how to get div class value using dom document

Question

i need to echo this value 4,458 members

from the below code

< div class="mbs fcg">4,458 members< /div>

right now my orginal code is

$links = $dom->getElementsByTagName('div');

It is unclear what you want: 1) you ask to target a `class value`. 2) You want to echo a `text-node` ... So, what do you actually want? — Ole Sauffaus, Jul 19 '15 at 06:18

you will need to use DOMXPath, which will take a DOMDocument instance

$xpath   = new DOMXPath( $dom );
// if the className doesn`t changes
$members = $xpath->query( '//div[@class="mbs fcg"]' );
// if the class name changes ex. class="mbs fcg my-other class-name"
$members = $xpath->query( '//div[contains(@class,"mbs fcg")]' );

alternatively if you want to iterate all over your div`s you could try

$divs = $dom->getElementsByTagName( 'div' );
foreach( $divs as $div ){
    // if the className doesn`t changes
    if( $div->getAttribute( 'class' ) === 'mbs fcg' ){
        echo $div->nodeValue;
    }
    // if the class name changes ex. class="mbs fcg my-other class-name"
    if( strpos( $div->getAttribute( 'class' ), 'mbs fcg' ) !== false ){
        echo $div->nodeValue;
    }
}

your welcome, i'm glad i could help you out. you should also mark it as right answer — Mujnoi Gyula Tamas, Jul 21 '15 at 10:15

NOTICE::: THIS IS A JAVASCRIPT SOLUTION ... NOT A PHP DOMDOCUMENT SOLUTION

Try this HTML:

<div id="ME" class="mbs fcg">4,458 members</div>

... and this Javascript:

var WANTED_TEXT = document.getElementById('ME').firstChild.nodeValue;

EDIT2:

If you actually want, to get all textnodes from all occurrences of elements having class='mbs cfg' ... then try the following HTML:

<div class="mbs fcg">4,458 members</div>

... and this Javascript:

var Collection = document.getElementsByClassName('mbs fcg');

for(i=0; i<Collection.length; i++) {
    Texts = Collection[i].firstChild.nodeValue;
    document.write('<p>'+Texts+'</p>');
}

That should echo the pure text from all elements in the Collection.

I havn't tried myself ... But, I would think so, yes. – Ole Sauffaus Jul 19 '15 at 06:47
Ohhh ... this is PHP only ... sorry ... I didn’t notice that! ... You should disregard my answer, which is a JavaScript solution. – Ole Sauffaus Jul 19 '15 at 06:57
its ok sir, do u have any id how we can write in php – only chande Jul 19 '15 at 07:04
I read, that DOMDocument doesn't offer a method `getElementsByClassName` to select by `class`, but only offers selection either by `id` or by `tagName` ... that means you need to collect all divs, and then iterate to find your class-names by string-comparison or regex. – Ole Sauffaus Jul 19 '15 at 07:12

I think you need to use an id to target a single div, such as:

< div id="my_id_name" class="mbs fcg">4,458 members< /div>
