I don't know - they are both, I think, using the Java regular expression engine underneath. It may be a function of how you are measuring it. It could be that the cost is dominated not by the cost of evaluating the regex, but by the cost of checking that it conforms to the XPath rules. Did you run a Java profile to determine where the time is being spent?

HI,
I'm unable to figure out why this regex is so very time consuming such
that it does not end in oxygen but works quickly in regex buddy on the
same content.
     <xsl:variable name="BraketedTextRemoved"
        select="replace($title,'$[^$]*\)','')"/>
I'm just trying to remove content with brackets ( dfd234**#*$#*$#fdfd )

Running on vendor="SAXON 9.2.0.6 from Saxonica" version="2.0"

Any Ideas?
Thanks
Alex
