PHP往XML中添加节点的方法

本文实例讲述了PHP往XML中添加节点的方法。分享给大家供大家参考。具体方法如下：

1. contacts.xml代码

<contact id="43956">

     <personal>

          <name>

               <first>J</first>

               <middle>J</middle>

               <last>J</last>

          </name>

          <title>Manager</title>

          <employer>National</employer>

          <dob>1971-12-22</dob>

     </personal>

</contact>

2. php代码

<?php

     $tel_node = null;

     $doc = xmldocfile ('contacts.xml');

     $contact_node = $doc->root ();

     $kids = $contact_node->children ();

     while ($node = array_shift ($kids)) {

          if (($node->type == XML_ELEMENT_NODE) && ($node->tagname == 'personal')) {

               $tel_node =& $node;

               break;

          }

     }

     if ($tel_node == null){

          die ("Couldn't locate 'personal' node.");

     }

     $work_node = $tel_node->new_child ('work', '6666');

     print ("<pre>\n");

     print (htmlspecialchars ($doc->dumpmem ()));

     print ("</pre>\n");

?>

希望本文所述对大家的php程序设计有所帮助。
