获取xml单层数据元素

Question

各位好，我有一个  test.xml文件，内容如下<?xml version="1.0" encoding="UTF-8"?>
<main version='2'>
<item IsFolder="1" name="folder1" addtime="2010-02-05 10:12:48">                         //目标1
<item IsFolder="0" name="e1" addtime="2010-02-05 10:11:58">content1</item>
<item IsFolder="0" name="e2" addtime="2010-08-18 08:59:41">content2</item>
<item IsFolder="0" name="e3" addtime="2010-09-27 00:24:25">content3</item>
</item>
<item IsFolder="1" name="folder2" addtime="2010-03-21 17:44:19">                        //目标2
<item IsFolder="0" name="e1" addtime="2010-03-21 17:44:19">content1</item>
<item IsFolder="0" name="e2" addtime="2010-03-21 17:44:19">content2</item>
<item IsFolder="0" name="e3" addtime="2010-03-21 17:44:19">content3</item>
<item IsFolder="0" name="e4" addtime="2010-03-21 17:44:19">content4</item>
<item IsFolder="0" name="e5" addtime="2010-03-21 17:44:19">content5</item>
<item IsFolder="0" name="e6" addtime="2010-03-21 17:44:19">content6</item>
<item IsFolder="0" name="e7" addtime="2010-03-31 08:42:57">content7</item>
</item>
<item IsFolder="0" name="f1" addtime="2010-03-21 17:44:19">contentf1</item>           //目标3
<item IsFolder="0" name="f2" addtime="2010-03-31 08:42:57">contentf2</item>           //目标4
</main>
通过以下语句可以获得相关信息： $doc->load('test.xml');
$main = $doc->getElementsByTagName("main")->item(0);
$itemiter = $main->getElementsByTagName("item");但是，$itemiter嵌套获取了所有的item元素，有没有什么方法可以至获取一层数据的，及不要嵌套。即只需要“目标1，2，3，4”这四个元素的就够了。
望赐教。谢谢。

Answer 1

这个比较麻烦，除非给你的xml节点设置ID，或者改变子节点的Tag Name和父节点区分开

Answer 2

暂时发现使用  $xml = simplexml_load_file() and  $xml->children() sounds good ,trying.

Answer 3

 $doc->load('test.xml');
$main = $doc->getElementsByTagName("main");
foreach($main as  $ma){
$test=$ma->getElementsByTagName('test')->item(0).nodeValue;
}

Answer 4

$dom = new DOMDocument();
$xml = <<<xml
<main version='2'>
    <item IsFolder="1" name="folder1" addtime="2010-02-05 10:12:48">                        
        <item IsFolder="0" name="e1" addtime="2010-02-05 10:11:58">content1</item>
        <item IsFolder="0" name="e2" addtime="2010-08-18 08:59:41">content2</item>
        <item IsFolder="0" name="e3" addtime="2010-09-27 00:24:25">content3</item>
    </item>
    <item IsFolder="1" name="folder2" addtime="2010-03-21 17:44:19">

    <item IsFolder="0" name="f2" addtime="2010-03-31 08:42:57">contentf2</item>           
</main>
xml;
$dom->loadXML($xml);$xpath = new DOMXPath($dom);$items = $xpath->query("//main/item");foreach($items as $item)
{
echo $item->getAttribute("name")."<br/>";
}
