Grabbing the href attribute of an A element

I’m currently trying to parse a webpage for a specific element which will be in this format:

<div id="main-id">
    <div id="sub-id-1" onclick="some onclick"> 
    <span class="big-class" style="some style">
    </span>
    <div id="sub-id-2">&#160;</div>
</div>

The main part I’m trying to pull from this is the entire <span class="big-class" style="some style"> tag, as I need to pull the style from the element and store it to a string. To do this, I tried using the following code:

$dom = new DOMDocument();
$dom->validateOnParse = true;
$dom->loadHTML($html);

$belement = $dom->getElementById("main-id");
echo $belement->nodeValue;

However, this is only returning the character Â, which is what the character code &#160 is for.

I’m not really sure what to search for in order to accomplish this, and I’m not even sure if pull entire HTML lines(?) with DOM. Is there any way I could use DOM to return this span element?

Answer 1

nodeValue will return the innerHTML for your tag. So, in this case it rightly returns Â. You can check PHP Xpath : get all href values that contain needle for a similar discussion. You can do this:

$html = <<< HTML
<div id="main-id">
    <div id="sub-id-1" onclick="some onclick"> 
    <span class="big-class" style="some style">
    </span>
    <div id="sub-id-2">&#160;</div>
</div>
HTML;

$xml  = simplexml_load_string($html);
$span_elem = $xml->xpath('//span[@class="big-class"]');
