Re: [basex-talk] Sub : Adding Special Characters to the Collection Database

Hi Madhan, I see you are using BaseX 7.9. Does the problem persist when using our latest release? What is the output of db:info() (or INFO DB)?

Hi Christian, that's what I was afraid, http://www.w3.org/TR/xslt-30/#func-xml-to-json is just too complex to understand for me.

basic JSON problem
by Florent Gallaire 09 Nov '15

09 Nov '15

I would like to use the new "basic" JSON via REST. With basex 8.3.1 and 8.3.2beta, my_request&method=json&json=format=jsonml works fine, but my_request&method=json&json=format=basic returns : [FOJS0006] Element 'article' has invalid namespace: ''. What's the problem ? Best regards Florent -- FLOSS Engineer & Lawyer

Keeping a database optimized
by Paul Swennenhuis 05 Nov '15

05 Nov '15

What is the best way to keep the indexes of a database up-to-date? I have created a database with the option UPDINDEX set to ON (and db-info tells me that it is indeed switched on) and I have also created text and attribute indexes. Even so, after several insertions (using XQUERY insert node) I see that the UPTODATE flag is no longer checked and I have to run OPTIMIZE ALL to get back my performance. a) Is there a way to keep UPTODATE checked under all circumstances? And if not b) Is is advisable to run OPTIMIZE ALL after every insertion? (I guess not)

request concerning unittest in the GUI
by Rob Stapper 02 Nov '15

02 Nov '15

Hi Christian, For debugging my xquery-code I using the test-facilities from the unit-module in combination with trace and prof:dump command in the code for code-tracing. The problem is that when a unit-test fails it overwrites the trace-output in the Query-info window. So the code-tracing-info is gone just when I need it. It would make debugging a lot easier if the trace-output is appended after the unit-test-output in the Info-window of the GUI.

Best way to batch up a set of DB creates, updates and queries?
by Hondros, Constantine (ELS-AMS) 01 Nov '15

01 Nov '15

I'm looking for the best way to batch up a series of updating operations into a single pipeline that can be run at once. To give you an idea, we have to create multiple databases, perform a number of updating post-processes on each, before finally pulling certain fields out. I've got a lot of parameters that need to externalised somehow - database creation options, location of DTDs, XSDs, Catalogs, and unless I am trying this the wrong way I am finding it quite difficult. I can't write it all XQuery - I have a mixture of updating and non-updating functions. I can't get much traction out of the BXS scripting syntax - for example, I can't seem to create and use variables using this. What do other people out there use to glue these sorts of operations together? TIA, Constantine ________________________________ Elsevier B.V.
