请教大神数组转XML格式问题

本帖最后由 HUENKE 于 2013-11-04 17:51:55 编辑

我PHP存储的内容为树状递归的数组key=>value这种
转为XML为上图格式
但是
我需要如下格式的XML输出

我调试了一下午,请大神帮忙
<br />
<?xml version="1.0" encoding="utf-8"?><br />
<nodes><br />
    <node id="c5569e2c-0f4a-4ec2-86ba-736b79eca18c" name="A公司"<br />
        type="0"><br />
        <node id="4f2b55e9-e10a-496b-8bca-60e6f26daee5" name="部门1" type="1"><br />
            <node id="363" name="叶子1" type="2" playurl="http://XXXXXXX363" /><br />
        </node><br />
        <node id="0c5ce42f-ba31-4b7a-8173-79ecae4a73ca" name="部门2" type="1"><br />
            <node id="241" name="叶子1" type="2"    playurl="http://xxxxx=241" /><br />
            <node id="356" name="叶子1" type="2" playurl="xxxxxxxxx=356" /><br />

	function arrayToXml($arr, $xmlDoc = 0, $item = 0)<br />

		/*判断是否已为xml*/<br />
		if (!$xmlDoc)<br />
		{<br />
			$xmlDoc = new DOMDocument("1.0");<br />

		/*判断是否为子节点*/<br />
		if (!$item)<br />
		{<br />
			$item = $xmlDoc->createElement("nodes","UTF-8");<br />
			$xmlDoc->appendChild($item);<br />
		}<br />
		/*将数组数据按“键=>值”方式,循环取出并写入dom树*/<br />
		foreach ($arr as $key=>$val)<br />
		{<br />
			/*增加子节点名和值*/<br />
			$itemX = $xmlDoc->createElement(is_string($key) ? $key:"node");<br />
			$item->appendChild($itemX);<br />
			/*如果数组内某一元素的值也是数组,则进行递归*/<br />
			if (!is_array($val))<br />
			{<br />
				$text = $xmlDoc->createTextNode($val);<br />
				$itemX->appendChild($text);<br />
			}<br />
			else<br />
			{<br />
				$this->arrayToXml($val,$xmlDoc,$itemX); //在类中调用需加$this-><br />
			}<br />
		}<br />
		return $xmlDoc->saveXML(); //返回xml数据,可以把返回数据直接写入*.xml文件即可生成xml文件<br />
