Retrieving text between 2 strings/chars...

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I'm looking for an RE which will do something like this:

"hello there <here I am> today is sunny"

I want to grab everything between the characters < and > . It should return the string

"here i am"

thanks

Try: `my $TestString = "hello there <here I am> today is sunny"; my @Matches = ($TestString =~ m\|<(.+?)>\|ogs);` [download] This initializes `@Matches` with a list of all text strings between an initial < and the first > following it, possibly including later < characters. (In particular, "<<WonderText>>" would have the single match "<WonderText".) As for the modifiers (a quick review; cf. the perl documentation for a full explanation) g: global matching o: one-shot (the regex is defined at compile time) s: arbitary string (don't break just because \n is in the string) Another modifier that is very practical is: i: case-insensitive I generally reach for the documentation if I need anything more complicated than the above.
