获取xml单层数据元素

Lakesy 2010-11-24 09:05:39

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。

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

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

或许用正则表达式解析试试。

 $doc->load('test.xml');

$main = $doc->getElementsByTagName("main");

foreach($main as  $ma){

$test=$ma->getElementsByTagName('test')->item(0).nodeValue;

}
