本文实例讲述了php实现的xml操作类。分享给大家供大家参考,具体如下:

new_xml('test.xml');
$test->root('document');
$test->append_root_node('book');
$test->append_child_node('author','linage');
$test->append_child_node('page',100);
$test->append_child_node('money','35 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','35 RMB');
$test->append_root_node_end();
$test->display();
$test->save();
生成的xml结果:

<document>
<book>
<author>linage</author>
<page>100</page>
<money>35 RMB</money>
</book>
<book name="TheWebServers">
<author>li n a g e</author>
<page>100</page>
<money>35 RMB</money>
</book>
</document>
