how to start and configure Jetty?
by Nicholas 22 Jun '20

22 Jun '20

I don't quite understand what it means for Jetty to be "embedded" in or with BaseX, but presumably there's a configuration? I see: |DEBUG =falseDBPATH =/home/nicholas/basex/data LOGPATH =.logs REPOPATH =/home/nicholas/basex/repo LANG =EnglishLANGKEYS =falseFAIRLOCK =falseCACHETIMEOUT =3600#Client/ServerArchitectureHOST =localhost PORT =1984SERVERPORT =1984USER =PASSWORD =SERVERHOST =PROXYHOST =PROXYPORT =0NONPROXYHOSTS =IGNORECERT =falseIGNOREHOSTNAME =falseTIMEOUT =30KEEPALIVE =600PARALLEL =8LOG =trueLOGMSGMAXLEN =1000#HTTP ServicesWEBPATH =/home/nicholas/basex/webapp RESTPATH =RESTXQPATH =PARSERESTXQ =3HTTPLOCAL =falseSTOPPORT =8985AUTHMETHOD =Basic but there's nothing actually at WEBPATH, no directory. Perhaps RESTXQPATH requires configuration? Really, just guessing. See also: https://askubuntu.com/q/1252599/847449 If I installed BaseX with apt, should it also pull in Jetty, then? thanks, Nick |

trying to rename all node elements from <foo/> to <bar/>
by Nicholas 21 Jun '20

21 Jun '20

Hi, How do I rename all the "record" nodes in a database? I'm trying: for $x in db:open("bccdc_covid19") return return rename node $x//record as "baz" but this gives back Stopped at ., 1/13: [XPDY0002] bc.rename.xq: no context value bound. or [XPST0003] Unexpected end of query: 'rename node $x/...'. depending whether it's run from within the basex console. thanks, Nick

sum() is returning inaccurate sums
by Jay Straw 17 Jun '20

17 Jun '20

Hi all, I'm building a budgeting system for home use, using XSLTForms and -- ready for it? -- BaseX! sum() has been behaving weird. I'm adding USD, which means only 2 decimals of precision. But depending on the combination of elements I add, I'll get a long double that's inaccurate. Sometimes it returns what I expect, sometimes it doesn't, but either case is repeatable. Take these 3 receipts: 1 -- <receipt uuid="694bf777-2d40-42ad-9809-97dfe6b04f40"> <metadata> <date>2020-06-08</date> <store> <name>Frigid North</name> <location/> </store> <purchaser>Jay</purchaser> <account>Debit</account> <category>shop-general</category> <net-total-computed>6.50</net-total-computed> <tip>0.00</tip> <gross>6.50</gross> </metadata> <item> <name>Start Capacitor (for old rockwell saw/jointer motor)</name> <cost>6.50</cost> <qty>1</qty> <total>6.50</total> <category>shop-general</category> </item> </receipt> 2 -- <receipt uuid="2eb74e82-3db5-4bd9-a591-8621c79f3fd6"> <metadata> <date>2020-06-09</date> <store> <name>Home Depot</name> <location>Tudor</location> </store> <purchaser>Jay</purchaser> <account>Cash</account> <category>jay-misc</category> <net-total-computed>9.87</net-total-computed> <tip>0</tip> <gross>9.87</gross> </metadata> <item> <name>Stainless Protractor</name> <cost>9.87</cost> <qty>1</qty> <total>9.87</total> <category>jay-misc</category> </item> </receipt> 3 -- <receipt uuid="1f1462e6-b37f-4daa-b293-29b9ec353627"> <metadata> <date>2018-09-16</date> <store> <name>Title Wave</name> <location>Midtown</location> </store> <purchaser>Franny</purchaser> <account>Debit</account> <category>books</category> <net-total-computed>20.85</net-total-computed> <tip/> <gross>20.85</gross> </metadata> <item> <name>Music of the Spheres</name> <category>books</category> <cost>6.95</cost> <qty>1</qty> <total>6.95</total> </item> <item> <name>Magic Mirror of M.

I did find one other thread in the mailing list about this, it got an answer but didn't really explain much. I have a schema for prices in the XForm, should I be loading that somehow? The only workaround I have now is like, "let $grosses:= for $gross in $receipts//gross return xs:decimal($gross)" but I'm hoping there's a more straightforward way. Not sure if this is implementation specific or if it's not defined or what. If I should ask elsewhere, please let me know :-) Be well, Jay

Writing 
by Giuseppe G. A. Celano 11 Jun '20

11 Jun '20

Hi, I would like to print a comment containing only a dash (i.e., ) , but this is not allowed. I tried to use "-" instead of - in comment { "-” }, but such a string is converted to ‘-', so the error is still there. How can I print  ? Should I simply use <----->? In any case, I see that data() does not convert - into -: how can I get the conversion? Thanks. Best, Giuseppe

RestXQ and Docker
by Hinkelmanns Peter 11 Jun '20

11 Jun '20

Dear list, I'm using BaseX in a Docker container and I am able to add XML-Files to Databases. But I am not allowed to edit 'restxq.xqm' or to add something to the '/webapp' directory. Changing permissions with 'chown -R 1984 ~/webapp/' via bash doesn't work. What do I need to do, to be able to use my own restxq-module within the docker container of basex? Thanks in advance Peter <https://twitter.com/MHD_BDB>

S1000D XML Database
by Roger Jerrell 08 Jun '20

08 Jun '20

I am completely new to basex so forgive me please for asking something that has been asked before. Can anyone share any knowledge about the use of basex to manage S1000D XML content? Specifically, I'm interested in it's use as an offline xml database manager for a large collection of S1000D data modules: 100k or more perhaps 5GB of data uncompressed. Any comments or thoughts or tips are greatly welcomed and appreciated. Roger Technical Publications Engineer Renton, WA, USA

GUI Stack Trace
by Ben Pracht 08 Jun '20

08 Jun '20

Hi Folks, I got this error trying to specify a directory location when creating a database using the GUI by dialog. Creating the database via command works. I feel like this is somehow not the fault of BaseX because I don't see this on my other Linux machine. Nonetheless, I'd like recommendations on how the Linux side of the basex community works.

Serializing with xml-stylesheet prolog
by Jay Straw 07 Jun '20

07 Jun '20

Hi, Been a while since I've posted. Been a while since I programmed! I need to run a client-side stylesheet (XSLTForms, I tried it server side, didn't work), but getting my assembled XHTML document to output with <?xml-stylesheet ...?> has been hard. After searching https://docs.basex.org/wiki/Serialization, http://www.w3.org/TR/xslt-xquery-serialization-31/#serparams-in-xdm-instance, searching this list, lots of googling with prolog/declaration/other words, I came up empty. So I tried other things. But those other things worked poorly, and when things did come out in the right order, with the right namespaces etc, the single page app that worked as a standalone document, doesn't work. If I copy and paste raw output from basex that my browser receives, put it in a new file in the same directory, and open that in my browser it works fine. So there's gotta be some issue with my workaround. So I'm hoping you can tell me what I've missed in my searches, so that I don't need a workaround :-) I haven't built anything in a few years, but I've been subscribed to this list for many many years and you're all such a patient, wonderful lot. Thank you all so much. Be well, Jay Straw

java.lang.ArrayIndexOutOfBoundsException on REST GETrequest
by Geoff Alexander 06 Jun '20

06 Jun '20

We have a BaseX application that uses the BaseX REST API. A number of GET requests are failing with an HTTP 400 Bad Request response. Looking at the BaseX logs, I find that BaseX is internally throwing java.lang.ArrayIndexOutOfBoundsException for these HTTP 400 Bad Request failures: <entry time="05:13:57.193" address="***.***.***.***:*****" user="admin" type="400" ms="3.93">[GET] https://********.*******.ibm.com:10443/BaseX/rest/****/*******.xml; Improper use? Potential bug? Your feedback is welcome: Contact: basex-talk(a)mailman.uni-konstanz.de Version: BaseX 8.6.7 Java: IBM Corporation, 1.8.0_241 OS: Linux, amd64 Stack Trace: java.lang.ArrayIndexOutOfBoundsException at org.basex.util.Compress.unpack(Compress.java:120) at org.basex.data.DiskData.txt(DiskData.java:284) at org.basex.data.DiskData.text(DiskData.java:251) at org.basex.io.serial.Serializer.node(Serializer.java:370) at org.basex.io.serial.Serializer.node(Serializer.java:158) at org.basex.io.serial.StandardSerializer.node(StandardSerializer.java:105) at org.basex.io.serial.Serializer.node(Serializer.java:345) at org.basex.io.serial.Serializer.node(Serializer.java:158) at org.basex.io.serial.StandardSerializer.node(StandardSerializer.java:105) at org.basex.io.serial.AdaptiveSerializer.node (AdaptiveSerializer.java:75) at org.basex.io.serial.Serializer.serialize (Serializer.java:109) at org.basex.io.serial.AdaptiveSerializer.serialize (AdaptiveSerializer.java:66) at org....</entry> I realize that BaseX 8.6.7 is somewhat old. I can look at upgrading to a more recent version if necessary. But before I do that, I'd like to know if the java.lang.ArrayIndexOutOfBoundsException is a known problem and more importantly if there is anything we can do short of upgrading BaseX to fix the problem. Thanks, Geoff Alexander, Ph.D. Software Engineer, Corporate Tools Development IBM Corporation Charlotte, NC
