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;

  }



?>
