I am working on a script which is getting data from HTML DOM elements.
Here is my code:
$url = 'http://www.sportsdirect.com/nike-satire-mens-skate-shoes-242188?colcode=24218822';
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXpath($doc);
$Name = $xpath->query('//span[@id="ProductName"]')->item(0)->nodeValue;
echo $Name;
This code is simply taking the text inside <span id="ProductName"></span>
. I know how to get the data from elements with specific class or id.
I don't know how I can get the src="http://adres-to-image.com/img.png"
(pure example) from image tag or how I can get elements which do not have id or class but have attribute like itemprop
, for example <div itemprop="name"></div>
src
? itemprop
? For your examples:
$xpath->query('//img/@src)->item(0)->nodeValue
This means
Select all src attributes of all img tags and get the value of the first
$xpath->query('//div/[@itemprop="name"])->item(0)->nodeValue
This means
Select all divs with itemprop attr equals name and get the value of the first.
You just look for the attributes:
$url = 'http://www.sportsdirect.com/nike-satire-mens-skate-shoes-242188?colcode=24218822';
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXpath($doc);
$Name = $xpath->query('//div[@class="productImageSash"]');
foreach($Name as $element){
$imgs = $element->getElementsByTagName('img');
foreach($imgs as $img){
$src = $img->getAttribute('src');
echo $src;
}
}
Output:
/images/sash/productsash_mustgo.png
The same with itemprop
attribute, look for divs which have this attribute:
$Name = $xpath->query('//div');
foreach($Name as $element){
$itemprop = $element->getAttribute('itemprop');
if($itemprop){
echo "found";
}
}
