iamX Posted March 13, 2006 Share Posted March 13, 2006 Hay there, Hope someone can help me with the following. I'm creating a script that indexes links on pages to create easy sitemaps.I have already stripped tags except <a> and I use preg_match_all to collect all the links with the following:$matched = preg_match_all("{m=more&id=(.*?)>(.*?)</a>}", $txtonly, $match);but now the problem.:Some links have a graphic before them with the same m=more&id=###> link.But since the <img> tags has been stripped it's empty so when rebuild it results in:<a href=sitemap.php?m=more&id=###></a> and an <a href=sitemap.php?m=more&id=###>Link name</a>I tried replacing the second (.*?) in (.+?) but then the result is:<a href=sitemap.php?m=more&id=###></a><a href=sitemap.php?m=more&id=###>Link name</a>(double result)No result when matching for [a-zA-Z0-9]Am I missing something or approaching this the wrong way?

wickning1 Posted March 13, 2006 Share Posted March 13, 2006 $matched = preg_match_all("{m=more&id=(.*?)>([^<]+?)</a>}", $txtonly, $match);Try that.

iamX Posted March 13, 2006 Author Share Posted March 13, 2006 Aah I found it! The greedy first (.*?) was the troublemaker. My code came out like this:$matched = preg_match_all("{m=more&id=([A-Z0-9]+?)>([^<]+?)</a>}", $txtonly, $match);No double Href's anymore :) Quote Link to comment https://forums.phpfreaks.com/topic/4827-trouble-with-regular-expresspions/#findComment-17067 Share on other sites More sharing options...
