get_body_inter_prefix

get_body_inter_prefix($prefix1,$prefix2,$as_html=true); - get the part of the page body between the specified prefixes (strings)

the input Function accepts parameters:

  • $prefix1 – the start line to be found in the page body
  • $prefix2 – the end line to be found in the page body (after the start line)
  • $as_html – when searching and displaying results, treat the page body as html (true) or just as text (false)

    After testing, the function returns the result of its work to the script :
  • part of the Page body – the specified part of the body of the current page

    PHP example:

    <?php $xhe_host = "127.0.0.1:7013";
    //+ cef
    //connect the object to control the emulator, if not already connected
    if(!isset($path))
       $path = "../../../Templates/xweb_human_emulator.php";
    require($path);
     
    //Start
    echo "<hr> <font color = blue> webpage->".basename(__FILE__)."</font> <hr>";
     
    //1
    echo "1.Let's go to yandex.ru:";
    echo $browser->navigate("http://yandex.ru")."<br>";
     
    //2
    echo "2.Display what the browser has generated(search by html):";
    echo strlen($webpage->get_body_inter_prefix("Yandex", "-", true))."<br>";
     
    //3
    echo "3.Display what the browser has generated(search by text):";
    echo strlen($webpage->get_body_inter_prefix("-", "-", false));
     
    //end
    echo "<hr> <br>";
     
    //Quit
    $app->quit();
    ?>

    Python example:

    # Additional paths
    import sys
    sys.path.insert(0, '../../../Templates PY/')
     
    xhe_host = "127.0.0.1:7013"
    from xweb_human_emulator import *
     
    # Start
    echo("<hr> <font color = blue> webpage.xxxxxxxxx </font> <hr>")
     
    # 1
    echo("1.Let's go to yandex.ru:")
    echo(browser.navigate("http://yandex.ru"), "<br>")
     
    # 2
    echo("2.Display what the browser has generated(search by html):")
    echo(len(webpage.get_body_inter_prefix("Yandex", "-", true)), "<br>")
     
    # 3
    echo("3.Display what the browser has generated(search by text):")
    echo(len(webpage.get_body_inter_prefix("-", "-", false)))
     
    # end
    echo("<hr> <br>")
     
    # Quit
    app.quit()
