Re: What's wrong with my regular expression?

If you want to match more than one occurrence of the same pattern, you must use preg_match_all with Perl syntax. The matches will be returned as an array of arrays (that is, an array that contains the result of a normal ereg call for each match found): $line = '<a href="http://www.yahoo.com">http://www.yahoo.com</a>'; $line .= 'X<a href=http:/www.php.net>www.php.net</a>'; if (preg_match_all("/(<( )*[Aa]( )*[Hh][Rr][Ee][Ff]( )*=( )*[\"'][^<>\"']*[\"']( )*>[^<>]*<( )*\/( )*a( )*>)/",$line,$matches)) { print ($matches[0][0]); // Returns the first match print ($matches[1][0]); // Returns the second match } Also, your regular expression didn't cover all the possibility (eg: spaces between href and =. I might have overdone it with mine but, hey, I've got a turkey to cook and it's already late ;-) Cheers, Marco On Mon, 2002-10-14 at 07:40, Ns_Andy wrote: > $line = '<a > href="http://www.yahoo.com">http://www.yahoo.com</a>'; > if (eregi("<a[ ]+(.*[ > ]+)?href=([\"'])?([^<>\"'])+([\"'])?>[^<>]+<\/a[ > ]*>",$line,$matches)) { > print (htmlspecialchars($matches[0])); > } > > it works fine, > however if > $line .= 'X<a > href=http:/www.php.net>www.php.net</a>'; > is added before eregi, > it doesn't,what's wrong with my code? > -- > Regards, > > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php >
