@$doc2->loadHTMLFile('http://www.web-source.net/html_codes_chart.htm');

 

$bold_text = array();

$bold_text2 = array();

 

$bold_elements = $doc->getElementsByTagName('b');

foreach($bold_elements as $element)

You are using it wrong. Check the manual: http://php.net/manual/en/domnode.removechild.php

 

It should be:

$parentObject->removeChild($childObject);

ya ..u are right .... but there is another problem too ..right now i am only deleting only the variable  ...but i should be removing the node instead  ..

i should  create a DOMNodeList with matching text cotent .. how do i do it ..

 

i did this to make A DOMNodeList of links with a matching href attribute using xpath and it works but i dont know how to create a DOMNodeList with matching text cotent ..please help

 
foreach ($srcBoth as $src)
{ // Loops through the src strings that are common to both documents
    $imgs = $xpath->query('//a[@href="'.$src.'"]'); // A DOMNodeList of links with a matching href attribute
    foreach ($imgs as $img) 
{ 
// Loops through the links
$img->parentNode->removeChild($img);
}
