Menu
I am trying to get the innerhtml of div tags in a file using nodeValue, however this code is outputting only plain text and seems to strip out all html tag from inside the div. How can I change this code to output the div's HTML content and not plain text, AND also output the main div wrapping it's child elements.
Example:
contents of file.txt:
<div class="1"><span class="test">text text text</span></div>
<div class="2"><span class="test">text text text</span></div>
<div class="3"><span class="test">text text text</span></div>
script.php:
$file= file_get_contents('file.txt');
$doc = new DOMDocument();
@$doc->loadHTML('<?xml encoding="UTF-8">'.$file);
$entries = $doc->getElementsByTagName('div');
for ($i=0;$i<$entries->length;$i++) {
$entry = $entries->item($i);
echo $entry->nodeValue;
}
outputs: text text texttext text texttext text text
what I need it to output:
<div class="1"><span class="test">text text text</span></div>
<div class="2"><span class="test">text text text</span></div>
<div class="3"><span class="test">text text text</span></div>
Notice the parent div's (..etc) are needed to be outputted as well wrapping the span tags...
HELP!

I have never done what you're attempting to do, but as a stab in the dark, using the API docs, does echo $entry->textContent; work?
Adding an update. This is from the comments located on the docs page for DOMNode:
Hi!
Combining all th comments, the easiest way to get inner HTML of the node is to use this function:
<?php function get_inner_html( $node ) {
$innerHTML= '';
$children = $node->childNodes;
foreach ($children as $child) {
$innerHTML .= $child->ownerDocument->saveXML( $child );
}
return $innerHTML; } ?>
Or, maybe a simpler method is just to do:
echo $domDocument->saveXML($entry);
Instead of:
echo $entry->nodeValue;
You have to use:
echo $doc->saveXML($entry);
Here is a more complete example that might help others too, $doccontent is the HTML block as a string:
$doccontent = '<html> …'; // your html string
$dom = new DOMDocument;
$internalErrors = libxml_use_internal_errors(true); // prevent error messages
$content_utf = mb_convert_encoding($doccontent, 'HTML-ENTITIES', 'UTF-8'); // correct parsing of utf-8 chars
$dom->loadHTML($content_utf);
libxml_use_internal_errors($internalErrors); // prevent error messages
$specialdiv = $dom->getElementById('xdiv');
if(isset($specialdiv))
{
echo $dom->saveXML($specialdiv);
}
