OK, that's pretty neat, but I realize now that my example was
unintentionally misleading. The problem is not quite as regular as I made
it out to be.
What if I want to execute different code depending on which expression I
matched? Something along the lines of (pseudocode):
if (m = e1.match(line)):
text1 = m.group(1)
do_complicated_processing (text1)
elif (m = e2.match(line)):
text1 = m.group(1)
text2 = m.group(2)
print text1, text2
elif (m = e3.match(line)):
return
