[basex-talk] BaseX supporting 'lookahead' and 'lookbehind' regular expressions

Greetings All, I am trying to use 'lookahead' and 'lookbehind' regular expressions with BaseX With no success. )more about lookahead/behind can be found at: http://www.regular-expressions.info/lookaround.html Example expression: q(?=u) I fear that BaseX does not support these options Does BaseX support these options? Is there any alternative syntax for it? R
