$doc = new DOMDocument(1.0);
$doc -> loadHTMLFile('XmlDomHtml.html');
$head = $doc-> getElementsByTagName('head');
$body = $doc-> getElementsByTagName('body');
getTitle($head);
parseBody($body);

function getTitle($head){
foreach ($head as $header){
if($header->tagName == 'title'){
echo ("网页标题：{$header->textContent}<br />");
}
}
}

function parseBody($Body){
$bodyTag = $Body-> item(0);
foreach ($bodyTag->childNodes as $element){
$content=htmlspecialchars($element->textContent);
switch ($element->tagName){
case 'h2':
echo "标题2：{$content}<br />";
break;

function parseSelect($select){

echo "</li>";
}
echo '</ul>';
}

巧了 昨天刚刚做的实验

<?php
//预先准备的数组，可以从数据库中抽取出来
$array = array(
array ('title'=>'Google',
'link'=>'http://www.google.com/',
'desc'=>'全球第一大搜索引擎，社我其谁！'
),
array(
'title'=>'Baidu',
'link' =>'http://www.baidu.com/',
'desc' =>'中国最大的搜索引擎，谁与争锋！'
)
);
header('content-Type: application/xml;charset=utf-8');
//显示XML的内容
$xml = records_to_xml($array,"expense");
echo $xml;

function records_to_xml($array, $xmlname){
$xml .= '<?xml version="1.0" encoding="utf-8" ?>' . "\n";
$xml .= "<$xmlname>\n";
foreach ($array as $key => $subarray){
foreach ($subarray as $k => $v){
$xml .= "<$k>$v</$k>\n";
}
}
$xml.="</$xmlname>\n";
return $xml;
}

?>
