Re: Regular expression

I presume that your brackets cannot be nested? Because in your example strong, all the dollars are between brackets. (Note also that as is, we cannot deduce there are dollar signs in $line, as $10 and $s are two interpolated variables. But let's assume there's a lone q before the first double quote).

Assume that the above is true, and that all brackets are balanced, I'd write something like:

{
    no warnings 'uninitialized';
    $line =~ s/(<[^>]*>|\$[0-9])|\$/$1/g;
}

Alternatively, keep the warning, replace the replacement with $1 || "" and use /e to eval the replacement.

Re:Because in your example strong [sic], all the dollars are between brackets. I don't see any square brackets in his post, and the string is not inside the angle brackets that form the tags.	[reply]

I presumed he meant the `<` and `>` characters when he mentioned "square brackets" - otherwise the example doesn't make much sense. And considering the string starts with `<` and ends with `>`, the "between brackets" condition was ambigious. I just pointed out which meaning I was going to assume. It seems that is the same meaning as you assigned to it.	[reply] [d/l] [select]
