Hi all,

I am reading a template file line by line, substituting certain keywords with variables as I go and writing to an output file.

The keywords are identified in the template as <:KEYWORD:N:>, where 'N' is an optional multiplier that should be applied to the value of the variable associated with the KEYWORD.

Without the 'N' multiplier, this is easy; I simply do: 
$line =~ s/<:KEYWORD:>/$value/;

However, I'm scratching my head over the best way to handle the multiplier.
I want to do something like: 
$line =~ s/<:KEYWORD:(.*):>/$value * $1/;

[download]
where the replacement is evaluated on the fly.

How do I do this?

Thanks in advance,
--Darren
