c# - string replace with exception on certain strings -


i have line of code i'm using prepare css file:

theminifiedcss = theminifiedcss.replace("white", "#fff");

the problem in css, have declaration:

.someclass{white-space:pre-wrap;}

how change .replace statement replace white #fff leave white-space alone?

thanks.

note, know can add theminifiedcss = theminifiedcss.replace("#fff-space", "white-space"); i'm looking cleaner.

people keep trying write rules things appear before or after "white", when think what's desired "white" own token , not part of selector.

regex.replace(theminifiedcss, @"(?<![-_a-za-z0-9#.])white(?![-_a-za-z0-9])", @"#fff");

a more complete rule implement entire rule identifier tokens in css, think 1 covers keywords.

here's trickier test case has been posted far:

.white> td { color: white;box-shadow: 0px 0px 3px white, inset 0px 0px 5px black; white-space:pre-wrap; } body { background: url('test.png'),white; }

even trickier, , not handled example, filenames.

body {   background-color:white;   background-image:url('almost white, not really.png'); }

to right, need full css parser.
