I have a variable$contentcontaining a piece of HTML code :
<b>AMZN 466.00 ( 15743 ) ( <span class='red'> -1 </span>)
MSFT 290.00 ( 37296 ) ( <span class='red'> -2 </span>)
TWTR 4,000.00 ( 20 ) ( <span class=''> 0 </span>)</b>Now, I want the values of <b>excluding the values of <span> using PHP DOM. How can this be done? A code snippet would be helpful.
So far, I've tried this:
$dom = new domDocument;
@$dom->loadHTML($content);
$contents_i_want = $dom->getElementsByTagName('b');
foreach($contents_i_want as $content_i_want){
$filtered_content = $content_i_want->nodeValue;
echo $filtered_content;
}
Hope this will help you out..
<?php
ini_set('display_errors', 1);
$string='<html><body><b>AMZN 466.00 ( 15743 ) ( <span class=\'red\'> -1 </span>)
MSFT 290.00 ( 37296 ) ( <span class=\'red\'> -2 </span>)
TWTR 4,000.00 ( 20 ) ( <span class=\'\'> 0 </span>)</b></body></html>';
$dom = new DOMDocument();
$dom->loadHTML($string);
$dom->getElementsByTagName("b");
$xpath= new DOMXPath($dom);
$result=$xpath->query("//b/span");//here we are querying domdocument to find span which is inside b.
$nodesToRemove=array();//here we are maintaining an array of nodes which we want to remove
foreach($result as $node)
{
$node->parentNode->removeChild($node);//removing nodes from its parent
}
echo $dom->getElementsByTagName("b")->item(0)->textContent;//displaying content after removing nodes.
Output:
AMZN 466.00 ( 15743 ) ( )
MSFT 290.00 ( 37296 ) ( )
TWTR 4,000.00 ( 20 ) ( )
