is_exist_by_xpath

is_exist_by_xpath($xpath); - this function is used to check the presence of an element on the page, finding it by the specified xpath. (Available from version 6.0.47)

The input function accepts parameters:

  • $xpath – the xpath of the element in the DOM model.

    After the function returns the result of their work in the script (the return value type is boolean):
  • true – executed successfully
  • false to find this element failed (e.g. no items that meet the specified criteria or not this frame)

    PHP example:

    <?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();
    ?>

    Python example:

    # Additional paths
    import sys
    sys.path.insert(0, '../../../Templates PY/')
     
    xhe_host = "127.0.0.1:7031"
    from xweb_human_emulator import *
     
    # Start
    echo("<hr> <font color = blue> common.xxxxxxxxx </font> <hr>")
     
    # 1
    echo("1.Let's go to the polygon:")
    echo(browser.navigate("http://www.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]"), "
    ")
     
    # 3
    echo("3.Check for non-existent element in frame zero:")
    if not anchor.is_exist_by_xpath("/bb"):
          echo("element not exist")
     
    # end
    echo("<hr> <br>")
     
    # Quit
