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:
1
2
3
4
5
6
7
8
9
10
11
12
|
< 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>\n" );
walk_tree ( $doc ->root ());
print ( "</pre>\n" );
?>
