As of v4.2.2 of PHP, with libxml version 2.4.19, set_content does not replace the content of the node, but only appends to it. Bug, feature, who knows!

To replace the content of a node, create a new node, copy the properties and children of the old node to the new one, then set the content of the new one and use replace_node to put it back into the DoM.

if you had used set_name() to change the node's tag name :

 $newnode =& $dom->create_element( $node->tagname );
should be:
 $newnode =& $dom->create_element(  $node->node_name());

As of 4.3.2:

$names = $contact->get_elements_by_tagname("name");
$name = $names[0];
$name_text_node = $name->first_child();
$name_text_node->set_content("Joe");

does not work.  Currently it looks like dom text nodes are implemented as "domtext", not "domelement" and therefore lack the set_content method.  As far as I've been able to tell, replacing is the best solution.

If you want to set_content which is not in Alphabet, such as big5 charset, you have to use the iconv() to convert your codeset from big5 to something else, such as UTF-8. Here is a example:

$node->set_content(iconv("big5","UTF-8","This is a test.");
$node->set_content(iconv("big5","UTF-8","[Chinese Chars]");

These works find that won't dump garbage chars when your use dump_mem to file.

Ps. don't forget to include the php_iconv.dll

For those transitioning to PHP5 DOM XML code, there is a gotcha with this function.

In PHP4, when you call $node->set_content($string), the $string must have special HTML characters encoded. The method does not properly handle the "&" character, so this is required to properly set the content

In PHP5, when you call $node->appendChild($dom->createTextNode($string)), PHP will properly encode the "&" character without the need for HTML encoding.

Because of this, older code that is currently using htmlspecialchars() in the set_content() call will potentially double-encode the "&" character if you keep the call to htmlspecialchars() in the createTextNode() call.
