Options for ft:search
by Sebastian Zimmer 15 Mar '21

15 Mar '21

Hi, I'd like to request a feature concerning the ft:search method: An `lserror` option that works exactly like the global option `LSERROR`. It would be nice if we could set the maximum Levenshtein distance specifically for each fuzzy search without having to adjust the global option. Another question on ft:search: Is there a reason why it doesn't have a `case` option just like ft:contains has one? Best regards, Sebastian

Feature Request: Save untitled, open scripts when exiting GUI
by Andreas Mixich 30 Jul '20

30 Jul '20

SublimeText has this nifty feature, that it saves all open tabs, even if the have no representation on the filesystem, so one can continue exactly, where one has left off. I find myself often to have several, unnamed, XQueries open, to test this concept, to compose that function, etc. It would be nice, if one could simply shut off and have them reopened next time without naming a file and saving each item in question. -- Minden jót, all the best, Alles Gute, Andreas Mixich

Storing xml message
by Ramzi Hammouda 08 May '20

08 May '20

Hello, First, thanks for the effort you're putting it to help BaseX users. I'm Using POST method to update BaseX database, I want to insert an xml node to an existing document calastone.xml in calastone database , if the node contains '<', it returns an error " Line 6): The value of attribute "value" associated with an element type "variable" must not contain the '<' character." code: <query> <text> let $message := '<Id>CTN53</Id>' return insert nodes $message as last into doc("calastone/calastone.xml") </text> <variable name='message' value='<Id>CTN53</ID>'/> </query> the same code without '<' adds the text correctly. how to solve this problem? Note that this is a question I posted on Stackoverflow, Link<https://stackoverflow.com/questions/60456387/passing-in-xquery-with-basex-p…>. Christian Grun suggested using < and > for attributes and CDATA for text nodes. After applying that solution, the xml stored is in this form <Id>CTN53</Id> This is not what I'm looking for. Is there any other more convenient solutions to store XML messages with Rest APIs? I know PUT method works fine but it overwrites the content of the document. Thank you. P Respectons ensemble l'environnement. N'imprimez ce message que si n?cessaire. Let's respect the environment together. Only print this message if necessary.

Use of function-lookup in REST-XQ environment
by Mauro Mugnaini 04 May '20

04 May '20

Hi all, In order to have a "dynamic backend” implementation to REST-XQ invocations we used the fn:function-lookup() function but we are experiencing a strange behavior if the target looked-up function is an updating function that for example adds a resource to a database. Putting the provided files in the webapp folder of a fresh new BaseX latest (9.3.2) downloaded instance (adding "MIXUPDATES = true” setting in the .basex and with a database named DB already created inside) and invoking the REST function that calls directly the backend function with [1] the resource is correctly created on the database, by invoking the REST function that performs the dynamic lookup by using the fn:function-lookup() with [2] it completes without errors but the resource is not added to the DB. In our implementation the implementation modules are stored in the repo but the same behavior can be reproduced with “direct” function call as per my example. Is there any limitation in the looked-up function related to updating databases? Regards, Mauro [1] http:send-request( <http:request method="POST"> <http:body media-type="application/xml"/> </http:request>, "http://localhost:8984/store", <joe/> ) [2] http:send-request( <http:request method="POST"> <http:body media-type="application/xml"/> </http:request>, "http://localhost:8984/dyn-store", <joe/> )

BaseXClient command line run query requiring admin permissions?
by DYER Chris 04 May '20

04 May '20

I am trying to run some xquery scripts via the basexclient command line after logging in as a user with create permissions, but getting an error that admin permissions are required. basexclient connect to server using db_creator (with CREATE permissions) OPEN MyDatabase RUN test.xq → admin permission needed. Contents of test.xq : //database_info/version If I login as admin user, this sequence works fine. If I run this command via the rest interface in a browser and log in as db_creator, this also works. ( localhost:8984/rest/MyDatabase/?run=test.xq) If I run this command via the rest interface in a browser and log in a guest (permissions NONE) it says read permissions required (expected). Is there some limitation on running xq scripts from the command line client that requires admin permissions? Or am I missing some steps somewhere? Cheers, Chris

Unconfirmed bug: NPE using cached transformer
by Andrew Sales 29 Apr '20

29 Apr '20

Hello, I'd like to run a transform on multiple documents using a cached transformer, accumulating any errors that occur. This minimal example - for $doc in (<a/>,<b/>, <c/>) return try{ xslt:transform( $doc, <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='2.0'> <xsl:template match='/'><xsl:sequence select='error()'/></xsl:template> </xsl:transform>, map{}, map{'cache':'true'} ) } catch * {$err:description} - results in: Error in xsl:sequence/@select on line 1 column 135 of [...]: FOER0000: Error signalled by application call on error()Improper use?

Again, this works as expected if the transformer is not cached.
