I simply want to go through and find every numerical value in a single, or batch of, CSS files and multiple times two, then save.
Any suggestions for the easiest way to do this?

2I don't have a solution to your problem, but to avoid these issues in the future, you can look at using extended stylesheet langues like SASS or LESS.Casey Yee– Casey Yee2011-11-08 18:48:44 +00:00Commented Nov 8, 2011 at 18:48

That's a really bizarre question. I guess you can just read a token, check if it's a number and multiply it by two, and write to a file.Xavier Ho– Xavier Ho2011-11-09 06:19:42 +00:00Commented Nov 9, 2011 at 6:19

Using regular expressions could solve your problem. For example, in python you could do the following:
import re
input = "#content {width:100px;height:20.5%;font-size:150.25%;margin-left:-20px;padding:2 0 -20 14.33333;}"
regex = re.compile("-?[.0-9]+")
scaled_numbers = [float(n)*2 for n in re.findall(regex, input)]
split_text = re.split(regex, input)
output = ''
for i in range(len(scaled_numbers)):
output += "%s%.2f" % (split_text[i], scaled_numbers[i])
output += split_text[-1]
This code could be reduced in length, but I've deliberately left it less compact for readability. One flaw with it is that it contracts floats to only 2 decimal places, but that can be easily changed if you really need extended decimals (change the number in "%s%.2f" to the desired number of places).
Note also that this code could change the names of CSS selectors (for example, #footer-2 would become #footer-4.00). If you wanted to avoid that, you'll need to adjust the code to ignore text outside of {...}.
