Can you please advise on how to return a string between 2 specific characters?



I want to return : 1364871116_438861511, which is between "period_1_" AND ".ssa"

Use this regex:


For example, in Perl you would extract it like this:

my ($substr) = ($string =~ /period_1_(.*)\.ssa/);

For Python, use this code:

m = re.match(r"period_1_(.*)\.ssa", my_long_string)

Last print will print string you are looking for (if there is a match).

Thanks mvp, but when I tested it using this RegEx tester: It returns "period_1_1364871116_438861511.ssa" and not "1364871116_438861511" – Paul M Apr 2 '13 at 6:47
Which language you are using? I have tried my Perl code, and it does work. For regex tests online, I prefer, this link proves that it works for Java for example (see group(1)) – mvp Apr 2 '13 at 6:56
Python and/or .JS, I think. I'm using this in XBMC, if you're familiar with it. I'm not a programmer, so I just need a reg expression that returns just "1364871116_438861511". Thanks for your help bro! – Paul M Apr 2 '13 at 7:04
Use this link and click on Python test: it shows that you should use findAll() or group(1) methods to get what you want. – mvp Apr 2 '13 at 7:07
Edited answer to add Python example – mvp Apr 2 '13 at 7:12
