Re^2: array manipulation with string

Hmmm ,

The OP would like the existing IP address prefixed with i.e. not replaced by, the string 'IP_', viz:

s/^/IP_/ for values %{ $newHosts->{ server } };
[download]

$_ = q/IP_/ . $_ for values %{ $newHosts->{ server } };
[download]

A user level that continues to overstate my experience :-))

jwkrahn's code is not doing a replacement because his pattern is inside a zero-width positive look-ahead assertion, i.e. it is in effect doing an insertion at a point in the string that is followed by the pattern because the item being substituted is zero-width. Cheers, JohnGG	[reply]
