    <?php $xhe_host = "127.0.0.1:7013";
 
//connect the object to control the emulator, if not already connected
if(!isset($path))
   $path = "../../../Templates/xweb_human_emulator.php";
require($path);
 
//Start
echo "<hr> <font color = blue> anchor->".basename(__FILE__)."</font> <hr>";
 
//1
echo "1.Let's go to the polygon:";
echo $browser->navigate("http://humanemulator.net/poligon/anchor.html")."<br>";
 
//2
echo "2.Check if there is an element with the given xpath:";
echo $anchor->is_exist_by_xpath("/html/body/a [1]")." n";
 
//3
echo "3.Check for a nonexistent element:";
if($anchor->is_exist_by_xpath("\ bbbb") === false)
      echo "element not exist";
 
//end
echo "<hr> <br>";
 
//Quit
$app->quit();
?>

# 2
echo("2.Check if there is an element with the given xpath:")
echo(anchor.is_exist_by_xpath("/html/body/a [1]"), "

# 3
echo("3.Check for non-existent element in frame zero:")
if not anchor.is_exist_by_xpath("/bb"):
