Oh, I have never seen that. In that case, why
did Roman's first example not work well for
HTML tags?
'<.*?>'
Also, how does the engine decide whether I am adjusting
the greed of the previous operator, or just asking
for another possible character?
Suppose I want:
"x*?" to match "xxxxxxxO"
If the '?' means non greedy, then I should get 'x' back.
If the '?' means optional character then I should get
the full string back.
Checking in python:
######################################
import re
s = 'xxxxxxx0'
m = re.search("x*", s)
print "First way", m.group(0)
m = re.search("x*?", s)
print "Second way", m.group(0)
#####################################
First way xxxxxxx
Second way
So now I'm really confused. It didn't do a non-greedy
'x' match, nor did it allow the '?' to match the '0'.
