Help with a regular expression

[rofranco]

Hi,

I'm trying to match a series of terms in a boolean expresion like this:
medicinal AND clinical AND behavoiural

I made this regular expresion, and I cannot understand what am I doing wrong, since it matches the whole sentence, but it only gathers the first and the last terms...

([\S]+)( AND ([\S]+))+

Matches:
Group(0) = medicinal AND clinical AND behavoiural
Group(1) = medicinal
Group(2) = AND behavoiural
Group(3) = behavoiural

Any suggestions ??

Thanks in advance.

Yes. It's "behavioural"

Oh, and welcome here!

Now over to those who haven't forgotten their regexp stuff yet ...

Yes the regexp is correctly interpreting your string. Remember most regexps are greedy by default.

Personally I'd use perl's split /AND/, "stuff AND to AND split" instead, much easier. This is the sort of thing perl is good at.

perl -e 'print split /\s+AND\s+/, "yo AND dude AND hows AND my AND car\n";'
