Recently I am working with the scraping of data from external URL and for scraping we always need to use a preg_match function to get matched data.
I want to fetch all “div” tags and their respective content and nested div’s through PHP function and I have used preg_match, but it’s creating an issue.
For example, I have syntax for HTML tags something like below
1 2 3 4 5 6 7 |
In from above code, I want to get everything within the div class=’xyz’ but preg_match function going to stop executing after getting the first tag.
So, I have used DOMDocumen for fetching all nested divs value within div class=’xyz’ using the nodeValue element of DOMDocument but it is not returning HTML tags within the div tag.
Here, I am going to explain how I solve above issue when try to fetch multiple nested divs in PHP so let’s see the code.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | function nestedHTML($node) { $doc = $node->ownerDocument; $frag = $doc->createDocumentFragment(); foreach ($node->childNodes as $child) { $frag->appendChild($child->cloneNode(TRUE)); } return $doc->saveXML($frag); } $html = "<div class='xyz'><div class='abc'>contents</div></div>"; libxml_use_internal_errors(true); // if any warning generate $doc = new DOMDocument(); $doc->loadHTML($html); $doc->saveHTML(); $nodes = $doc->getElementsByTagName('div'); foreach ($nodes as $node) { $class = $node->getAttribute('class'); if($class == 'xyz'){ echo nestedHTML($node); } } |
That’s it. you just need to change URL or code require to display.
