Re: Problem with repeating characters in regex

Hi I am trying to capture only the first occurence of a charcter
followed by any word ie: in this sample text

!this is a first level heading
!!this is a 2nd level heading

I only want to find the first item and not the second

current code

$line=~s/\!(^\![A-Z][a-z].+)/$1/gc;

it either doesnt capture any ! or takes out the first ! when there is a double

any ideas

Hi Mike. I'm confused as to what you're trying to do, as your regex
doesn't make sense and is a subtitution rather than a pattern match. My
best guess is that you want to elevate all second-level headings to first-
level ones? Maybe something like

$line =~ s/^!(![a-z].+)/$1/gi;

does what you need.
