I'm using baseX in a REST environment and I'm quite stuck trying to run an .xq script with an undefined number of GET variables (could be 1 but could be 10) I'd like to make my xq script generic about that and construct my query independently. Is there a way to achieve that, playing with array or sending differently my variables, or I dunno how ?
here is my API call
http://basex:8984/rest/?run=WEB-INF/data/test.xq&$tag=p&value=sciences&tag2=p&value2=test&tag3=testdzq
here is my text.xq
declare variable $tag external;
declare variable $value external;
declare variable $tag2 external;
declare variable $value2 external;
<documents>
{for $doc in collection("testdb2")
where $doc//*[name() eq $tag]/text()[matches(., $value )]
and $doc//*[name() eq $tag2]/text()[matches(., $value2 )]
return <doc>{$doc//titleStmt/title/text()}</doc>
}
</documents>
Thanks !
found this here (see http-params function) https://www.balisage.net/Proceedings/vol18/print/Murray01/BalisageVol18-Murray01.html
