本文实例讲述了PHP遍历XML文档所有节点的方法。分享给大家供大家参考。具体实现方法如下:
1. contact.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 function walk_tree ($node, $depth = 0) { for ($i = 0, $indent = ''; $i < $depth; $i++) $indent .= ' '; if ($node->type == XML_ELEMENT_NODE) { print ($indent . $node->tagname . "\n"); $kids = $node->children (); $nkids = count ($kids); if ($nkids > 0) { $depth++; for ($i = 0; $i < $nkids; $i++) walk_tree ($kids[$i], $depth); $depth--; } } } $doc = xmldocfile ('contact.xml'); print ("<pre class="brush:php;toolbar:false">\n"); walk_tree ($doc->root ()); print ("\n"); ?>
希望本文所述对大家的php程序设计有所帮助。
