How to get the value of "title" using php DOM Document?

<div class='lovers_list'><a href="/laetizia.coronet" class="avatar_tiny tooltip s " title="laetizia.coronet"><img alt="laetizia.coronet" class="avatar" height="24px" src="https://my-secondlife.s3.amazonaws.com/users/laetizia.coronet/tiny_sl_image.png?5d0d6c32c74d8bbe6a606279ef95dee5" width="24px" /></a>

so far ive got..

$dom = new DOMDocument;
@$dom->loadHTMLFile('file.html');
$divs=$dom->getElementsByTagName('div');
foreach($divs as $div){  

 if ($div->getAttribute('class') == "lovers_list")   {   

}

thank you

Does the $div variable contain a reference to the correct div in your if statement? I often find it helpful to use var_dump() on objects which are coming from things like this, as it lets you know what child objects, etc, it contains, and gives you and idea of how you can reference them. I've not used DOMDocument myself, but I would imagine that you could get the link object with:

$a = $div->getElementsByTagName('a');

but I'm sure there's a more efficient and better way of doing this.

You could for example use the language designed for DOM navigation.

$xpath = new DOMXPath($dom);
$titles = $xpath->evaluate("//div[@class='lovers_list']/a/@title", $dom);
foreach($titles as $title)
{
	$title_value = $title->textContent;
	var_dump($title_value);
}

It could be simpler if there is exactly one "title" (as suggested by the wording of the original post).

$title = $xpath->evaluate("string(//div[@class='lovers_list']/a/@title)", $dom);
var_dump($title);

thank you both for your replies..

removed reply as WeedPacket solved the issue in his Edit while i was replying..

Thank you, have a great day 🙂

And if every anchor tag has a title, it'd be something like:

$dom = new DOMDocument; 
@$dom->loadHTMLFile('file.html'); 
$anchors=$dom->getElementsByTagName('a'); 
foreach($anchors as $a){   

 echo $a->getAttribute('title');    

}

Got a RESOLVED tag for this yet? 😉 😉

I realise that there is more than 1 instance of "lovers_list" div on the page.. i only wish to evaluate the 1st instance of "lovers_list".
Please can anyone modify WeedPackets excelent Xpath evalution to only return the 1st "lovers_list" ?

$xpath = new DOMXPath($dom); 
$titles = $xpath->evaluate("//div[@class='lovers_list']/a/@title", $dom); 
foreach($titles as $title) 
{ 
    $title_value = $title->textContent; 
    var_dump($title_value); 
}

Thank you 🙂

//div[@class='lovers_list']/a/@title[1]

and see also the shorter code in my first reply.

Alternatively, note that [font=monospace]$titles[/font] is a [man]DOMNodeList[/man], the interface of which, though small, has everything necessary for the task.
