Regex to match css key value string

Question

I am using regex to match css values.

Input string to match

 font-size:25px;font-family:georgian;content:"' unicode given in pseudo &#169; '";

Regex I am using to match

/.*\bcontent:(\s*[^;]*)/

I am using $1 to get the actual string output of regex

Expected output is "' unicode given in pseudo &#169 '"**

But actual is "' unicode given in pseudo &#169

Because regex finds ; in the content value so it breaks there. So how can i fix this bug. Ideally regex should look for the last ; which is not inside the double/single quotes. Because my input string will always have ; after each property value ends.

Thanks

Try /.*\bcontent:\s*(.*);/ to match up to the last ; char on a line. Or just /\bcontent:\s*"([^"]*)";/ (demo) — Wiktor Stribiżew

Simplify it: Take the piece of text within quotes:

/.*\bcontent:(\"[^\"]*\")/

If one wants to simplify the pattern, one would omit .* in the pattern. As in my comment, it is enough to use /\bcontent:("[^"]*")/ (I just placed the capturing group inside the quotes to exclude them from the match).

its failing for this case content:"'@@@@@@@@@@@@@ '","'@@@@@@@@@@@@@&&&&&&&&&&&&&&&&&&&&&&&&@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@'","'@@@@@@@@@@@@@&&&&&&&&&&&&&&&&&&&&&&&&@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@'";

@WiktorStribiżew This works but not for all the cases.Ideally regex should look for the last ; which is not inside the double/single quotes. Because my input string will always have ; after each property value ends.

@Pavan, of course it fails, there's no 'content' in your string.

@PavanTiwari You cannot get an undefined number of quoted substrings until the first non-quoted semicolon with a regular expression. You need to code an specific parser for that matter.
