open from url extra

[<php...@li...>]

One more addition to that last code...append a
"@" to the beginning of the
implode call when it is a url to suppress php
warnings...since the xpath
warning will be outputted anyway...

Oh, and if you want to do a socket
connection...check out the code from the
rdf php class...which you can find at
http://www.fase4.com/rdf/

I also put a snippet of the code below....

      if ( $this->_use_proxy == true )
      {
       // we need a raw socket here to connect to
proxy
       $fp =
fsockopen($this->_phost,$this->_pport);

       if (!$fp)
           $this->_throw_exception(
$this->_remote_file." is not available
with proxy" );
       else
        {
          if ( $this->_use_proxy_auth == true )
           fputs($fp, "GET
".$this->_remote_file." HTTP/1.0\r\n\r\n");
          else
           fputs($fp, "GET
".$this->_remote_file."
HTTP/1.0\r\nProxy-Authorization: Basic
".base64_encode("$this->_pname:$this->_ppasswd")
."\r\n\r\n");
        }

       for ( $i = 0; !feof ($fp) ; $i++)
       {
          $usable_data[$i] = "";
          $usable_data[$i] = fgets($fp,4096);

        // strstr did not fit (ask Rasmus why),
so we compare each character
          if ( ($usable_data[$i][0] == "<" ) &&
($usable_data[$i][1] == "?" ) &&
($usable_data[$i][2] == "x" ) &&
($usable_data[$i][3] == "m" ) &&
($usable_data[$i][4] == "l" ) ) {
          $usable_data[0] = $usable_data[$i]; //
save current field
          $i = 1; // just reset array to start
          }

        // there seems to be a "date" after the
<?xml....we just delete this
          if ( ($usable_data[$i][0] == "<" ) &&
($usable_data[$i][1] == "r" ) &&
($usable_data[$i][2] == "d" ) &&
($usable_data[$i][3] == "f" ) &&
($usable_data[$i][4] == ":" ) ) {
          $usable_data[1] = $usable_data[$i]; //
save current field
          $i = 2; // just reset array to start
          }

       }

       fclose($fp);
       return $usable_data;
   }
