PHP错误加载，编辑然后保存XML DOMDocument

Question

I am getting the following output when running a simple script which loads a XML file, adds a node with a few child nodes to the document, then saves the XML file. Here is the link to this XML file being referenced: http://msgrapp.com/test/ajaxchat/messages.xml

Warning: DOMDocument::load(): Extra content at the end of the document in /home1/dstamp/public_html/messages.xml, line: 3 in /home1/dstamp/public_html//sendMessage.php on line 4

<?php
    $doc = new DOMDocument('1.0');
    $doc->load('messages.xml');

    $root = $doc->createElement('MESSAGE');
    $root = $doc->appendChild($root);

    $dateNode = $doc->createElement('DATE');
    $dateNode = $root->appendChild($dateNode);
    $dateText = $doc->createTextNode(date("F j Y g:i a"));
    $dateText = $dateNode->appendChild($dateText);

    $senderNode = $doc->createElement('SENDER');
    $senderNode = $root->appendChild($senderNode);
    $senderText = $doc->createTextNode($_GET['sender']);
    $senderText = $senderNode->appendChild($senderText);

    $messageNode = $doc->createElement('TEXT');
    $messageNode = $root->appendChild($messageNode);
    $messageText = $doc->createTextNode($_GET['message']);
    $messageText = $messageNode->appendChild($messageText);

    $doc->save('messages.xml');
    echo $doc->saveXML();
?>

Answer 1

The extra content error is caused by having two of the same node, in this case the MESSAGE node, as a root element.

You could add a new root element MESSAGES for example, and then add more MESSAGE elements within that

This will Help you : Alternately getting the error (Extra content at the end of the document )
