PHP nodevalue stripping html tags

Question

I have seem similar solutions else where but I haven't been able to convert to work with my own code.

I have a function that splits an html string between the paragraph tags and returns in an array. Code is as follows...

$dom = new DOMDocument();
$dom->loadHTML($string);
$domx = new DOMXPath($dom);
$entries = $domx->evaluate("//p");
$result = array();
foreach ($entries as $entry) {
    $result[] = '<' . $entry->tagName . '>' . $entry->nodeValue .  '</' . $entry->tagName . '>';
}

return $result;

Can someone assist me to remove the nodeValue element from this so it returns the paragraph content with html tags complete?

• A full test of what im doing with the code (as it stands with the suggestion to use ownerDocument->saveHTML applied) is here: http://adam-makes-websites.com/tests/htmltest/runtest.txt

• The output from the test can be seen here: http://adam-makes-websites.com/tests/htmltest/runtest.php

Answer 1

You need to call saveHTML on the ownerDocument property:

$result[] = $entry->ownerDocument->saveHTML($entry);

Answer 2

$dom = new DOMDocument();
$dom->loadHTML($string);
$entries = $dom->getElementsByTagName('p');
$new_dom = new DOMDocument();
foreach ($entries as $entry) {
    $new_dom->appendChild($new_dom->importNode($entry, TRUE));
}
$result = $new_dom->saveHTML()
