Re: [basex-talk] optimize BaseX performance

how to print QueryInfo through Java API ?

The -V flag or the QUERYINFO option are alternatives; please find more information in the documentation.

"transaction/* except (/transaction/traInfo)"

You could try to rewrite this to... transaction/* except traInfo ...or... let $traInfo := /transaction/traInfo return transaction/* except $traInfo ...or... transaction/*[name() ne 'traInfo']
