Preg Match

[ajicles]

I need help again with preg match and trying to grab text between two xml tags. And it doesn't return anything back to be I tried adding /s to my pattern for the multi line thing. I am new and getting better at what the patterns mean and stuff.

 

Thanks

Code:

 

$server = "68.168.98.191";
$port = "13511";
$password = "********";

$fp = fsockopen("$server", $port, $errno, $errstr, 30);
      fputs($fp, "GET /admin.cgi?pass=".$password."&mode=viewxml HTTP/1.0\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)\r\n\r\n");
      while (!feof($fp)) {
          $content = fgets($fp);
}

//echo $content;

      function getTextBetweenTags($string, $tagname)
      {
      $pattern = "/<songtitle>(.*?)<\/songtitle>/s";
      preg_match($pattern, $content, $matches);
      return $matches[1];
      }

 

Echo Content Returns:

Your regular expression is case-sensitive meaning that the lowercase letters will not match the uppercase letters which are present in the XML.  Either change the regex to have uppercase SONGTITLE or use the case-insensitive pattern modifier (/.../si) to match your pattern case-insensitively.

 

Also, why are you using antiquated methods of a) retrieving the XML and b) accessing the SONGTITLE?

[ajicles]

Its for Shoutcast radio and the XML and setting are behind a password protected area.

Yay, it works fantasic.  Ill I had to is add the i in the pattern and remove the function because it wasn't working, because I tried to echo hello in it and it didn't return anything lol.

 

$server = "68.168.98.191";
$port = "13511";
$password = "";

$fp = fsockopen("$server", $port, $errno, $errstr, 30);
      fputs($fp, "GET /admin.cgi?pass=".$password."&mode=viewxml HTTP/1.0\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)\r\n\r\n");
      while (!feof($fp)) {
          $content = fgets($fp);
}
      $pattern = "/<SONGTITLE>(.*?)<\/SONGTITLE>/si";
      preg_match($pattern, $content, $matches);
      echo $matches[1];

I don't have a Shoutcast server to try this on but the following should, theoretically, also work*. Or at least show you an alternative approach should you want to use it.

 

echo simplexml_load_file("http://68.168.98.191:13511/admin.cgi?pass=&mode=viewxml")->SONGTITLE;

 

 

* Assuming of course that the SimpleXML extension is enabled and it can talk to that URL.

[ajicles]

Well the only thing is it is a remote server and the xml is always changing with the new data. The .htaccess or something isn't allow to access it because it is a server talking to a server not a server talking to a client. So it disallows it to access it.

You could set the user_agent INI option, or provide a stream context for SimpleXML to use. The first just dictates the default user agent to send along, the second allows far more fine-grained control of the request.

Its a remote server and I can't edit anything on it. I am a noob at php lol.

The changes that I mentioned are for your script, not the remote server.
