Questions:
This is code sample that works
$doc->loadHTML($article_header);
$imgs = $doc->getElementsByTagName('img');
foreach ($imgs as $img) {
$imgs takes from $doc elements with tag name img and then I do some operations.
Now I want to getElementsByTagName > img OR iframe and then using $img check which element is this and echo if it is iframe or img.
Please modify my code if it is possible.
How to&Answers:
You can use XPath on your DOMDocument as follows:
$doc->loadHTML($article_header);
$xpath = new DOMXpath($doc);
$imagesAndIframes = $xpath->query('//img | //iframe');
$length = $imagesAndIframes->length;
for ($i = 0; $i < $length; $i++) {
$element = $imagesAndIframes->item($i);
if ($element->tagName == 'img') {
echo 'img';
} else {
echo 'iframe';
}
}
Answer：
It is better to use the following way, because by using this code, you will not get any error if there is no “iframe” / “img” tag present in the object “$doc” (as you are perfectly checking the existence of any elements using the “count()” function):-
$doc->loadHTML($article_header);
$imgs = $doc->getElementsByTagName('img');
$iframes = $doc->getElementsByTagName('iframe');
if (count($imgs)) {
foreach ($imgs as $img) {
// Do some logic on "img" tag
}
}
if (count($iframes)) {
foreach ($iframes as $iframe) {
// Do some logic on "iframe" tag
}
}
Hope it helps.
