php读取树型xml文件实现类
XML 函数允许我们解析 XML 文档,但无法对其进行验证,XML 是一种用于标准结构化文档交换的数据格式.
php读取树型xml文件实现类代码如下:
<?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");<!-- <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> -->
