I'm trying to parse a document and get all the image tags and change the source for something different.
$domDocument = new DOMDocument();
$domDocument->loadHTML($text);
$imageNodeList = $domDocument->getElementsByTagName('img');
foreach ($imageNodeList as $Image) {
$Image->setAttribute('src', 'lalala');
$domDocument->saveHTML($Image);
}
$text = $domDocument->saveHTML();
The $text initially looks like this:
<p>Hi, this is a test, here is an image<img src="http://example.com/beer.jpg" width="60" height="95" /> Because I like Beer!</p>
and this is the output $text:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><p>Hi, this is a test, here is an image<img src="lalala" width="68" height="95"> Because I like Beer!</p></body></html>
I'm getting a bunch of extra tags (HTML, body, and the comment at the top) that I don't really need. Any way to set up the DOMDocument to avoid adding these extra tags?

You just need to add 2 flags to the loadHTML() method: LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD. I.e.
$domDocument->loadHTML($text, LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD);
See IDEONE demo:
$text = '<p>Hi, this is a test, here is an image<img src="http://example.com/beer.jpg" width="60" height="95" /> Because I like Beer!</p>';
$domDocument = new DOMDocument;
$domDocument->loadHTML($text, LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD);
$imageNodeList = $domDocument->getElementsByTagName('img');
foreach ($imageNodeList as $Image) {
$Image->setAttribute('src', 'lalala');
$domDocument->saveHTML($Image);
}
$text = $domDocument->saveHTML();
echo $text;
Output:
<p>Hi, this is a test, here is an image<img src="lalala" width="60" height="95"> Because I like Beer!</p>
