I have a need to search for numeric portions of strings in my data, do a simple calculation on them, and reinsert the result back into the string forming a new string. I can't seem to get my head around how I would do it.

Specifically, supposing I had a string that looked like this:

<$inData="action/4 request/3 dimension/2">

How would I, say, double the "request" identifier and so that the resulting string is:

"action/4 request/6 dimension/2"

I don't necessarily want to always double values, but I'm just saying this as an example. Once I figure out how to extract the specific numeric piece and reinsert it back into the string, I can handle all the various calcs I need to do.

Thanks in advance

<a name=numbers hit>
<$ret=(2*$hit)>$ret<!--nonewline-->
</a>
<a name=main>
<$inData="action/4 request/3 dimension/2">
<fmtcp sandcall "\digit+" numbers>
In: $inData
Out: <sb>$inData</sb>

</a>

use <capture><sb>$inData</sb></capture><$outData=$ret> to put into a string instead of print.

Thanks! This works great!
