Hi,

I'm currently converting my project to use BaseX instead of Saxon. One thing you can do in Saxon is provide a flag (an exclamation mark) to your regular expression to tell the matches function to use the Java regular expression processor, rather than the rather cut down expressions available in the XQuery spec.

Is there anything similar in BaseX? 

If not what do you recommend to define a Java regular expression based function for XQuery?

Thanks in advance,

Gary
