RE: [PHP] Regular Expression help

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 > -----Original Message----- > From: John Nichel [mailto:jnichel@by-tor.com] > Sent: Tuesday, April 15, 2003 5:37 PM > To: php-general@lists.php.net > Subject: [PHP] Regular Expression help > > > I am trying to match a line which starts with an alpha-numeric "word" > followed by a pipe ( | ), however my regex's seem to be a bit off > > When I use the following... > > ^[A-Za-z_0-9]+\| > > It matches none of the lines.
