请问一个读XML的问题.

Question

能循环出xml节点下的数据．可以节点下又有节点．不知道怎么读了．- <result>
- <item>
- <segment>
  <bookno>PBN9959</bookno> 
  <bookcode>VVN</bookcode> 
- <class>
  <c>FADYGKHTQLSNMEBURJVZIPXW</c> 
  <a>52SAQQQQQQQQQQQQASASS3AS</a> 
  </class>
  </segment>
  </item>
- <item>
- <segment>
  <bookno>PBN3151</bookno> 
  <bookcode>VVX</bookcode> 
- <class>
  <c>FAPYTKHMGSLQUEVBXNR</c> 
  <a>4Q2AQQQQQQQQAQQQQAQ</a> 
  </class>
  </segment>
  </item>
  </result>
php解析代码．部分省略了$doc->loadXML($mystrs);
$Node_Record =$doc->getElementsByTagName("item"); 
$Node_Record_Length  =$Node_Record->length;
$K=0;
for ($c=0;$c<$Node_Record_Length;$c++)
{

$K=0;
foreach ($Node_Record->item($c)->childNodes as $articles)
{ 
$Field[$K]=$articles->textContent;
$K++;
}
          }
这样读出来以后．<c>和<a>就连接到一起了．请问怎么取<c>和<a>节点的数据．.

Answer 1

php解析那里getElementsByTagName读节点误写了．应该是$Node_Record =$doc->getElementsByTagName("segment"); 

Answer 2

DOMNodeList DOMDocument::getElementsByTagName ( string $name )

Answer 3

$xml = simplexml_load_file(“xxx.xml”);XML代码：<?xml version="1.0" encoding="GBK" ?> 
- <result tag="success">
  <username>weiyg</username> 
  <uid>358066</uid> 
  <money>0</money> 
- <gameUserList gameServerID="5" count="1">
  <gameuser username="damimi123" password="123456" extend="" /> 
  </gameUserList>
  </result>  用 $xml = simplexml_load_file(“xxx.xml”);print_r($xml)是数据输出数据格式类似stdClass   SimpleXMLElement Object 
( 
    [@attributes] => Array 
        ( 
            [tag] => success 
        )     [username] => weiyg 
    [uid] => 358066 
    [money] => 0 
    [gameUserList] => SimpleXMLElement Object 
        ( 
            [@attributes] => Array 
                ( 
                    [gameServerID] => 5 
                    [count] => 1 
                )             [gameuser] => SimpleXMLElement Object 
                ( 
                    [@attributes] => Array 
                        ( 
                            [username] => damimi123 
                            [password] => 123456 
                            [extend] => 
                        )                 )         ) )
  运用$uid = $xml->uid; 
$isbind = $xml->gameUserList->attributes()->count; //是否绑定, 
$tag =  $xml->attributes(); //返回是否成功 这种方式即可取得各节点或者属性的值。参见
