Although it may be preferable to use the dom to manipulate elements, sometimes it's useful to actually get the innerHTML from a document element (e.g. to load into a client-side editor).





To get the innerHTML of a specific element ($elem_id) in a specific html file ($filepath):





<?php


$innerHTML = '';


$doc = new DOMDocument();


$doc->loadHTMLFile($filepath);    


$elem = $doc->getElementById($elem_id);





// loop through all childNodes, getting html        


$children = $elem->childNodes;


foreach ($children as $child) {


    $tmp_doc = new DOMDocument();


    $tmp_doc->appendChild($tmp_doc->importNode($child,true));        


    $innerHTML .= $tmp_doc->saveHTML();


}


?>

Hi to get the value of DOMElement just get the nodeValue public parameter (it is inherited from DOMNode):

<?php 

echo $domElement->nodeValue; 

?>

Everything is obvious if you now about this thing ;-)

Caveat!

It took me almost an hour to figure this out, so I hope it saves at least one of you some time.



If you want to debug your DOM tree and try var_dump() or similar you will be fooled into thinking the DOMElement that you are looking at is empty, because var_dump() says: object(DOMElement)#1 (0) { } 



After much debugging I found out that all DOM objects are invisible to var_dump() and print_r(), my guess is because they are C objects and not PHP objects. So I tried saveXML(), which works fine on DOMDocument, but is not implemented on DOMElement.



The solution is simple (if you know it):

$xml = $domElement->ownerDocument->saveXML($domElement);



This will give you an XML representation of $domElement.

I wanted to find similar Elements - thats why I built an Xpath-String like this - maybe somebody needs it... its not very pretty - but neither is domdocument :)





<?php





$dom->load($xmlFile))





$xpathQuery = '//*';


$xmlNodes = $xpath->query($xpathQuery);


        


$pathlist = array();


$attrlist = array();


foreach ($xmlNodes as $node) {





  $depth = $this->_getDomDepth($node);   //get Path-Depth (for array key)


  $pathlist[$depth] = $node->tagName;     // tagname


          


  $attrs = $node->attributes;


  $attr='';


  $a=0;


  foreach ($attrs as $attrName => $attrNode)  // attributes


            {


              if ($attrName !='reg')


              {


                if ($a++!=0) $attr .= ' and ';


                $attr .= '@'.$attrName.'='."'".$attrNode->value."'";


              }


            }


          


          $attrlist[$depth] = $attr?'['.$attr.']':'';


          


          $path = ''; for ($i=0;$i<=$depth;$i++) $path .= '/'.$pathlist[$i].$attrlist[$i];  // the xpath of the actual Element





    // ... now you can go on and user $path to find similar elements


    }


  }


}





 private function _getDomDepth(DomNode $node)


   {


     $r = -2;


     while ($node) {


       $r++;  


       $node = $node->parentNode;


     } 


     return  $r;


   }


?>

Hi there.



Remember to append a DOMNode (or any of its descendants) to a DOMDocument __BEFORE__ you try to append a child to it.



I don't know why it has to be this way but it can't be done without it.



bye
