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.

/**

* Needed as a workaround for bug/feature of set_content
* This version puts the content

* If you need it somewhere else, simply
* move $newnode->set_content() where
* you want it.
*/
function replace_content( &$node, &$new_content )
{
$dom =& $node->owner_document();
$newnode =& $dom->create_element( $node->tagname );
$newnode->set_content( $new_content );
$atts =& $node->attributes();
foreach ( $atts as $att )
{
$newnode->set_attribute( $att->name, $att->value );
}
$kids =& $node->child_nodes();
foreach ( $kids as $kid )
{
if ( $kid->node_type() != XML_TEXT_NODE )
{
$newnode->append_child( $kid );
}
}
$node->replace_node( $newnode );
}
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.");
$node->set_content(iconv("big5","UTF-8","[Chinese Chars]");
These works find that won't dump garbage chars when your use dump_mem to file.
Ps. don't forget to include the php_iconv.dll
function replace_content( &$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);
}
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.
