fixed the issue. Will look into that further I start by saying I am very new on shell script so please don't shoot me !! :) , This works for me:
code :
sed 's#/\([^/]*\)/#\1#' file
$ sed 's#/\([^/]*\)/#\1#' file
1   :    /
2   :    string-1
4   :    string-2
5   :    string-3
sed -r 's#/([^/]+)/#\1#' file

like below fixes the issue I think you'll need to capture the stuff that comes before and after the display attribute.
code :
(<customer.*?)(display="(?:yes|no)")(.*?>) 
Regex.Replace(inputString, @"(<customer.*?)(display=""(?:yes|no)"")(.*?>)", m => String.Format("{0}{1}{2}", m.Groups[1], /* replacement string based on m.Groups[2] */, m.Groups[3]));

I hope this helps . As mentioned in the documentation:
code :
let re = Regex::new(r"(?P<first>\w+)\s+(?P<second>\w+)").unwrap();
let result = re.replace("deep fried", "${first}_$second");
assert_eq!(result, "deep_fried");

it should still fix some issue The $1 backreference will only work directly in the replace function, not in parameters passed to other functions. Luckily, String.replace can use a function as a replacement instead of just a string; in that case, the matched substrings are passed to the callback as parameters, and then whatever the function returns will be used as a replacement.
For a global replacement, the callback is called once for each match. The first argument is the full match, the second is the first captured group, the third is the second captured group, etc.
code :
toClean.replace(/([&"'<>](?!quot;|lt;|gt;|apos;|amp;))/g, (match, sub1) => _.toUpper(sub1));

I wish this help you I have a CSS file which includes a set of rules wrapped in a @critical rule containing critical styles whose content I want to extract for inlining: , If perl is your option, would you please try:
code :
perl -0777 -i.bak -pe 's,\@critical[^{]*{\s*((.|\s)*)[^}]*},$1,g' style.css
.foo {
        ...
    }

    @media bar {
        ...
    }
