Again we need clarification.  Are you trying to match a decimal value i.e.
[0..9] or are you trying to match the literal string "\d"?

If you are tyring to match the literal string then you want to look for
"\\d" (you MUST escape the backslash hence the double backslash).  If you
are trying to find a decimal character they try =~ /\d/
