get_child_by_number

get_child_by_number($number,$include_subchildren=false); - get the interface of the DOM child element with the specified index (available from version 4.6.41)

the input Function accepts parameters:

  • $number – number of the first-level child element (order, index in the list of child elements) (int).
  • $include_subchildren – also search for all child subelements. (available from version 7.0.23)

    After testing, the function returns the result of its work to the script :
  • DOM element interface – an object that allows you to quickly perform any operations with the found element, the return value type XHEInterface

    PHP example:

    <?php $xhe_host = "127.0.0.1:7014";
     
    //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> interface->".basename(__FILE__)."</font> <hr>";
     
    //to make it faster
    $browser->set_wait_params(5,1);
     
    //1
    echo "1.Let's go to the polygon:";
    echo $browser->navigate("http://humanemulator.net/poligon/btn.html")."<br>";
     
    //2
    echo "2.Get tags of all elements in 0 form:";
    $frm0 = $form->get_by_number(0);
    for($i = 0; $i <$frm0->get_child_count(); $i ++)
    echo $frm0->get_child_by_number($i)->get_tag()."";
     
    //3
    echo " n3.Get tags of all elements in 0 form(including subelements):";
    $frm0 = $form->get_by_number(0);
    for($i = 0; $i <$frm0->get_child_count(true); $i ++)
    {
    echo $frm0->get_child_by_number($i, true)->get_tag()."";
    }
     
    //end
    echo "<hr> <br>";
     
    //Quit
    $app->quit();
    ?>

    Python example:

    # Additional paths

    from xweb_human_emulator import *
     
    # Start
    echo("<hr> <font color = blue> interface.xxxxxxxxx </font> <hr>")
     
    # to make it faster
    browser.set_wait_params(5,1)
     
    # 1
    echo("1.Let's go to the polygon:")
    echo(browser.navigate("http://www.humanemulator.net/poligon/anchor.html"), "<br>")
     
    # 2
    echo("2.Get tags of all elements in 0 div:")
    div0 = div.get_by_number(0)
    for i in range(0, div0.get_child_count() - 1):
    echo(div0.get_child_by_number(i) .get_tag(), "")
     
    # end
    echo("<hr> <br>")
     
    # Quit
    app.quit()
