PHP DOM html get element from another element -

i trying create php html dom work element path pattern.

it looks fallow. can have different paths want have text out. like;

$elements = 'h1;span;'; $elements = 'div.test;h2;span'; 

i tried create function handle these inserts stuck on part set 'getelementsbytagname()' in order , receive value of last element,

what have done now;

    function convertname($html, $elements) {          $elements = explode(';', $elements);         $dom = new domdocument;         $dom->loadhtml($html);         $name = null;          foreach ($elements $element) :             $name. = getelementsbytagname($element)->item(0)->;             endforeach;           $test = $dom->$name.'nodevalue';          print_r($test); // receive value              } 

i hope can give me input or examples.

may this:

function convertname($html, $elements) {    $doc = new domdocument();    libxml_use_internal_errors(true);    $doc->loadhtml($html); // loads html    $xpath = new domxpath($doc);     $elements = explode(';', $elements);    $elemvalues = array();     foreach ($elements $element) {       $nodelist = $xpath->query("//$element");       for($i=0; $i < $nodelist->length; $i++)          $elemvalues[$element][] = $nodelist->item($i)->nodevalue;    }    return $elemvalues; }  // testing $html = <<< eof  <span class="bar">some normal text</span>  <input type="hidden" name="hf" value="123">  <h1>heading 1<span> span inside h1</span></h1>  <div class='foo'>some div</div>  <span class="bold">bold text</span>  <p/> eof;  $elements = 'h1;span;'; // replace last ; / valid xpath $elements = preg_replace('#;(?=[^;]*;)#', '/', $elements); // call our function $elemvalues = convertname($html, $elements); print_r($elemvalues); 

output:

array (     [h1/span] => array         (             [0] =>  span inside h1         )  )
