Re^5: Regular Expression Translation Help!

[kennethk]

I'm having some trouble understanding the question here, so I will list off some possible inputs and what the output from the conditional operator would be.

• USA111 => 111
• BRA111 => 111
• BRA2#$ => 2#$
• ABC111 => ABC111
• USAabcXY => abc
• usa111xy => usa111xy

In cases where the string changes, the regular expression matched and the result is what was stored in $2. In cases where the string didn't change, the regular expression did not match.

and if i'm reading the regex context correctly, if there's no match at all, then the string sent for matching is returned intact without changes.
my personal preference would be for a code block that is a bit clearer, as combining the search & replace regex and the trinary conditional operator makes it a bit confusing.
