Hi guys,

First of all, lemme show you some example values I need to match: 
[url]http://www.test.com[/url]
[img]http://www.site.com/image.jpg[/img]
[url http://www.test.com]name of link[/url]
[citation]some quote here[/quote]

[download]
Now, I have this regex: 

    while ($_[0] =~ /\[(\/?)(lien|url|citation|img).+?\]/sg) { 
        print "GOT: $1 and $2 \n";
    }

[download]
..which is meant to capture the / (if it exists, after the [, and assign to $1), and then also capture to tag name itself to $2)

However, it doesn't seem to work (it only picks up the ones without the / in the tag)

If I change the regex to remove .+? , so we have: 

    while ($_[0] =~ /\[\/?(lien|url|citation|img)\]/sg) { 
        print "BLA: $1 \n";
    }

[download]
..it works, but obviously doesn't pick up stuff like:

[url http://www.test.com]some text[/url]

Anyone got any suggestions?

UPDATE: I think I've worked it out - I needed .*? instead of .+? , cos .*? can mean 0 or more results, whereas .+? means "at least 1")

TIA

Andy
