<?xml version="1.0" encoding="utf-8"?>
<nodes>
	<node id="c5569e2c-0f4a-4ec2-86ba-736b79eca18c" name="A公司"

		<node id="4f2b55e9-e10a-496b-8bca-60e6f26daee5" name="部门1" type="1">

		</node>
		<node id="0c5ce42f-ba31-4b7a-8173-79ecae4a73ca" name="部门2" type="1">
			<node id="241" name="叶子1" type="2"	playurl="http://xxxxx=241" />
			<node id="356" name="叶子1" type="2" playurl="xxxxxxxxx=356" />
		</node>
	</node>
</nodes>

结构为 nodes下面有node下面还有node
我想做三重循环
foreach()
{
存公司名称
foreach()
{
存部门名称
foreach()
{ 存叶子名称}
}
}

请问我该怎么解析呢，

[黄袍披身]

SimpleXML 用过嘛？

[HUENKE]

SimpleXML 没解析出来 能帮简单调试一下吗

你想要怎样的数据格式？，下面自己组织一下数据结构吧

<?php
$string = <<<XML
<?xml version="1.0" encoding="utf-8"?>
<nodes>
    <node id="c5569e2c-0f4a-4ec2-86ba-736b79eca18c" name="A公司"
        type="0">
        <node id="4f2b55e9-e10a-496b-8bca-60e6f26daee5" name="部门1" type="1">
            <node id="363" name="叶子1" type="2" playurl="http://XXXXXXX363" />
        </node>
        <node id="0c5ce42f-ba31-4b7a-8173-79ecae4a73ca" name="部门2" type="1">
            <node id="241" name="叶子1" type="2"    playurl="http://xxxxx=241" />
            <node id="356" name="叶子1" type="2" playurl="xxxxxxxxx=356" />
        </node>
    </node>
</nodes>
XML;

$xml = new SimpleXMLElement($string);

$result = $xml->xpath('//node/@name');
while(list( , $node) = each($result)) {
    echo '@name: ',$node,"\n";
}
$result = $xml->xpath('//node/@id');
while(list( , $node) = each($result)) {
    echo '@id: ',$node,"\n";
}
$result = $xml->xpath('//node[@type=1]/../@id');
while(list( , $node) = each($result)) {
    echo '@部门的parent_id: ',$node,"\n";
}
$result = $xml->xpath('//node[@type=2]/../@id');
while(list( , $node) = each($result)) {
    echo '@叶子的parent_id: ',$node,"\n";
}

$s =<<< XML

XML;
$xml = simplexml_load_string($s);

foreach($xml->node as $node) {
  foreach($node->attributes() as $k=>$v) echo "$k => $v\n";
  foreach($node->node as $node) {

    foreach($node->node as $node) {

    }
  }
}

id => c5569e2c-0f4a-4ec2-86ba-736b79eca18c name => A公司 type => 0 id => 4f2b55e9-e10a-496b-8bca-60e6f26daee5 name => 部门1 type => 1 id => 363 name => 叶子1 type => 2 playurl => http://XXXXXXX363 id => 0c5ce42f-ba31-4b7a-8173-79ecae4a73ca name => 部门2 type => 1 id => 241 name => 叶子1 type => 2 playurl => http://xxxxx=241 id => 356 name => 叶子1 type => 2 playurl => xxxxxxxxx=356

[HUENKE]

就是按他原样的树状结构 如 Ａ公司 　　　　部门１ 叶子1 部门2 。。。。

[ImN1]

再给你一个吧，自己修改一下就是树状了

<?php
$string = <<<XML
<?xml version="1.0" encoding="utf-8"?>
<nodes>
    <node id="c5569e2c-0f4a-4ec2-86ba-736b79eca18c" name="A公司"
        type="0">
        <node id="4f2b55e9-e10a-496b-8bca-60e6f26daee5" name="部门1" type="1">
            <node id="363" name="叶子1" type="2" playurl="http://XXXXXXX363" />
        </node>
        <node id="0c5ce42f-ba31-4b7a-8173-79ecae4a73ca" name="部门2" type="1">
            <node id="241" name="叶子1" type="2"    playurl="http://xxxxx=241" />
            <node id="356" name="叶子1" type="2" playurl="xxxxxxxxx=356" />
        </node>
    </node>
</nodes>
XML;

$xml = new SimpleXMLElement($string);
// var_export($xml);
$xmlIterator = new RecursiveIteratorIterator(
    new SimpleXMLIterator($string),
    RecursiveIteratorIterator::SELF_FIRST
);
foreach ($xmlIterator as $nodeName => $node) {
    echo str_repeat('-', (int)$node['type']);
    echo $node['id'], ',', $node['name'], PHP_EOL;
}
?>

[ImN1]

上面#6 $xml = new SimpleXMLElement($string); 这句可以删掉，前面调试的时候留下的
