html - to manipulate the DOM of the current page using PHP? -


i know how manipulate dom of current page using php. explanation below:

this code in php file:

<div id="edittitle" title="editing title"> <b>1</b> </div> $strhtml=;     libxml_use_internal_errors( true );     $dom=new domdocument('1.0','utf-8');     $dom->validateonparse=false;     $dom->loadhtml( $strhtml );     libxml_clear_errors();     $col=$dom->getelementsbytagname('b');     echo $col->item(0)->nodevalue;

actually, want putting whole html code exists in current file (the php file) in variable $strhtml (please focus on following line of code: $strhtml=;). there idea how that?

thanks in advance.

if want can putting of html in output buffer while / before sending browser (the latter can done output control). can dom parse "captured" html.

but should ask trying achieve , if not better suited client-side (i.e. javascript) code.
