php open modify and save html file

Question

in php I would like to open a html file, delete the content of the div(class Areas) and save it.

$dom = new DOMDocument;
$dom->loadHTMLFile( \"temp/page\".$y.         


        

Answer 1

You were very nearly there. You just needed to change Areas to Area and then use saveHtmlFile instead of saveHTML:

$dom = new DOMDocument;
$dom->loadHTMLFile( "temp/page".$y.".xhtml" );
$xpath = new DOMXPath( $dom );
$pDivs = $xpath->query(".//div[@class='Area']");
foreach ( $pDivs as $div ) {
  $div->parentNode->removeChild( $div );
}
$dom->saveHTMLFile("temp/page".$y.".xhtml");

This is assuming you want to save the HTML back to the original document. Do note that DOMXPath will add a doctype to the top of your document, I assume that's okay?
