Simple dom php parse get custom data attribute value

Question

HTML:

<div class="something" data-a="abc">ddsf</d>

PHP:

foreach ($dom->find('.something[data-rel]') as $this) {
    var_dump($this->attr());

I tried this but error. Couldn't find any info on its documentation. I want to get the data-a's value which is abc.

Your code makes no sense at all, you probably want to do this with javascript. – Industrious

@JelleKeizer why? If u wonder why 1 element need a foreach, actually that is just an example – Tayyebeb

the question is straight to the point, how to get custom data attribute value in simple php dom parser. – Tayyebeb

Sorry was misreading it, did you try getAttribute('data-a'); – Industrious

Answer 1

Why not just use the well-documented, built in, DOM extension?

Example:

$html = '<div class="something" data-a="abc">ddsf</div>';

$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);

$nodes = $xpath->query('//div[@class="something"]/@data-a');
foreach ($nodes as $node) {
    var_dump($node->value);
}

Output:

string(3) "abc"

Answer 2

It looks like this:

$dom->find('div[data-a]',0)->{'data-a'}

how bout $dom->find('div[data-a]')->{'data-a'} ? the zero is optional right? because assume I can do like this $dom->find('.panel [data-a]')->{'data-a'} – Tayyebeb

No, the 0 means the first match. Without the 0 you get an array. – Saddlebag

I couldn't for the life of me find this in the docs. Thank you so much! – Devote

Answer 3

use

foreach($html->find('button') as $element) 
   echo $element->{'data-coupon'};

Answer 4

Use xpath

Should be something like this:

foreach ($dom->xpath('/div[@data-a]') as $item) {
    ...
}

are you sure? this is like getting the right element, is this the way u get the value the custom attr? – Tayyebeb

No, this way you find and loop through all 'div' elements that have "data-a" attribute. To get the value of this attribute you just need to access $item->attributes()->{'data-a'} – Prognosticate
