Re:  Why is the variable and regex slow in saxon and fa
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?

     <xsl:variable name="BraketedTextRemoved"

I'm just trying to remove content with brackets ( dfd234**#*$#*$#fdfd )

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

Any Ideas?
