Re: Regular Expression help

Thanks Jack. I looked through the code again this morning with fresh eyes, and found the problem to be with the variable I was testing against instead of with the pattern. I was testing against $temp when I sould have been using $temp[$i]. If you hear about some guy in the news tonight who spent his whole work day beating his head against his desk while muttering, "stupid, stupid", that will be me. :) Jack Dempsey wrote:

hey john, just tried this in php and perl, and it seems to give the results you want: <? $bad = "# ARIN WHOIS data and confirm the accuracy of the information provided"; $bad1 = "Resource Type|Resource Name|Resource Handle|Parent Resource"; $good = "A|IANA-RSVD2|AS64512||64512|65535|IANA|Internet Assigned Numbers"; $good1 = "V4|RESERVED-1|NET-0-0-0-0-1||0.0.0.0|0.255.255.255|IANA|Internet"; $pattern = "/^[a-zA-Z0-9]+\|/"; $res = preg_match($pattern, $good1, $matches); if($res){

        print "match<p>";
        print_r($matches);

} else {

        print "no match";

} ?> don't know if the _ is needed as well though... jack
