[Brisbane-pm] Still Struggling With Regex Syntax

[Martin Jacobs]

Hi folks,

I still don't get it (quite).

The story so far...

I have split my rainfall record, and the right-most scalar is $rain.

I now want to make sure that $rain holds a numeric value, without any  
whitespace, newlines or other nasties.

If I try

$rain = ($rain =~ m|\d+\.?\d*|);

It returns 1, which, presumably, is the number of times it gets a match.

What's the right syntax for saying 'make $rain contain the numeric  
values in $rain"?


Regards,
Martin
