Graal Forums - Detect HTML

I made this quickly for my message system that used GUIs.

I'll probably eventually make it simply remove the HTML, but for now it's a way to tell if they inputted HTML.

An example is if you have a GUI message system, and someone massed <img src="block.png"> for example. You could disable HTML, but then if you needed colors, etc, you couldn't use them.

The way I used it was this:

PHP Code:


		
			
if ( player.chat.starts( ":mass" ) )
  {
    temp.txt = player.chat.substring( 5 ).trim();
    temp.h = removeHTML( temp.txt );
    triggerserver( "gui", name, "massMessage", temp.h );
  }

Here is the class.

Script for class functions_removehtml:

PHP Code:


		
			
public function removeHTML( text )
{
  this.html = { "a", "b", "body", "br", "center", "font", "hl", "hr", "i", "ignorelinebreaks", "img", "p", "spam", "ul", "ol", "li", "div" };

  for ( temp.a : this.html )
  {
    temp.n = "<" @ temp.a;
    if ( text.pos( @ temp.n ) > -1 )
    {
      temp.p = ( text.pos( @ temp.n ) );
      text = text.substring( 0, temp.p ) @ text.substring( temp.p + 1 );
    }
    temp.n = "</" @ temp.a;
    if ( text.pos( @ temp.n ) > -1 )
    {
      temp.p = ( text.pos( @ temp.n ) );
      text = text.substring( 0, temp.p ) @ text.substring( temp.p + 1 );
    }
  }
  return text;
}
//#CLIENTSIDE
public function removeHTML( text )
{
  this.html = { "a", "b", "body", "br", "center", "font", "hl", "hr", "i", "ignorelinebreaks", "img", "p", "spam", "ul", "ol", "li", "div" };

  for ( temp.a : this.html )
  {
    temp.n = "<" @ temp.a;
    if ( text.pos( @ temp.n ) > -1 )
    {
      temp.p = ( text.pos( @ temp.n ) );
      text = text.substring( 0, temp.p ) @ text.substring( temp.p + 1 );
    }
    temp.n = "</" @ temp.a;
    if ( text.pos( @ temp.n ) > -1 )
    {
      temp.p = ( text.pos( @ temp.n ) );
      text = text.substring( 0, temp.p ) @ text.substring( temp.p + 1 );
    }
  }
  return text;
}

It's a very simple script, but I figured someone might get some use out of it. When I make it remove HTML, I will update it.

Feel free to leave feedback!
Thanks,
Chris Zakuto

EDIT: Updated it to remove the HTML instead of just giving an error. It removes the < right before it, making it not work. There was also another error that I fixed.
