Python CSS Parser

Question

I am experimenting with CSS files in Python to assist colour blind people. I need to get inside every selector block and change the 'background:' and 'color:'. I tried using CSS parsers like tinycss but they are not concentrating on getting selectors.

Example input:

body {background:#fff; color:#ccc}

And output:

body {background:#000; color:#aaa}

Answer 1

try this:

http://cthedot.de/cssutils/

parser = CSSParser()
# optionally
parser.setFetcher(fetcher)
sheet = parser.parseFile('test1.css', 'ascii')
print sheet.cssText

it's pretty simple to use in css processing.

to work with selectors you could use cssutils.css.SelectorList and cssutils.css.Selector
