How can I parse out numbers from a topic name. eg. Item0002

Is there any easy way to get a number from a topic name. For example get "0002" out of a topic named Item0002? .

Thanks. The following example taken from that link works great:

%SEARCH{
  "%TOPIC%"
  scope="topic"
  nonoise="on"
  format="$percntCALC{$REPLACE($topic,1,$EVAL($LENGTH($topic)-4))}$percnt"
}%

It would still be super awesome if we could do something like:

%TRIM{%TOPIC%, 0, 4}%

parameters are: {string to trim, beginning position, end position}

Thanks guys. IsmaelAntadillas
