`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.`

`function replace_content( &$node, $new_content )
{
$dom = &$node->owner_document();
$kids = &$node->child_nodes();
foreach ( $kids as $kid )
if ( $kid->node_type() == XML_TEXT_NODE )
$node->remove_child ($kid);
$node->set_content($new_content);
}`

`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`

`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 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());`

`Actually, don't forget that the text is actually a child node of the given element. The domxml coders decided to append to the content in the case that this function is called on a node which has children (to avoid a crash), but you shouldn't normally call it that way.
For example, if your document had:
<contact>
<name>Eric</name>
</contact>
and you wanted to change the content of the name element and $contact is the contact node, then you would use:
$names = $contact->get_elements_by_tagname("name");
$name = $names[0];
$name_text_node = $name->first_child();
$name_text_node->set_content("Joe");
Hope this clarifies things. Removing nodes, and inserting new ones is not an efficient solution :)
Cheers,
Eric`

`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.
