PHP中使用DOM方法如何根据XML子节点值或子节点属性删除所在的父节点？

[codelifes]

如题，取得了子节点名称和值以及属性值，如何根据这些删除所在的父节点?

[程序猿之殇]

用domnode获取父节点然后再删除所在domnode
获取父节点用parentnode,删除子节点用removeChild

$strXML = <<<TEST
<?xml version="1.0"?>   
<test>   
<Transaction>   
    <Item>    
        <ItemID>280274064551</ItemID>    
    </Item>    
    <orderid>555</orderid>    
    <listid>300</listid>    
</Transaction> 
<Transaction>   
    <Item>    
        <ItemID>280274064551</ItemID>    
    </Item>    
    <orderid>555</orderid>    
    <listid>290</listid>    
</Transaction> 
</test>
TEST;

$doc = new DOMDocument;    
$doc->loadXML($strXML);    
$trans = $doc->documentElement->getElementsByTagName('Transaction');
$length = $trans->length;   

for($i=0;$i< $length; $i++)   
{
    $listid = $trans->item($i)->getElementsByTagName('listid');   
    $tmpid = $listid->item(0)->nodeValue;  
    if($tmpid == 300)
    {
    	$trans->item($i)->parentNode->removeChild($trans->item($i));
    	//$listid->parentNode->parentNode->removeChild($listid->parentNode);
    	break;
    }
}

echo $doc->saveXML();
