DOM读取
<?xml version="1.0" encoding="gb2312"?>
<xml>
<main>
<list>1</list>
<list>2</list>
<list>3</list>
</main>
<main>
<list>4</list>
<list>5</list>
<list>6</list>
</main>
<m>
<list>7</list>
<list>8</list>
<list>9</list>
</m>
</xml>
<?php
$xml = new DOMDocument();
$xml->load('cy.xml');
$main = $xml->getElementsByTagName('main');
foreach( $main as $main)
{
$list = $main->getElementsByTagName( "list" );
foreach ( $list as $list )
{
$value = $list->firstChild->nodeValue;
echo $value."<br />";
}
}
$m = $xml->getElementsByTagName('m');
foreach( $m as $m)
{
$list = $m->getElementsByTagName( "list" );
foreach ( $list as $list )
{
$value = $list->firstChild->nodeValue;
echo $value."<br />";
}
}
?>

<?xml version="1.0" encoding="gb2312"?>
<LevelOne>
<LevelTwo>
<LevelThree id="1">This is Text One</LevelThree>
<LevelThree id="2">This is Text Two</LevelThree>
<LevelThree id="3">This is Text Three</LevelThree>
</LevelTwo>
<LevelTwo>
<LevelThree id="4">This is Text Four</LevelThree>
<LevelThree id="5">This is Text Five</LevelThree>
<LevelThree id="6">This is Text Six</LevelThree>
</LevelTwo>
</LevelOne>
<?php
$xml = new DOMDocument(); //建立一个DOMDocument
$xml->load('cy.xml'); //Php指定需要读取xml文件的位置
$LevelOne = $xml->getElementsByTagName('LevelOne');//按照名称取得节点，返回所有节点的集合,不过这里这样读LevelOne是没有意义的....
$LevelOne = $xml->getElementsByTagName('LevelOne')->item(0);//返回第一个LevelOne节点中的内容
$LevelTwo = $LevelOne->getElementsByTagName('LevelTwo'); //按照名称取得节点,返回所有LevelTwo
foreach ( $LevelTwo as $Content )//循环读出所有LevelTwo，并在循环里，把LevelTwo用Content表示
{
$LevelThree = $Content->getElementsByTagName('LevelThree');//返回所有LevelThree
foreach ( $LevelThree as $Concert )
{
$name = $Concert->nodeName;//节点名称
$value = $Concert->nodeValue;//节点值
$id = $Concert->getAttribute('id');//"id"属性值
echo $name."<br />";
echo $value."<br />";
echo $id."<br />";
}
}
?>
$main=$doc->getElementsByTagName('main');返回的是一个集合 需要foreach遍历
$main=$doc->getElementsByTagName('main')->item(0)返回的是一个具体的节点 如果有多个<main></main>返回第一个
$name=$title->nodeName;//节点名title、list等
$value=$title->nodeValue;//节点值
