it helps some times You say "I know its very expensive as I am doing the matching for a particular string several times." That suggests to me that you are running each RE several times. In that case, you are making a mistake that can be resolved without writing a more complex RE.
code :
re1_matches = re.findall(re1, text)
re2_matches = re.findall(re2, text)
>>> re1 = r'(\d{1,3}[a-zA-Z]?/\d{1,3}[a-zA-Z]?)'
>>> re2 = r'(\babc\b)'
>>> re.findall(re1, text)
['100/64h', '120h/90', '200/100', '100h/100f']
>>> re.findall(re2, text)
['abc', 'abc']
>>> re1_matches = re.findall(re1, text)
>>> re2_matches = re.findall(re2, text)
>>> rex_nomatch = re.findall('conglomeration_of_sandwiches', text)
>>> not re1_matches and re2_matches
False
>>> not rex_nomatch and re1_matches
['100/64h', '120h/90', '200/100', '100h/100f']
>>> not rex_nomatch and re2_matches
['abc', 'abc']
>>> re1_matches and re2_matches
['abc', 'abc']
>>> re1_matches and re2_matches and re1_matches + re2_matches
['100/64h', '120h/90', '200/100', '100h/100f', 'abc', 'abc']

Does that help I feel like I can learn a lot by seeing these two regular expressions as one. Mainly selecting the space in between > and < while not selecting the > and < themselves, so I can replace it with "" rather than "><". Is there a way that these could be merged without selecting that space?
code :
$html = preg_replace('/[\n\r]+|(?<=>)\s+(?=<)/',"",$html);

seems to work fine Yes, Visual Studio has its own strange regex dialect, for details see here on msdn
The problem in your expression is that it does not know the predefined classes \w and \s
code :
prm[a-zA-Z0-9]+:b=:b[a-zA-Z0-9]+

may help you . You can just use an Pipe (|) in between your multiple Regex, to match all of them : -
code :
    String s = "name lastname (username) <mail@mail.something.dk>; name lastname
            (username) <mail@mail.something.dk>; name lastname 
            (username) <mail@mail.something.dk>;";

    // Matches (?<=\\()[^\\)]+  or  ((?<=<)[^>]+)
    Pattern pattern = Pattern.compile("(?<=\\()[^\\)]+|((?<=<)[^>]+)");
    Matcher matcher = pattern.matcher(s);

    while (matcher.find()) {
        System.out.println(matcher.group());
    }
username
mail@mail.something.dk
username
mail@mail.something.dk
username
mail@mail.something.dk
    String s = "name lastname (username) ; 
                name lastname (username) <mail@mail.something.dk>; 
                name lastname (username) <mail@mail.something.dk>;";

    String [] strArr = s.split(";");

    for (String str: strArr) {

        Pattern pattern = Pattern.compile("\\(([^\\)]+)(?:\\))\\s(?:\\<)((?<=<)[^>]+)");
        Matcher matcher = pattern.matcher(str);

        while (matcher.find()) {
            System.out.print(matcher.group(1) + " " + matcher.group(2));
        }
        System.out.println();
    }
username mail@mail.something.dk
username mail@mail.something.dk // Only the last two have both username and email

hop of those help? I need to extract a string that is enclosed by both parentheses and single quotes. Currently, I am using two regex pattern to do the job. With the first regex I retrieve a string from parentheses while the string still contains single quotes, and with the second regex I can strip that single quotes from it. Now, I would like to do this job in a single step. For the past one hour and so I have been experimenting with some patterns without any viable results; may be its due to my limited regex knowledge. So, any feedback you offer to me will be very helpful. I also welcome any solutions apart from regular expressions. , You can use this single regex:
code :
preg_match("#\('([^']+)#", $string, $matches);
echo $matches[1];
//=> minute stroller workout
