Regex alone: /\{([^\}]*)\}/g
notice the g at the end - without it the regex would return a scalar with
text1 in it
Regex basically says: find a string that starts with { and ends with } but
does not have any }'s in the middle (avoids greedy matches - if you use .*
instead of [^\}]* you would get everything from the first { to the last })
Regex in action:
#!/usr/bin/perl
my $str = 'this is some {text1}. this is more {text2}. and yet some more
{text3}.';
my @results = $str =~ /\{([^\}]*)\}/g;
# displays text3 (last match found)
print "$1\n";
# displays text1, text2 and text3
foreach $result (@results)
{
print $result."\n";
}

Subject: [brlug-general] noob regex question
Howdy,
I have a bunch of text with multiple tokens in it demarcated by { and }.
Sample text:
this is some {text1}. this is more {text2}. and yet some more {text3}.
blahdeblah.
What would a regular expression to get these tokens out of the text look
like, in a Perl script, say?
Thanks,
John
