[power-pro] Regex expert help needed

[Owen Watson]

I'm a bit out of my depth here with regex in PPro.
At the moment my replace line is here:
textIn[?"([\x7F-\xFF]+)"]="<b>GREMLIN(\\1)</b>"
. . in other words, I'm trying to replace upper-ASCII characters with
an alert message and the original chars. However, I'd like the chars
displayed after GREMLIN to be the hex codes separated by spaces.
ie GREMLIN(FF E7 E8)
Is this possible?
