Hi - I have a script to retrieve a line of data from a webpage. The line is either:
<p>and-the-info-here

or, if there is no info just:
<p>
Code:

to send this into the room, the script after the socket stuff is:

    if {[string match "*<p>CENTRAL*" $line]} {
   regexp {<p>CENTRAL(.*).</p><br>} $line - central
    putserv "PRIVMSG $channel :$central"
    } else {
    putserv "PRIVMSG $channel :No Info Available"
  }
 }
}

however, it is sending both lines to the room even if there is data. I've tried putting returns in after, but then it only does the second line.

Thanks for any help?

Did you try common sense? Wink
Code:
 if {[string match "*<p>CENTRAL*" $line]} {
  if {[regexp {<p>CENTRAL(.*).</p>} $line - central] && [string length $central] >= 1} {
    putserv "PRIVMSG $channel :$central"
  } else {
    putserv "PRIVMSG $channel :No Info Available"
  }
}


(I added the string length check to see if anything is actually in the variable)
