XML operation classes implemented by PHP

This paper describes the XML operation classes implemented by PHP. Share to everyone for your reference, as follows:

<?php/* Use method: $test =new XML (), $test->new_xml (' Test.xml '); $test->root (' document '); $test->append_root_ Node (' book '), $test->append_child_node (' author ', ' Linage '), $test->append_child_node (' page '), $test- Append_child_node (' Money ', ' RMB $ '), $test->append_root_node_end (); $test->append_root_node (' book ', ' Name ', ' The "Web" Servers '); $test->append_child_node (' A U T Ho "R ', ' Li n a G e '); $test->append_child_node (' page ', 100); $ Test->append_child_node (' Money ', ' RMB $ '), $test->append_root_node_end (), $test->display (), $test Save (); generated XML result: <?xml version= "1.0" encoding= "Utf-8"?>
