Remplacer tout sauf une partie
My problem is simple:
I want to filter a text except some part of it. I can match easily the part I don’t want to be filtered. For example
I searched a better way to do that, but the best I can do is using
def allExceptCode( f, content ) # Beware the behaviour will change if you add # parenthesis (groups) to the regexp! regexp=/<code[^>]*>.*?<\/code>|<pre[^>]*>.*?<\/pre>/m tmp="" mem= content.scan(regexp).each do |c| mem <<= c end i=0 content.split(regexp).each do |x| tmp <<= send(f,x) if not mem[i].nil? tmp <<= mem[i] i+=1 end end tmp end
An usage is:
A better syntax would be:
I would expect the split make a search on a regular expression and then give the matched expression into the
$& variable. But it is not the case.
If someone know a nicer way to do that I will be happy to know how.
