To print the node simply create a new document import the node and save it to html or whatever you need

e.g.:

<?php
$temp = new DOMDocument('1.0', 'UTF-8');
$temp_node = $temp->importNode($mynode, TRUE);
$temp->appendChild($temp_node);
$temp->saveHTML();
?>

Only to correct a very small error, but maybe difficult to find in che function GetContentAsString posted by someone in April 2005.
There was $anode-node_value() instead of $anode->node_value().
This is the right version:

<?php

function GetContentAsString($node) {   
  $st = "";
  foreach ($node->child_nodes() as $cnode)
   if ($cnode->node_type()==XML_TEXT_NODE)
     $st .= $cnode->node_value();
   else if ($cnode->node_type()==XML_ELEMENT_NODE) {
     $st .= "<" . $cnode->node_name();
     if ($attribnodes=$cnode->attributes()) {
       $st .= " ";
       foreach ($attribnodes as $anode)
         $st .= $anode->node_name() . "='" .
           $anode->node_value() . "'";
       }   
     $nodeText = GetContentAsString($cnode);
     if (empty($nodeText) && !$attribnodes)
       $st .= " />";        // unary
     else
       $st .= ">" . $nodeText . "</" .
         $cnode->node_name() . ">";
     }
  return $st;
  }

?>

get_content() always returns UTF-8 (as should be!).
To get the content right just code it like

$myContent = utf8_decode($myNode->get_content());

Works fine!

Seems that get_content() always returns utf-8.
Opening document with something like

$dom->dump_mem(true,"ISO-8859-1")

makes no difference!

Here's a routine I wrote that acts like get_content() but returns embedded XHTML in the string returned.  I needed this as I was wanting to embed HTML formatting codes in my HTML (e.g., "<br />") and converting them to HTML entities or using CDATA was a huge hassle.

<?php

function GetContentAsString($node) {   
  $st = "";
  foreach ($node->child_nodes() as $cnode)
    if ($cnode->node_type()==XML_TEXT_NODE)
      $st .= $cnode->node_value();
    else if ($cnode->node_type()==XML_ELEMENT_NODE) {
      $st .= "<" . $cnode->node_name();
      if ($attribnodes=$cnode->attributes()) {
        $st .= " ";
        foreach ($attribnodes as $anode)
          $st .= $anode->node_name() . "='" .
            $anode-node_value() . "'";
        }   
      $nodeText = GetContentAsString($cnode);
      if (empty($nodeText) && !$attribnodes)
        $st .= " />";        // unary
      else
        $st .= ">" . $nodeText . "</" .
          $cnode->node_name() . ">";
      }
  return $st;
  }
