search and replace avancé

## trop simple, sans doute, mais voici en tout cas:

texte = '''
tralalala nil nisi divinum stabile est
\url{adresse_web_0}
the naming of cats is a difficult matter
\url{adresse_web_1}
i shall wear the bottoms of my trousers rolled
\url{adresse_web_2}
headpiece filled with straw, alas
'''

def remplaceur(x):
i = x.index('{')
j = x.index('}')
adresse_web = x[i+1:j]
return '<A HREF = "' + adresse_web + '">' + adresse_web + '</A>'

def f(t):
from string import replace
i = t.index('\\url')
j = i + t[i:].index('}')
x = t[i:j+1]
return replace(t,x,remplaceur(x))

def g(t):
while True:
try: t = f(t)
except: break
return t

print texte
print g(texte)
