Select value instead of text from option + XML DOM

Question

I'm trying to get the values of a select list with the name = Reeks that you can find on this page: http://www.volleyvvb.be/?page_id=1083. The select list looks like this:

<select class="vvb_tekst_middelkl" name="Reeks" onchange="this.form.submit();">
    <option value="%" selected="">ALLE REEKSEN</option>
    <option value="Liga A H">ETHIAS VOLLEY LEAGUE</option>
    <option value="Liga B H">LIGA B HEREN</option>
    <option value="Ere D">LIGA A DAMES</option>
    ...
</select>

This is how I get the select list:

$html = file_get_contents("http://www.volleyvvb.be/?page_id=1083");

$crawler = new Crawler($html);

$crawler = $crawler->filter("select[name='Reeks']");
foreach ($crawler as $domElement) {
    foreach($domElement->childNodes as $child) {
        $value = $child->nodeValue;
        var_dump($value);
    }
}

What I see now is all the lines between the <option></option> like ALLE REEKSEN, ETHIAS VOLLEY LEAGUE. But I would also like the values like Liga A H, ... How can I select them?

Answer 1

The following code

<?php
require_once("resources/simple_html_dom.php");
$html = file_get_contents("http://www.volleyvvb.be/?page_id=1083");
$doc = str_get_html($html);

$select = $doc->find("select[name='Reeks']");
foreach ($select as $domElement) {
    $child = $domElement->find('option');
    foreach($child as $option) {
        echo $option->getAttribute('value')."<br>";
    }
}
?>

gives me the output you requested.

Liga A H
Liga B H
Ere D
...

An equivalent for the DomCrawler Component would be

$value = $child->nodeValue; // LIGA B HEREN, ...
$attribute = $child->attr('value'); // Liga B H, ...
