Question

I am using curl to fetch website content into a variable. Now, using either the ‘url’ or the fetched content i want to extract all the <p> tags into a variable.
Can anyone guide me on this ?

After hours i have just been able to create a DOM Document in php !

This is the code i have written:

$domDoc = new DOMDocument();
$domDoc->loadHTML($content);

print_r($domDoc);

$paragraphs = $domDoc->getElementsByTagName("p");
foreach ($paragraphs as $paragraph)
    $paragraph->item(0)->nodevalue;

where $content contains the website content fetched using

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url[url]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xml_contents = curl_exec ($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close ($ch);
$website_content = $xml_contents;

Can someone please guide me ?

You don’t need to use item() in the foreach loop. Simply access nodeValue directly from the $paragraph variable to get the content of the p tag.

You’ll want to use item() only if you’re using a normal for loop.

for ($i = 0; $i < $paragraphs->length; $i++) 
{
    echo $paragraphs->item($i)->nodeValue;
}
