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.
