#4921 — DOMDocument HTML problem

Hi, I am trying to take an incomplete "summary"  of a number of characters 
of an HTML fragment without DOCTYPE, HTML, or BODY elements and a possibly 
incomplete unbalanced fragment, and convert it to a ballanced fragment 
without DOCTYPE, HTML, or BODY, using DOMDocument and friends.

This is what I have got (it works without a Error 500 using php command line 
tool :-

~~~~
<?php

$html = '<div>
<p><a href="#test">foo</a></p>
<hr>
<br>
<div>name</div>
';

$dom = new DOMDocument();
$newdom = new DOMDocument();

$dom->loadHTML($html);

$Elements = $dom->childNodes;

foreach ( $Elements as $Element ) {

    $NewElement = $newdom->createElement($Element->nodeName);

    if ($Element->attributes)
      foreach($Element->attributes as $attribute)
        $NewElement->setAttribute($attribute->name, $attribute->value);

    if ($Element->childNodes)
      foreach($Element->childNodes as $child)
        $NewElement->appendChild( $newdom->importNode($child, true));

    $newdom->appendChild( $NewElement);
}

echo $newdom->saveHTML();
?>
~~~~

It balances the unbalanced <div> seems to be adding a duplicate 
<HTML></HTML> at the beginning of the output.

Also I need to get the fragment of the code like a JavaScript DOM innerHTML 
without the <HTML> and <BODY> tags.

Many thanks in advance.

Hope you can help,

Aaron

If your document is not well formed, DOMDocument has to guess at what it 
the document is supposed to represent.  Results are likely to be rather 
indeterminate.

This doesn't mean you need DOCTYPE, <head>, <body>, etc., but things 
like unbalanced <div> tags are likely to cause problems.

$html = trim( preg_replace( '/\s\s+/', '', $html));

echo $html . "\n\n";

$xpath = new DOMXPath($dom);

$body = $xpath->query('/html/body/*');

echo $dom->saveXml($body->item(0));

This does the job !
