[ACCEPTED]-How to remove an HTML element using the DOMDocument class-domdocument
Accepted answer
In addition to Dave Morgan's answer you 1 can use DOMNode::removeChild to remove child from list of children:
Removing a child by tag name
//The following example will delete the table element of an HTML content.
$dom = new DOMDocument();
//avoid the whitespace after removing the node
$dom->preserveWhiteSpace = false;
//parse html dom elements
$dom->loadHTML($html_contents);
//get the table from dom
if($table = $dom->getElementsByTagName('table')->item(0)) {
//remove the node by telling the parent node to remove the child
$table->parentNode->removeChild($table);
//save the new document
echo $dom->saveHTML();
}
Removing a child by class name
//same beginning
$dom = new DOMDocument();
$dom->preserveWhiteSpace = false;
$dom->loadHTML($html_contents);
//use DomXPath to find the table element with your class name
$xpath = new DomXPath($dom);
$classname='MyTableName';
$xpath_results = $xpath->query("//table[contains(@class, '$classname')]");
//get the first table from XPath results
if($table = $xpath_results->item(0)){
//remove the node the same way
$table ->parentNode->removeChild($table);
echo $dom->saveHTML();
}

DomDocument is a DomNode.. You can just 6 call remove child and you should be fine.
EDIT: Just 5 noticed you were probably talking about 4 the page you are working with currently. Don't 3 know if DomDocument would work. You may 2 wanna look to use javascript at that point 1 (if its already been served up to the client)
