Using BaseX 10.7 it seems this issue is back ``` job:eval("42",(),map{"cache":true()}) job24 job:list-details("job24") <job id="job24" type="QueryJob" state="cached" user="admin" duration="PT39.031S" reads="(none)" writes="(none)" time="2023-11-20T11:23:44.133Z">42</job> job:list-details("job24") <job id="job24" type="QueryJob" state="cached" user="admin" duration="PT2M35.894S" reads="(none)" writes="(none)" time="2023-11-20T11:23:44.133Z">42</job> ``` /Andy [1] https://www.mail-archive.com/basex-talk@mailman.uni-konstanz.de/msg09036.ht… [2] https://docs.basex.org/wiki/Job_Module#job:list-details <https://docs.basex.org/wiki/Job_Module#job:list-details>

Bug in fn:fold-right?
by Thompson, Timothy 21 Nov '23

21 Nov '23

Greetings, I noticed that there seems to be an issue with fn:fold-right in BaseX (10.8 beta). When I pass it a sequence of elements, they do not get atomized/accumulated. Example: let $data := <data> <a>a</a> <b>b</b> <c>c</c> </data> return <test>{ fold-right( $data/*, "", concat(?, ".", ?) ) }</test> returns: <test/> The same query in Saxon-HE 11.4 returns: <test>a.b.c.</test> Best regards, Tim -- Tim A.

Dear Joe, Thanks for the report,I haven’t upgraded to Sonoma yet, but will this afternoon :) I will try to reproduce the error and come back to the list. :-) Best Michael Am 24.10.2023 um 13:40 schrieb Joe Wicentowski <joewiz(a)gmail.com>: Hi all, I am experiencing a crash when starting basexgui.
