"<something />"; // it will be erased $o = domxml_open_mem($gsXML); $something = $o->document_element();//obtaining node to delete //echo("before:<pre>\n". print_r($o->dump_mem(true),true). "</pre>\n"); $something->unlink_node($something); // deleting node //echo("after:<pre>\n". print_r($o->dump_mem(true),true). "</pre>\n"); ?> and it was error like this Fatal error: Call to undefined function: domxml_open_mem() in c:\appserv\www\k\testdom.php on line 4 How can I solve problem?
