Dear Group,
Suppose I want a regular expression that matches both "Sent from my iPhone" and
"Sent from my iPod". How do I write such an expression--is the problem,
"Sent from my iPod"
"Sent from my iPhone"
which can be written as,
re.compile("Sent from my (iPhone|iPod)")
now if I want to slightly to extend it as,
"Taken from my iPod"
"Taken from my iPhone"
I am looking how can I use or in the beginning pattern?
and the third phase if the intermediate phrase,
"from my" if also differs or changes.
In a nutshell I want to extract a particular group of phrases,
where, the beginning and end pattern may alter like,
(i) either from beginning Pattern B1 to end Pattern E1,
(ii) or from beginning Pattern B1 to end Pattern E2,
(iii) or from beginning Pattern B2 to end Pattern E2,
.....
Regards,
Subhabrata.
