    $newText = $xmldoc->createTextNode($newActv);

    Change this line to

    $newText = $xmldoc->createTextNode($newAct);

    I think I know what is the problem with your code. You should not write like that: <?xml-stylesheet type="text/xsl" href="sample.xsl" ?> The right code is:

    <?xml:stylesheet type="text/xsl" href="sample.xsl" ?>

    is your code block copy and pasted from your existing files? if so i see two potential issues:

    <form name='input' action'insert.php' method='post'> // should be:
<form name="input" action="insert.php" method="post">

    note: you're missing action="insert.php", which would cause the form to just reload itself without submitting, which is the behaviour you describe.

    secondly, make sure you have write permission to "sample.xml". you can confirm if you're actually writing anything:

    print 'I wrote '.$xmldoc->save('sample.xml').' bytes of data';

    Final Solution

    sample.XML

    <list>
    <activity>swimming</activity>
    <activity>running</activity>
    <activity>Jogging</activity>
    <activity>Theatre</activity>
    <activity>Programming</activity>
</list>

    index.php

    <html>
<head><title>test</title></head>
</head>

<?php
    $xmldoc = new DOMDocument();
    $xmldoc->load("sample.xml", LIBXML_NOBLANKS);

    $activities = $xmldoc->firstChild->firstChild;
    if($activities!=null){
        while($activities!=null){
            echo $activities->textContent."<br/>";
            $activities = $activities->nextSibling;
        }
    }
?>

<form name="input" action="insert.php" method="post">
    insert activity:
    <input type="text" name="activity"/>
    <input type="submit" value="send"/>
</form>
</body>
</html>

    insert.php

    <?php
    header('Location:index.php');
    $xmldoc = new DOMDocument();
    $xmldoc->load('sample.xml');

    $newAct = $_POST['activity'];

    $root = $xmldoc->firstChild;

    $newElement = $xmldoc->createElement('activity');
    $root->appendChild($newElement);
    $newText = $xmldoc->createTextNode($newAct);
    $newElement->appendChild($newText);

    $xmldoc->save('sample.xml');
?>

    Actually you made mistakes in two places.

    This line should be I think because of the typo, you missed an equal sign. Also

    These lines should be

    Try now, it should work, Hop this would make some sense
